Description
SHOPPING FACILITY TRACK SYSTEM AND METHOD OF ROUTING MOTORIZED TRANSPORT UNITS
Cross-Reference To Related Application [0001] This application claims the benefit of U.S. Provisional Application No. 62/205,539, filed August 14, 2015, and which is incorporated herein by reference.
Technical Field [0002] These teachings relate generally to shopping environments and more particularly to devices, systems and methods for assisting customers and/or workers in those shopping environments.
Background [00031 In a modern retail store environment, there is a need to improve the customer experience and/or convenience for the customer. Whether shopping in a large format (big box) store or smaller format (neighborhood) store, customers often require assistance that employees of the store are not always able to provide. For example, particularly during peak hours, there may not be enough employees available to assist customers such that customer questions go unanswered. Additionally, due to high employee turnover rates, available employees may not be fully trained or have access to information to adequately support customers. Other routine tasks also are difficult to keep up with, particularly during peak hours. For example, shopping carts are left abandoned, aisles become messy, inventory is not displayed in the proper locations or is not even placed on the sales floor, shelf prices may not be properly set, and theft is hard to discourage. All of these issues can result in low customer satisfaction or reduced convenience to the customer. With increasing competition from non-traditional shopping mechanisms, such as online shopping provided by e-commerce merchants and alternative store formats, it can be important for “brick and mortar” retailers to focus on improving the overall customer experience and/or convenience.
Brief Description of the Drawings [0004] The above needs are at least partially met through provision of embodiments of systems, devices, and methods designed to provide a track system that motorized transport units can utilize in traversing parts of a shopping facility, which can in part improve customer and/or worker assistance in a shopping facility, such as described in the following detailed description, particularly when studied in conjunction with the drawings, wherein: [0005] FIG. 1 comprises a block diagram of a shopping assistance system as configured in accordance with various embodiments of these teachings; [0006] FIGS. 2 A and 2B are illustrations of a motorized transport unit of the system of FIG. 1 in a retracted orientation and an extended orientation in accordance with some embodiments; [0007] FIGS. 3A and 3B are illustrations of the motorized transport unit of FIGS. 2A and 2B detachably coupling to a movable item container, such as a shopping cart, in accordance with some embodiments; [0008] FIG. 4 comprises a block diagram of a motorized transport unit as configured in accordance with various embodiments of these teachings; [0009] FIG. 5 comprises a block diagram of a computer device as configured in accordance with various embodiments of these teachings; [0010] FIG. 6 shows a simplified overhead view of an exemplary elevated track system within a shopping facility, in accordance with some embodiments; [0011] FIG. 7 illustrates some embodiments of an exemplary elevated track of an elevated track system positioned above one or more shelving units, modulars, and other such product support units; [0012] FIG. 8 illustrates some embodiments of a portion of an exemplary elevated track of an elevated track system that include one or more staging areas; [0013] FIG. 9 illustrates a simplified flow diagram of an exemplary process of routing motorized transport units through a shopping facility, in accordance with some embodiments.

[0016] Generally speaking, pursuant to various embodiments, systems, devices and methods are provided for assistance of persons at a shopping facility. Generally, assistance may be provided to customers or shoppers at the facility and/or to workers at the facility. The facility may be any type of shopping facility at a location in which products for display and/or for sale are variously distributed throughout the shopping facility space. The shopping facility may be a retail sales facility, or any other type of facility in which products are displayed and/or sold. The shopping facility may include one or more of sales floor areas, checkout locations, parking locations, entrance and exit areas, stock room areas, stock receiving areas, hallway areas, common areas shared by merchants, and so on Generally, a shopping facility includes areas that may be dynamic in terms of the physical structures occupying the space or area and objects, items, machinery and/or persons moving in the area. For example, the shopping area may include product storage units, shelves, racks, modules, bins, etc., and other walls, dividers, partitions, etc. that may be configured in different layouts or physical arrangements. In other examples, persons or other movable objects may be freely and independently traveling through the shopping facility space. And in other examples, the persons or movable objects move according to known travel patterns and timing. The facility may be any size of format facility, and may include products from one or more merchants. For example, a facility may be a single store operated by one merchant or may be a collection of stores covering multiple merchants such as a mall. Generally, the system makes use of automated, robotic mobile devices, e.g., motorized transport units, that are capable of self-powered movement through a space of the shopping facility and providing any number of functions. Movement and operation of such devices may be controlled by a central computer system or may be autonomously controlled by the motorized transport units themselves. Various embodiments provide one or more user interfaces to allow various users to interact with the system including the automated mobile devices and/or to directly interact with the automated mobile devices. In some embodiments, the automated mobile devices and the corresponding system serve to enhance a customer shopping experience in the shopping facility, e g., by assisting shoppers and/or workers at the facility.
[0017] In some embodiments, a shopping facility personal assistance system comprises: a plurality of motorized transport units located in and configured to move through a shopping facility space; a plurality of user interface units, each corresponding to a respective motorized transport unit during use of the respective motorized transport unit; and a central computer system having a network interface such that the central computer system wirelessly communicates with one or both of the plurality of motorized transport units and the plurality of user interface units, wherein the central computer system is configured to control movement of the plurality of motorized transport units through the shopping facility space based at least on inputs from the plurality of user interface units.
[0018] SYSTEM OVERVIEW
[0019] Referring now to the drawings, FIG. 1 illustrates embodiments of a shopping facility assistance system 100 that can serve to carry out at least some of the teachings set forth herein. It will be understood that the details of this example are intended to serve in an illustrative capacity and are not necessarily intended to suggest any limitations as regards the present teachings. It is noted that generally, FIGS. 1-5 describe the general functionality of several embodiments of a system, and FIGS. 6-9 expand on some functionalities of some embodiments of the system and/or embodiments independent of such systems.
[0020] In the example of FIG. 1, a shopping assistance system 100 is implemented in whole or in part at a shopping facility 101. Generally, the system 100 includes one or more motorized transport units (MTUs) 102; one or more item containers 104; a central computer system 106 having at least one control circuit 108, at least one memory 110 and at least one network interface 112; at least one user interface unit 114; a location determination system 116; at least one video camera 118; at least one motorized transport unit (MTU) dispenser 120; at least one motorized transport unit (MTU) docking station 122; at least one wireless network 124; at least one database 126; at least one user interface computer device 128; an item display module 130; and a locker or an item storage unit 132. It is understood that more or fewer of such components may be included in different embodiments of the system 100.
[0021] These motorized transport units 102 are located in the shopping facility 101 and are configured to move throughout the shopping facility space. Further details regarding such motorized transport units 102 appear further below. Generally speaking, these motorized transport units 102 are configured to either comprise, or to selectively couple to, a corresponding movable item container 104. A simple example of an item container 104 would be a shopping cart as one typically finds at many retail facilities, or a rocket cart, a flatbed cart or any other mobile basket or platform that may be used to gather items for potential purchase.
[0022] In some embodiments, these motorized transport units 102 wirelessly communicate with, and are wholly or largely controlled by, the central computer system 106. In particular, in some embodiments, the central computer system 106 is configured to control movement of the motorized transport units 102 through the shopping facility space based on a variety of inputs. For example, the central computer system 106 communicates with each motorized transport unit 102 via the wireless network 124 which may be one or more wireless networks of one or more wireless network types (such as, a wireless local area network, a wireless personal area network, a wireless mesh network, a wireless star network, a wireless wide area network, a cellular network, and so on), capable of providing wireless coverage of the desired range of the motorized transport units 102 according to any known wireless protocols, including but not limited to a cellular, Wi-Fi, Zigbee or Bluetooth network.
[0023] By one approach the central computer system 106 is a computer based device and includes at least one control circuit 108, at least one memory 110 and at least one wired and/or wireless network interface 112. Such a control circuit 108 can comprise a fixed-purpose hard-wired platform or can comprise a partially or wholly programmable platform, such as a microcontroller, an application specification integrated circuit, a field programmable gate array, and so on. These architectural options are well known and understood in the art and require no further description here. This control circuit 108 is configured (for example, by using corresponding programming stored in the memory 110 as will be well understood by those skilled in the art) to carry out one or more of the steps, actions, and/or functions described herein.
[0024] In this illustrative example the control circuit 108 operably couples to one or more memories 110. The memory 110 may be integral to the control circuit 108 or can be physically discrete (in whole or in part) from the control circuit 108 as desired. This memory 110 can also be local with respect to the control circuit 108 (where, for example, both share a common circuit board, chassis, power supply, and/or housing) or can be partially or wholly remote with respect to the control circuit 108 (where, for example, the memory 110 is physically located in another facility, metropolitan area, or even country as compared to the control circuit 108).
[0025] This memory 110 can serve, for example, to non-transitorily store the computer instructions that, when executed by the control circuit 108, cause the control circuit 108 to behave as described herein. (As used herein, this reference to “non-transitorily” will be understood to refer to a non-ephemeral state for the stored contents (and hence excludes when the stored contents merely constitute signals or waves) rather than volatility of the storage media itself and hence includes both non-volatile memory (such as read-only memory (ROM) as well as volatile memory (such as an erasable programmable read-only memory (EPROM).) [0026] Additionally, at least one database 126 may be accessible by the central computer system 106. Such databases may be integrated into the central computer system 106 or separate from it. Such databases may be at the location of the shopping facility 101 or remote from the shopping facility 101. Regardless of location, the databases comprise memory to store and organize certain data for use by the central control system 106. In some embodiments, the at least one database 126 may store data pertaining to one or more of: shopping facility mapping data, customer data, customer shopping data and patterns, inventory data, product pricing data, and so on.
[0027] In this illustrative example, the central computer system 106 also wirelessly communicates with a plurality of user interface units 114. These teachings will accommodate a variety of user interface units including, but not limited to, mobile and/or handheld electronic devices such as so-called smart phones and portable computers such as tablet/pad-styled computers. Generally speaking, these user interface units 114 should be able to wirelessly communicate with the central computer system 106 via a wireless network, such as the wireless network 124 of the shopping facility 101 (such as a Wi-Fi wireless network). These user interface units 114 generally provide a user interface for interaction with the system. In some embodiments, a given motorized transport unit 102 is paired with, associated with, assigned to or otherwise made to correspond with a given user interface unit 114. In some embodiments, these user interface units 114 should also be able to receive verbally-expressed input from a user and forward that content to the central computer system 106 or a motorized transport unit 102 and/or convert that verbally-expressed input into a form useful to the central computer system 106 or a motorized transport unit 102.
[0028] By one approach at least some of the user interface units 114 belong to corresponding customers who have come to the shopping facility 101 to shop. By another approach, in lieu of the foregoing or in combination therewith, at least some of the user interface units 114 belong to the shopping facility 101 and are loaned to individual customers to employ as described herein. In some embodiments, one or more user interface units 114 are attachable to a given movable item container 104 or are integrated with the movable item container 104. Similarly, in some embodiments, one or more user interface units 114 may be those of shopping facility workers, belong to the shopping facility 101 and are loaned to the workers, or a combination thereof.
[0029] In some embodiments, the user interface units 114 may be general purpose computer devices that include computer programming code to allow it to interact with the system 106. For example, such programming may be in the form of an application installed on the user interface unit 114 or in the form of a browser that displays a user interface provided by the central computer system 106 or other remote computer or server (such as a web server). In some embodiments, one or more user interface units 114 may be special purpose devices that are programmed to primarily function as a user interface for the system 100. Depending on the functionality and use case, user interface units 114 may be operated by customers of the shopping facility or may be operated by workers at the shopping facility, such as facility employees (associates or colleagues), vendors, suppliers, contractors, etc.
[0030] By one approach, the system 100 optionally includes one or more video cameras 118. Captured video imagery from such a video camera 118 can be provided to the central computer system 106. That information can then serve, for example, to help the central computer system 106 determine a present location of one or more of the motorized transport units 102 and/or determine issues or concerns regarding automated movement of those motorized transport units 102 in the shopping facility space. As one simple example in these regards, such video information can permit the central computer system 106, at least in part, to detect an object in a path of movement of a particular one of the motorized transport units 102.
[0031] By one approach these video cameras 118 comprise existing surveillance equipment employed at the shopping facility 101 to serve, for example, various security purposes. By another approach these video cameras 118 are dedicated to providing video content to the central computer system 106 to facilitate the latter’s control of the motorized transport units 102. If desired, the video cameras 118 can have a selectively movable field of view and/or zoom capability that the central computer system 106 controls as appropriate to help ensure receipt of useful information at any given moment.
[0032] In some embodiments, a location detection system 116 is provided at the shopping facility 101. The location detection system 116 provides input to the central computer system 106 useful to help determine the location of one or more of the motorized transport units 102. In some embodiments, the location detection system 116 includes a series of light sources (e.g., LEDs (light-emitting diodes)) that are mounted in the ceiling at known positions throughout the space and that each encode data in the emitted light that identifies the source of the light (and thus, the location of the light). As a given motorized transport unit 102 moves through the space, light sensors (or light receivers) at the motorized transport unit 102, on the movable item container 104 and/or at the user interface unit 114 receive the light and can decode the data. This data is sent back to the central computer system 106 which can determine the position of the motorized transport unit 102 by the data of the light it receives, since it can relate the light data to a mapping of the light sources to locations at the facility 101. Generally, such lighting systems are known and commercially available, e g., the ByteLight system from ByteLight of Boston, Massachusetts. In embodiments using a ByteLight system, a typical display screen of the typical smart phone device can be used as a light sensor or light receiver to receive and process data encoded into the light from the ByteLight light sources.
[0033] In other embodiments, the location detection system 116 includes a series of low energy radio beacons (e g., Bluetooth low energy beacons) at known positions throughout the space and that each encode data in the emitted radio signal that identifies the beacon (and thus, the location of the beacon). As a given motorized transport unit 102 moves through the space, low energy receivers at the motorized transport unit 102, on the movable item container 104 and/or at the user interface unit 114 receive the radio signal and can decode the data. This data is sent back to the central computer system 106 which can determine the position of the motorized transport unit 102 by the location encoded in the radio signal it receives, since it can relate the location data to a mapping of the low energy radio beacons to locations at the facility 101. Generally, such low energy radio systems are known and commercially available. In embodiments using a Bluetooth low energy radio system, a typical Bluetooth radio of a typical smart phone device can be used as a receiver to receive and process data encoded into the Bluetooth low energy radio signals from the Bluetooth low energy beacons.
[0034] In still other embodiments, the location detection system 116 includes a series of audio beacons at known positions throughout the space and that each encode data in the emitted audio signal that identifies the beacon (and thus, the location of the beacon). As a given motorized transport unit 102 moves through the space, microphones at the motorized transport unit 102, on the movable item container 104 and/or at the user interface unit 114 receive the audio signal and can decode the data. This data is sent back to the central computer system 106 which can determine the position of the motorized transport unit 102 by the location encoded in the audio signal it receives, since it can relate the location data to a mapping of the audio beacons to locations at the facility 101. Generally, such audio beacon systems are known and commercially available. In embodiments using an audio beacon system, a typical microphone of a typical smart phone device can be used as a receiver to receive and process data encoded into the audio signals from the audio beacon.
[0035] Also optionally, the central computer system 106 can operably couple to one or more user interface computers 128 (comprising, for example, a display and a user input interface such as a keyboard, touch screen, and/or cursor-movement device). Such a user interface computer 128 can permit, for example, a worker (e.g., an associate, analyst, etc.) at the retail or shopping facility 101 to monitor the operations of the central computer system 106 and/or to attend to any of a variety of administrative, configuration or evaluation tasks as may correspond to the programming and operation of the central computer system 106. Such user interface computers 128 may be at or remote from the location of the facility 101 and may access one or more the databases 126.
[0036] In some embodiments, the system 100 includes at least one motorized transport unit (MTU) storage unit or dispenser 120 at various locations in the shopping facility 101. The dispenser 120 provides for storage of motorized transport units 102 that are ready to be assigned to customers and/or workers. In some embodiments, the dispenser 120 takes the form of a cylinder within which motorized transports units 102 are stacked and released through the bottom of the dispenser 120. Further details of such embodiments are provided further below. In some embodiments, the dispenser 120 may be fixed in location or may be mobile and capable of transporting itself to a given location or utilizing a motorized transport unit 102 to transport the dispenser 120, then dispense one or more motorized transport units 102.
[0037] In some embodiments, the system 100 includes at least one motorized transport unit (MTU) docking station 122. These docking stations 122 provide locations where motorized transport units 102 can travel and connect to. For example, the motorized transport units 102 may be stored and charged at the docking station 122 for later use, and/or may be serviced at the docking station 122.
[0038] In accordance with some embodiments, a given motorized transport unit 102 detachably connects to a movable item container 104 and is configured to move the movable item container 104 through the shopping facility space under control of the central computer system 106 and/or the user interface unit 114. For example, a motorized transport unit 102 can move to a position underneath a movable item container 104 (such as a shopping cart, a rocket cart, a flatbed cart, or any other mobile basket or platform), align itself with the movable item container 104 (e.g., using sensors) and then raise itself to engage an undersurface of the movable item container 104 and lift a portion of the movable item container 104. Once the motorized transport unit is cooperating with the movable item container 104 (e.g., lifting a portion of the movable item container), the motorized transport unit 102 can continue to move throughout the facility space 101 taking the movable item container 104 with it. In some examples, the motorized transport unit 102 takes the form of the motorized transport unit 202 of FIGS. 2A-3B as it engages and detachably connects to a given movable item container 104. It is understood that in other embodiments, the motorized transport unit 102 may not lift a portion of the movable item container 104, but that it removably latches to, connects to or otherwise attaches to a portion of the movable item container 104 such that the movable item container 104 can be moved by the motorized transport unit 102. For example, the motorized transport unit 102 can connect to a given movable item container using a hook, a mating connector, a magnet, and so on.
[0039] In addition to detachably coupling to movable item containers 104 (such as shopping carts), in some embodiments, motorized transport units 102 can move to and engage or connect to an item display module 130 and/or an item storage unit or locker 132. For example, an item display module 130 may take the form of a mobile display rack or shelving unit configured to house and display certain items for sale. It may be desired to position the display module 130 at various locations within the shopping facility 101 at various times. Thus, one or more motorized transport units 102 may move (as controlled by the central computer system 106) underneath the item display module 130, extend upward to lift the module 130 and then move it to the desired location. A storage locker 132 may be a storage device where items for purchase are collected and placed therein for a customer and/or worker to later retrieve. In some embodiments, one or more motorized transport units 102 may be used to move the storage locker to a desired location in the shopping facility 101. Similar to how a motorized transport unit engages a movable item container 104 or item display module 130, one or more motorized transport units 102 may move (as controlled by the central computer system 106) underneath the storage locker 132, extend upward to lift the locker 132 and then move it to the desired location.
[0040] FIGS. 2A and 2B illustrate some embodiments of a motorized transport unit 202, similar to the motorized transport unit 102 shown in the system of FIG. 1. In this embodiment, the motorized transport unit 202 takes the form of a disc-shaped robotic device having motorized wheels (not shown), a lower body portion 204 and an upper body portion 206 that fits over at least part of the lower body portion 204. It is noted that in other embodiments, the motorized transport unit may have other shapes and/or configurations, and is not limited to disc-shaped. For example, the motorized transport unit may be cubic, octagonal, triangular, or other shapes, and may be dependent on a movable item container with which the motorized transport unit is intended to cooperate. Also included are guide members 208. In FIG. 2A, the motorized transport unit 202 is shown in a retracted position in which the upper body portion 206 fits over the lower body portion 204 such that the motorized transport unit 202 is in its lowest profile orientation which is generally the preferred orientation for movement when it is unattached to a movable item container 104 for example. In FIG. 2B, the motorized transport unit 202 is shown in an extended position in which the upper body portion 206 is moved upward relative to the lower body portion 204 such that the motorized transport unit 202 is in its highest profile orientation for movement when it is lifting and attaching to a movable item container 104 for example. The mechanism within the motorized transport unit 202 is designed to provide sufficient lifting force to lift the weight of the upper body portion 206 and other objects to be lifted by the motorized transport unit 202, such as movable item containers 104 and items placed within the movable item container, item display modules 130 and items supported by the item display module, and storage lockers 132 and items placed within the storage locker. The guide members 208 are embodied as pegs or shafts that extend horizontally from the both the upper body portion 206 and the lower body portion 204. In some embodiments, these guide members 208 assist docking the motorized transport unit 202 to a docking station 122 or a dispenser 120. In some embodiments, the lower body portion 204 and the upper body portion are capable to moving independently of each other. For example, the upper body portion 206 may be raised and/or rotated relative to the lower body portion 204. That is, one or both of the upper body portion 206 and the lower body portion 204 may move toward/away from the other or rotated relative to the other. In some embodiments, in order to raise the upper body portion 206 relative to the lower body portion 204, the motorized transport unit 202 includes an internal lifting system (e g., including one or more electric actuators or rotary drives or motors). Numerous examples of such motorized lifting and rotating systems are known in the art. Accordingly, further elaboration in these regards is not provided here for the sake of brevity.
[0041] FIGS. 3 A and 3B illustrate some embodiments of the motorized transport unit 202 detachably engaging a movable item container embodied as a shopping cart 302. In FIG 3 A, the motorized transport unit 202 is in the orientation of FIG. 2A such that it is retracted and able to move in position underneath a portion of the shopping cart 302. Once the motorized transport unit 202 is in position (e.g., using sensors), as illustrated in FIG. 3B, the motorized transport unit 202 is moved to the extended position of FIG. 2B such that the front portion 304 of the shopping cart is lifted off of the ground by the motorized transport unit 202, with the wheels 306 at the rear of the shopping cart 302 remaining on the ground. In this orientation, the motorized transport unit 202 is able to move the shopping cart 302 throughout the shopping facility. It is noted that in these embodiments, the motorized transport unit 202 does not bear the weight of the entire cart 302 since the rear wheels 306 rest on the floor. It is understood that in some embodiments, the motorized transport unit 202 may be configured to detachably engage other types of movable item containers, such as rocket carts, flatbed carts or other mobile baskets or platforms.
[0042] FIG. 4 presents a more detailed example of some embodiments of the motorized transport unit 102 of FIG. 1. In this example, the motorized transport unit 102 has a housing 402 that contains (partially or fully) or at least supports and carries a number of components. These components include a control unit 404 comprising a control circuit 406 that, like the control circuit 108 of the central computer system 106, controls the general operations of the motorized transport unit 102. Accordingly, the control unit 404 also includes a memory 408 coupled to the control circuit 406 and that stores, for example, operating instructions and/or useful data.
[0043] The control circuit 406 operably couples to a motorized wheel system 410. This motorized wheel system 410 functions as a locomotion system to permit the motorized transport unit 102 to move within the aforementioned retail or shopping facility 101 (thus, the motorized wheel system 410 may more generically be referred to as a locomotion system). Generally speaking, this motorized wheel system 410 will include at least one drive wheel (i.e., a wheel that rotates (around a horizontal axis) under power to thereby cause the motorized transport unit 102 to move through interaction with, for example, the floor of the shopping facility 101). The motorized wheel system 410 can include any number of rotating wheels and/or other floor-contacting mechanisms as may be desired and/or appropriate to the application setting.
[0044] The motorized wheel system 410 also includes a steering mechanism of choice. One simple example in these regards comprises one or more of the aforementioned wheels that can swivel about a vertical axis to thereby cause the moving motorized transport unit 102 to turn as well.
[0045] Numerous examples of motorized wheel systems are known in the art. Accordingly, further elaboration in these regards is not provided here for the sake of brevity save to note that the aforementioned control circuit 406 is configured to control the various operating states of the motorized wheel system 410 to thereby control when and how the motorized wheel system 410 operates.
[0046] In this illustrative example, the control circuit 406 also operably couples to at least one wireless transceiver 412 that operates according to any known wireless protocol. This wireless transceiver 412 can comprise, for example, a Wi-Fi-compatible and/or Bluetooth-compatible transceiver that can communicate with the aforementioned central computer system 106 via the aforementioned wireless network 124 of the shopping facility 101. So configured the control circuit 406 of the motorized transport unit 102 can provide information to the central computer system 106 and can receive information and/or instructions from the central computer system 106. As one simple example in these regards, the control circuit 406 can receive instructions from the central computer system 106 regarding movement of the motorized transport unit 102.
[0047] These teachings will accommodate using any of a wide variety of wireless technologies as desired and/or as may be appropriate in a given application setting. These teachings will also accommodate employing two or more different wireless transceivers 412 if desired.
[0048] The control circuit 406 also couples to one or more on-board sensors 414. These teachings will accommodate a wide variety of sensor technologies and form factors.
By one approach at least one such sensor 414 can comprise a light sensor or light receiver. When the aforementioned location detection system 116 comprises a plurality of light emitters disposed at particular locations within the shopping facility 101, such a light sensor can provide information that the control circuit 406 and/or the central computer system 106 employs to determine a present location and/or orientation of the motorized transport unit 102.
[0049] As another example, such a sensor 414 can comprise a distance measurement unit configured to detect a distance between the motorized transport unit 102 and one or more objects or surfaces around the motorized transport unit 102 (such as an object that lies in a projected path of movement for the motorized transport unit 102 through the shopping facility 101). These teachings will accommodate any of a variety of distance measurement units including optical units and sound/ultrasound units. In one example, a sensor 414 comprises a laser distance sensor device capable of determining a distance to objects in proximity to the sensor. In some embodiments, a sensor 414 comprises an optical based scanning device to sense and read optical patterns in proximity to the sensor, such as bar codes variously located on structures in the shopping facility 101. In some embodiments, a sensor 414 comprises a radio frequency identification (RFID) tag reader capable of reading RFID tags in proximity to the sensor. Such sensors may be useful to determine proximity to nearby objects, avoid collisions, orient the motorized transport unit at a proper alignment orientation to engage a movable item container, and so on.
[0050] The foregoing examples are intended to be illustrative and are not intended to convey an exhaustive listing of all possible sensors. Instead, it will be understood that these teachings will accommodate sensing any of a wide variety of circumstances or phenomena to support the operating functionality of the motorized transport unit 102 in a given application setting.
[0051] By one optional approach an audio input 416 (such as a microphone) and/or an audio output 418 (such as a speaker) can also operably couple to the control circuit 406. So configured the control circuit 406 can provide a variety of audible sounds to thereby communicate with a user of the motorized transport unit 102, other persons in the vicinity of the motorized transport unit 102, or even other motorized transport units 102 in the area. These audible sounds can include any of a variety of tones and other non-verbal sounds.
These audible sounds can also include, in lieu of the foregoing or in combination therewith, pre-recorded or synthesized speech.
[0052] The audio input 416, in turn, provides a mechanism whereby, for example, a user provides verbal input to the control circuit 406. That verbal input can comprise, for example, instructions, inquiries, or information. So configured, a user can provide, for example, a question to the motorized transport unit 102 (such as, “Where are the towels?”). The control circuit 406 can cause that verbalized question to be transmitted to the central computer system 106 via the motorized transport unit’s wireless transceiver 412. The central computer system 106 can process that verbal input to recognize the speech content and to then determine an appropriate response. That response might comprise, for example, transmitting back to the motorized transport unit 102 specific instructions regarding how to move the motorized transport unit 102 (via the aforementioned motorized wheel system 410) to the location in the shopping facility 101 where the towels are displayed.
[0053] In this example the motorized transport unit 102 includes a rechargeable power source 420 such as one or more batteries. The power provided by the rechargeable power source 420 can be made available to whichever components of the motorized transport unit 102 require electrical energy. By one approach the motorized transport unit 102 includes a plug or other electrically conductive interface that the control circuit 406 can utilize to automatically connect to an external source of electrical energy to thereby recharge the rechargeable power source 420.
[0054] By one approach the motorized transport unit 102 comprises an integral part of a movable item container 104 such as a grocery cart. As used herein, this reference to “integral” will be understood to refer to a non-temporary combination and joinder that is sufficiently complete so as to consider the combined elements to be as one. Such a joinder can be facilitated in a number of ways including by securing the motorized transport unit housing 402 to the item container using bolts or other threaded fasteners as versus, for example, a clip.
[0055] These teachings will also accommodate selectively and temporarily attaching the motorized transport unit 102 to an item container 104. In such a case the motorized transport unit 102 can include a movable item container coupling structure 422. By one approach this movable item container coupling structure 422 operably couples to a control circuit 202 to thereby permit the latter to control, for example, the latched and unlatched states of the movable item container coupling structure 422. So configured, by one approach the control circuit 406 can automatically and selectively move the motorized transport unit 102 (via the motorized wheel system 410) towards a particular item container until the movable item container coupling structure 422 can engage the item container to thereby temporarily physically couple the motorized transport unit 102 to the item container. So latched, the motorized transport unit 102 can then cause the item container to move with the motorized transport unit 102. In embodiments such as illustrated in FIGS. 2A-3B, the movable item container coupling structure 422 includes a lifting system (e.g., including an electric drive or motor) to cause a portion of the body or housing 402 to engage and lift a portion of the item container off of the ground such that the motorized transport unit 102 can carry a portion of the item container. In other embodiments, the movable transport unit latches to a portion of the movable item container without lifting a portion thereof off of the ground.
[0056] In either case, by combining the motorized transport unit 102 with an item container, and by controlling movement of the motorized transport unit 102 via the aforementioned central computer system 106, these teachings will facilitate a wide variety of useful ways to assist both customers and associates in a shopping facility setting. For example, the motorized transport unit 102 can be configured to follow a particular customer as they shop within the shopping facility 101. The customer can then place items they intend to purchase into the item container that is associated with the motorized transport unit 102.
[0057] In some embodiments, the motorized transport unit 102 includes an input/output (I/O) device 424 that is coupled to the control circuit 406. The I/O device 424 allows an external device to couple to the control unit 404. The function and purpose of connecting devices will depend on the application. In some examples, devices connecting to the I/O device 424 may add functionality to the control unit 404, allow the exporting of data from the control unit 404, allow the diagnosing of the motorized transport unit 102, and so on.
[0058] In some embodiments, the motorized transport unit 102 includes a user interface 426 including for example, user inputs and/or user outputs or displays depending on the intended interaction with the user. For example, user inputs could include any input device such as buttons, knobs, switches, touch sensitive surfaces or display screens, and so on. Example user outputs include lights, display screens, and so on. The user interface 426 may work together with or separate from any user interface implemented at a user interface unit 114 (such as a smart phone or tablet device).
[0059] The control unit 404 includes a memory 408 coupled to the control circuit 406 and that stores, for example, operating instructions and/or useful data. The control circuit 406 can comprise a fixed-purpose hard-wired platform or can comprise a partially or wholly programmable platform. These architectural options are well known and understood in the art and require no further description here. This control circuit 406 is configured (for example, by using corresponding programming stored in the memory 408 as will be well understood by those skilled in the art) to carry out one or more of the steps, actions, and/or functions described herein. The memory 408 may be integral to the control circuit 406 or can be physically discrete (in whole or in part) from the control circuit 406 as desired. This memory 408 can also be local with respect to the control circuit 406 (where, for example, both share a common circuit board, chassis, power supply, and/or housing) or can be partially or wholly remote with respect to the control circuit 406. This memory 408 can serve, for example, to non-transitorily store the computer instructions that, when executed by the control circuit 406, cause the control circuit 406 to behave as described herein. (As used herein, this reference to “non-transitorily” will be understood to refer to a non-ephemeral state for the stored contents (and hence excludes when the stored contents merely constitute signals or waves) rather than volatility of the storage media itself and hence includes both non-volatile memory (such as read-only memory (ROM) as well as volatile memory (such as an erasable programmable read-only memory (EPROM).) [0060] It is noted that not all components illustrated in FIG. 4 are included in all embodiments of the motorized transport unit 102. That is, some components may be optional depending on the implementation.
[0061] FIG. 5 illustrates a functional block diagram that may generally represent any number of various electronic components of the system 100 that are computer type devices. The computer device 500 includes a control circuit 502, a memory 504, a user interface 506 and an input/output (I/O) interface 508 providing any type of wired and/or wireless connectivity to the computer device 500, all coupled to a communication bus 510 to allow data and signaling to pass therebetween. Generally, the control circuit 502 and the memory 504 may be referred to as a control unit. The control circuit 502, the memory 504, the user interface 506 and the I/O interface 508 may be any of the devices described herein or as understood in the art. The functionality of the computer device 500 will depend on the programming stored in the memory 504. The computer device 500 may represent a high level diagram for one or more of the central computer system 106, the motorized transport unit 102, the user interface unit 114, the location detection system 116, the user interface computer 128, the MTU docking station 122 and the MTU dispenser 120, or any other device or component in the system that is implemented as a computer device.
[0062] ADDITIONAL FEATURES OVERVIEW
[0063] Referring generally to FIGS. 1-5, the shopping assistance system 100 may implement one or more of several different features depending on the configuration of the system and its components. The following provides a brief description of several additional features that could be implemented by the system. One or more of these features could also be implemented in other systems separate from embodiments of the system. This is not meant to be an exhaustive description of all features and not meant to be an exhaustive description of the details any one of the features. Further details with regards to one or more features beyond this overview may be provided herein.
[0064] Tagalong Steering: This feature allows a given motorized transport unit 102 to lead or follow a user (e g., a customer and/or a worker) throughout the shopping facility 101. For example, the central computer system 106 uses the location detection system 116 to determine the location of the motorized transport unit 102. For example, LED smart lights (eg., the ByteLight system) of the location detection system 116 transmit a location number to smart devices which are with the customer (e g., user interface units 114), and/or on the item container 104/motorized transport unit 102. The central computer system 106 receives the LED location numbers received by the smart devices through the wireless network 124. Using this information, in some embodiments, the central computer system 106 uses a grid placed upon a 2D CAD map and 3D point cloud model (e g., from the databases 126) to direct, track, and plot paths for the other devices. Using the grid, the motorized transport unit 102 can drive a movable item container 104 in a straight path rather than zigzagging around the facility. As the user moves from one grid to another, the motorized transport unit 102 drives the container 104 from one grid to the other. In some embodiments, as the user moves towards the motorized transport unit, it stays still until the customer moves beyond an adjoining grid.
[0065] Detecting Objects: In some embodiments, motorized transport units 102 detect objects through several sensors mounted on motorized transport unit 102, through independent cameras (e.g., video cameras 118), through sensors of a corresponding movable item container 104, and through communications with the central computer system 106. In some embodiments, with semi-autonomous capabilities, the motorized transport unit 102 will attempt to avoid obstacles, and if unable to avoid, it will notify the central computer system 106 of an exception condition. In some embodiments, using sensors 414 (such as distance measurement units, e.g., laser or other optical-based distance measurement sensors), the motorized transport unit 102 detects obstacles in its path, and will move to avoid, or stop until the obstacle is clear.
[0066] Visual Remote Steering: This feature enables movement and/or operation of a motorized transport unit 102 to be controlled by a user on-site, off-site, or anywhere in the world. This is due to the architecture of some embodiments where the central computer system 106 outputs the control signals to the motorized transport unit 102. These controls signals could have originated at any device in communication with the central computer system 106. For example, the movement signals sent to the motorized transport unit 102 may be movement instructions determined by the central computer system 106; commands received at a user interface unit 114 from a user; and commands received at the central computer system 106 from a remote user not located at the shopping facility space.
[0067] Determining Location: Similar to that described above, this feature enables the central computer system 106 to determine the location of devices in the shopping facility 101. For example, the central computer system 106 maps received LED light transmissions, Bluetooth low energy radio signals or audio signals (or other received signals encoded with location data) to a 2D map of the shopping facility. Objects within the area of the shopping facility are also mapped and associated with those transmissions. Using this information, the central computer system 106 can determine the location of devices such as motorized transport units.
[0068] Digital Physical Map Integration: In some embodiments, the system 100 is capable of integrating 2D and 3D maps of the shopping facility with physical locations of objects and workers. Once the central computer system 106 maps all objects to specific locations using algorithms, measurements and LED geo-location, for example, grids are applied which sections off the maps into access ways and blocked sections. Motorized transport units 102 use these grids for navigation and recognition. In some cases, grids are applied to 2D horizontal maps along with 3D models. In some cases, grids start at a higher unit level and then can be broken down into smaller units of measure by the central computer system 106 when needed to provide more accuracy.
[0069] Calling a Motorized Transport Unit: This feature provides multiple methods to request and schedule a motorized transport unit 102 for assistance in the shopping facility. In some embodiments, users can request use of a motorized transport unit 102 through the user interface unit 114. The central computer system 106 can check to see if there is an available motorized transport unit. Once assigned to a given user, other users will not be able to control the already assigned transport unit. Workers, such as store associates, may also reserve multiple motorized transport units in order to accomplish a coordinated large job.
[0070] Locker Delivery: In some embodiments, one or more motorized transport units 102 may be used to pick, pack, and deliver items to a particular storage locker 132. The motorized transport units 102 can couple to and move the storage locker to a desired location. In some embodiments, once delivered, the requestor will be notified that the items are ready to be picked up, and will be provided the locker location and locker security code key.
[0071] Route Optimization: In some embodiments, the central computer system automatically generates a travel route for one or more motorized transport units through the shopping facility space. In some embodiments, this route is based on one or more of a user provided list of items entered by the user via a user interface unit 114; user selected route preferences entered by the user via the user interface unit 114; user profile data received from a user information database (e.g., from one of databases 126); and product availability information from a retail inventory database (e g., from one of databases 126). In some cases, the route intends to minimize the time it takes to get through the facility, and in some cases, may route the shopper to the least busy checkout area. Frequently, there will be multiple possible optimum routes. The route chosen may take the user by things the user is more likely to purchase (in case they forgot something), and away from things they are not likely to buy (to avoid embarrassment). That is, routing a customer through sporting goods, women’s lingerie, baby food, or feminine products, who has never purchased such products based on past customer behavior would be non-productive, and potentially embarrassing to the customer. In some cases, a route may be determined from multiple possible routes based on past shopping behavior, e g., if the customer typically buys a cold Diet Coke product, children’s shoes or power tools, this information would be used to add weight to the best alternative routes, and determine the route accordingly.
[0072] Store Facing Features: In some embodiments, these features enable functions to support workers in performing store functions. For example, the system can assist workers to know what products and items are on the shelves and which ones need attention. For example, using 3D scanning and point cloud measurements, the central computer system can determine where products are supposed to be, enabling workers to be alerted to facing or zoning of issues along with potential inventory issues.
[0073] Phone Home: This feature allows users in a shopping facility 101 to be able to contact remote users who are not at the shopping facility 101 and include them in the shopping experience. For example, the user interface unit 114 may allow the user to place a voice call, a video call, or send a text message. With video call capabilities, a remote person can virtually accompany an in-store shopper, visually sharing the shopping experience while seeing and talking with the shopper. One or more remote shoppers may join the experience.
[0074] Returns: In some embodiments, the central computer system 106 can task a motorized transport unit 102 to keep the returns area clear of returned merchandise. For example, the transport unit may be instructed to move a cart from the returns area to a different department or area. Such commands may be initiated from video analytics (the central computer system analyzing camera footage showing a cart full), from an associate command (digital or verbal), or on a schedule, as other priority tasks allow. The motorized transport unit 102 can first bring an empty cart to the returns area, prior to removing a full one.
[0075] Bring a Container: One or more motorized transport units can retrieve a movable item container 104 (such as a shopping cart) to use. For example, upon a customer or worker request, the motorized transport unit 102 can re-position one or more item containers 104 from one location to another. In some cases, the system instructs the motorized transport unit where to obtain an empty item container for use. For example, the system can recognize an empty and idle item container that has been abandoned or instruct that one be retrieved from a cart storage area. In some cases, the call to retrieve an item container may be initiated through a call button placed throughout the facility, or through the interface of a user interface unit 114.
[0076] Respond to Voice Commands: In some cases, control of a given motorized transport unit is implemented through the acceptance of voice commands. For example, the user may speak voice commands to the motorized transport unit 102 itself and/or to the user interface unit 114. In some embodiments, a voice print is used to authorize to use of a motorized transport unit 102 to allow voice commands from single user at a time.
[0077] Retrieve Abandoned Item Containers: This feature allows the central computer system to track movement of movable item containers in and around the area of the shopping facility 101, including both the sale floor areas and the back-room areas. For example, using visual recognition through store cameras 118 or through user interface units 114, the central computer system 106 can identify abandoned and out-of-place movable item containers. In some cases, each movable item container has a transmitter or smart device which will send a unique identifier to facilitate tracking or other tasks and its position using LED geo-location identification. Using LED geo-location identification with the Determining Location feature through smart devices on each cart, the central computer system 106 can determine the length of time a movable item container 104 is stationary.
[0078] Stocker Assistance: This feature allows the central computer system to track movement of merchandise flow into and around the back-room areas. For example, using visual recognition and captured images, the central computer system 106 can determine if carts are loaded or not for moving merchandise between the back room areas and the sale floor areas. Tasks or alerts may be sent to workers to assign tasks.
[0079] Self-Docking: Motorized transport units 102 will run low or out of power when used. Before this happens, the motorized transport units 102 need to recharge to stay in service. According to this feature, motorized transport units 102 will self-dock and recharge (e.g., at a MTU docking station 122) to stay at maximum efficiency, when not in use. When use is completed, the motorized transport unit 102 will return to a docking station 122. In some cases, if the power is running low during use, a replacement motorized transport unit can be assigned to move into position and replace the motorized transport unit with low power. The transition from one unit to the next can be seamless to the user.
[0080] Item Container Retrieval: With this feature, the central computer system 106 can cause multiple motorized transport units 102 to retrieve abandoned item containers from exterior areas such as parking lots. For example, multiple motorized transport units are loaded into a movable dispenser, e.g., the motorized transport units are vertically stacked in the dispenser. The dispenser is moved to the exterior area and the transport units are dispensed. Based on video analytics, it is determined which item containers 104 are abandoned and for how long. A transport unit will attach to an abandoned cart and return it to a storage bay.
[0081] Motorized Transport Unit Dispenser: This feature provides the movable dispenser that contains and moves a group of motorized transport units to a given area (e.g., an exterior area such as a parking lot) to be dispensed for use. For example, motorized transport units can be moved to the parking lot to retrieve abandoned item containers 104. In some cases, the interior of the dispenser includes helically wound guide rails that mate with the guide member 208 to allow the motorized transport units to be guided to a position to be dispensed.
[0082] Specialized Module Retrieval: This feature allows the system 100 to track movement of merchandise flow into and around the sales floor areas and the back-room areas including special modules that may be needed to move to the sales floor. For example, using video analytics, the system can determine if a modular unit it loaded or empty. Such modular units may house items that are of seasonal or temporary use on the sales floor. For example, when it is raining, it is useful to move a module unit displaying umbrellas from a back room area (or a lesser accessed area of the sales floor) to a desired area of the sales floor area.
[0083] Authentication: This feature uses a voice imprint with an attention code/word to authenticate a user to a given motorized transport unit. One motorized transport unit can be swapped for another using this authentication. For example, a token is used during the session with the user. The token is a unique identifier for the session which is dropped once the session is ended. A logical token may be a session id used by the application of the user interface unit 114 to establish the session id when user logs on and when deciding to do use the system 100. In some embodiments, communications throughout the session are encrypted using SSL or other methods at transport level.
[0084] FURTHER DETAILS OF SOME EMBODIMENTS
[0085] In accordance with some embodiments, further details are now provided for one or more of these and other features. For example, generally speaking, pursuant to various embodiments, systems, apparatuses, processes and methods are provided herein that allow the motorized transport units to travel through the shopping facility while limiting congestion, in reduced time, while limiting potential conflicts and/or contact with customer, and other such advantage by providing alternate travel routes that are typically not available to at least customers. Some embodiments provide an elevated track system that provides alternate tracks on and/or through which the motorized transport units can travel. The elevated track system can include tracks that are positioned such that the tracks do not interfere with movement of customers through the sales floor. In some implementations, some or all of the tracks of the track system can include tracks that are positioned elevated above a sales floor, and typically above shelves, modulars, racks and products distributed over at least a portion of the sales floor of a shopping facility. Additionally or alternatively, the track system may include one or more tracks that are below typical flooring (such as the sales floor), routed through sub-levels below a sales floor (e.g., basements, parking structures, etc ), inside structures (e g., walls, shelving, between shelves, and the like), and/or other areas or space of the shopping facility, such as space that is typically not used or underutilized.
[0086] FIG. 6 shows a simplified overhead view of an exemplary elevated track system 600 within a shopping facility 601, in accordance with some embodiments. The elevated track system includes one or more tracks 604, routes, avenues, tubes, ducts, and other such structures (and typically a series of track) that traverse across areas of the shopping facility, and one or more chutes 606, ramps, hoists, elevators, and/or other such access nodes, which are typically distributed across the shopping facility. In some embodiments, one or more of the tracks 604 are elevated above the shelves and other product support structures of the shopping facility. Further, one or more of the tracks may be above a drop down ceiling such that those one or more tracks are not visible from the floor. One or more tracks can be interconnected to establish a network of tracks that can be accessed by multiple motorized transport units allowing the motorized transport units to quickly and easily traverse areas of the shopping facility.
[0087] FIG. 7 illustrates some embodiments of an exemplary elevated track 604 of an elevated track system positioned above one or more shelving units 700, modulars, and other such product support units. In this example, a chute 606 is further illustrated as being cooperated with the elevate track 604 and extending between the elevated track and the sales floor. Referring to at least FIGS. 6 and 7, the central computer system can take advantage of the elevated track system to move motorized transport units through the shopping facility to areas where one or more tasks are to be performed.
[0088] The chutes 606 allow the motorized transport units to access and exit the elevated track system 600. As such, the one or more chutes can be strategically positioned throughout the shopping facility to allow the motorized transport units to easily and quickly access the elevated track system. The positioning of the chutes can further reduce the distance motorized transport units have to travel through the shopping facility to gain access to the elevated track system, which in part reduces traffic in the shopping facility and can improve deployment of the motorized transport units. In some instances, one or more chutes are positioned proximate areas where it is anticipated a relatively large number of motorized transport unit tasks are expected and/or where motorized transport units are to be direct (e.g., near a shopping cart bay where customer retrieve carts, near docking stations, near equipment with which the motorized transport units are configured to cooperate in performing one or more tasks, and other such areas). The chutes are each cooperated with one or more of the tracks and configured to provide a passage for one or more of the motorized transport units between the series of elevated tracks and the floor.
[0089] As illustrated in FIG. 7, in some embodiments, a chute 606 may be positioned at least partially within a shelving unit, end cap 706 (illustrated as partially transparent), or other structure. This allows the chute to be positioned in areas of the shopping facility and taking advantage of the area that is already occupied by the end cap or shelving structure.
This can further limit the use of floor space for the chute that can be utilized for other purposes. Similarly, one or more chutes may be located in areas that are not readily usable, such as in corners or other such areas. In some embodiments, the chutes and the cooperated shelving structure and/or end cap 706 can allow a motorized transport unit to travel under the end cap or shelving unit, through a door in the end cap or shelving unit, and/or allow the motorized transport unit to access and exit the chute. In other implementations, the chutes are not enclosed in a structure allowing motorized transport units ready access to the chutes. Some implementations include doors or other barriers that open in response to a motorized transport unit request and/or instructions from the central computer system. The door prevents children or others from playing with the chutes or otherwise interfering with the use of the chutes.
[0090] The chutes can be substantially any relevant structure that can allow the motorized transport units to move between the floor and the elevated track system. In some implementations one or more chutes are configured such that the motorized transport units move themselves up and down the chutes. For example, one or more channels or tracks can be included one or more and typically at least two channels formed therein to receive corresponding parts of each motorized transport unit that passes through the at least one chute. For example, in some embodiments, the motorized transport units include one or more guide members 208, pegs, hooks, latches, etc., that can cooperate with channels of a chute.
By extending and retracting the motorized transport units can move themselves up and down the chutes. Such movement is further described in U.S. Provisional Application No. 62/175,182, filed June 12, 2015, entitled Method and Apparatus for Transporting a Plurality of Stacked Motorized Transport Units, which is incorporated herein by reference in its entirety. Chutes can be configured in a vertical orientation, angled, helical, switch-back, or other configurations. Similarly, chutes can include ramps that allow the motorized transport units to drive themselves up and down. The chutes may have a circular cross-section, a square cross-section or other shape. Chutes, in some embodiments, may include compressed air cushioning, or other cushioning. The cushioning may allow motorized transport units to travel down the chutes at faster rates than they travel up.
[0091] In some embodiments, one or more chutes may additionally or alternatively include one or more lift systems that move the motorized transport units between the elevated track system and the floor, or help the motorized transport units in moving between the track system and the floor. For example, a chute can include an elevator or dumbwaiter system, a cable system that is cooperated with a motor, one or more conveyors (e.g., that move along a vertical wall and with which the guide members engage), and other such lift systems. For example, the cable system, in some implementations, can include one or more latches, hooks, magnets, other such coupling structure, or a combination of two or more of such structures. When activated the cable system (or other lift system) can raise or lower the motorized transport unit. The lift system can be controlled by the central computers system and/or activated by the motorized transport unit once in position (e.g., by extending to press a switch, lever, etc ).
[0092] One or more transfer systems may be included with the chute and/or cooperated with the chutes to help move the motorized transport unit between the chute and the track. For example, a platform may be moved under the motorized transport unit upon reaching a top of the chute allowing the motorized transport unit to move out of the chute, and similarly be activated when the motorized transport unit attempts to use the chute to exit the elevated track system. An arm may be configured to swing to engage the motorized transport unit and move the motorized transport unit between the track and the chute. A false or movable floor may be cooperated with the chute that is activated when the motorized transport unit is moving between the chute and the track. In other implementations, the motorized transport unit may cooperate with a channel or other structure that allows the motorized transport unit to slide out of the chute. Other systems may be used to move the motorized transport unit between the chute and the track system. The transfer system may be activated by the motorized transport unit (e.g., upon approaching the chute when exiting the track system, pushing a button or moving a lever upon reaching or approaching the top of a chute, etc.), activated by the chute (e.g., based on timing), or may be activated by the central computer system (e.g., based on tracking a location of the motorized transport unit, receiving a communication from an motorized transport unit requesting transfer, etc.).
[0093] The tracks 604 are configured to allow the motorized transport units to travel along the tracks at desired speeds, and often at maximum speed because there is no concern of interfering with customers or bumping into carts or other devices on the floor. Further, in some implementations the central computer system tracks the motorized transport units and can avoid collisions between motorized transport units. In some embodiments, one or more tracks or portions of one or more tracks may be configured to allow a first motorized transport unit traveling on the elevated track to pass a second motorized transport unit traveling on the same elevated track. In some implementations, the track has sufficient width or a portion of a track may have sufficient width to provide effectively two or more lanes, which can be used for opposite directions allowing motorized transport units to pass each other going opposite directs, and/or allow a faster motorized transport unit to pass a slower motorized transport unit traveling in the same direction. One or more track can alternatively or additionally be configured with at least a section that has one or more levels allowing motorized transport units to pass each other (whether traveling in opposite or the same direction). One or more ramps may cooperate different tracks and/or different levels of a track.
[0094] The track system may further include diverter sections, merge areas (e.g., roundabouts, intersections, etc.), multiple lanes (e.g., in high traffic areas), and the like. Multiple lane sections may reduce to a single lane for relatively low traffic areas, areas of limited space, etc. Further, the track system and individual tracks can have inclines, declines and the like (e.g., when there are areas where there is no drop ceiling). One or more of the tracks and/or portions of one or more tracks may be suspended from a roof, support beams, joists, and/or other such structure. Additionally or alternatively, one or more tracks and/or portions of one or more tracks may be supported by beams, joists and/or other such structures. Some embodiments may additionally include tracks and/or chutes that lead to outside areas of the shopping facility (e.g., loading areas, parking structure, parking lots, etc.).
[0095] The tracks may be made from substantially any relevant materials that can support the weight of the motorized transport units intended to utilize the elevated track system. In some implementations, one or more tracks and/or portions of tracks may further include conveyors that move the motorized transport units over those portions of the tracks.
In some embodiments, portions of the track system include vibration and/or noise dampening components (e g., rubber washers, cushioning, rubber on the tracks, insulation dampening, and the like). Further, wind disturbance based on movement of motorized transport units may be taken into consideration (e g., with wind guards, tunnels, etc ). In some implementations, one or more tracks can include gutters or other dirt catches to prevent dirt build-up and/or dirt from dropping down from the tracks. Further, one or more vacuum systems or other cleaning systems may cooperate with and be driven by one or more motorized transport units to clean the tracks and other parts of the track system.
Additionally, some implementations include additional safety features to limit or prevent things falling from the track system (e g., netting, tarps and the like under tracks that extend across areas people are walking.
[0096] One or more sensors, cameras, monitoring equipment, and the like can be cooperated with the elevated track system that can provide the central computer system with information about the elevated track system and the motorized transport units on and traveling along the track system. Such sensors can include distance sensors, RFID sensors, light sources of the location detection system 116, and/or other such sensors. The sensor information is provided to the central computer system to allow the central computer system to track motorized transport units, track the operation of the track system, detect potential problems and the like. Further, the motorized transport units can communicate sensor data detected by sensors of the motorized transport units can be communicated from the motorized transport units to the central computer system providing the central computer system with more information about the state of operation of one or more motorized transport units and the track system.
[0097] FIG. 8 illustrates some embodiments of a portion of an exemplary elevated track 604 of an elevated track system 600 that include one or more staging areas 608. Referring to at least FIGS. 6 and 8, in some embodiments, the track system 600 may be configured to maintain motorized transport units on the track system while motorized transport units are idle and awaiting to be directed to perform a task by the central control system. As such, in some configurations of the elevated track system includes one or more staging areas 608, which can include T-junctions 610, extensions 612, launch pads, other such areas, or a combination of two or more of such areas. The staging areas 608 cooperate with and extend from one or more tracks, and are configured to receive one or more motorized transport units 102 that are idle and/or awaiting instructions from the central computer system. The central computer system can direct the motorized transport unit to move into the staging area. Again, the staging areas allow the one or more motorized transport units to be maintained in the elevated track system without interfering with one or more other motorized transport units as they travel along the series of elevated tracks. The motorized transport units are directed by the central computer system to move from the track to the staging area so that the tracks are freed up to allow other motorized transport units to travel along the tracks. Similarly, in some embodiments, one or more motorized transport units may be positioned or staged within a chute 606, such as on the shopping floor and in the chute as an additional staging area while the motorized transport unit is idle. This allows the motorized transport unit to be out of the way until deployed to perform or assist with a task. The motorized transport unit can be moved out from the chute when another motorized transport unit needs to use the chute.
[0098] The staging areas can be positioned at substantially any location within the elevated track system. Often the staging areas are strategically positioned in areas where relatively large numbers of motorized transport unit tasks are expected, near chutes, or other such locations. In some embodiments, one or more of the elevated staging areas can include one or more charging stations each configured to electrically couple with any one of the multiple motorized transport units and charge a rechargeable battery of the coupled motorized transport unit.
[0099] The use of the staging areas may be controlled by the central computer system based on a first-in-first-out schedule, based on capabilities of the motorized transport units in the staging area and one or more tasks to be performed, based on stored power levels of the motorized transport units, other such factors, or a combination of two or more of such factors. A staging area, in some implementations, may include a conveyor, rotating platform 614, or other such mechanism for moving the motorized transport units through the staging area. When charging stations are incorporated with such staging areas, the charging stations and/or electrical coupling to the charging station may travel with the conveyor, rotating table, or the like.
[00100] In some implementations, a staging area may be configured to allow motorized transport units to move itself into the staging area. Additionally or alternatively, the staging area may vertically stack two or more motorized transport units. For example, a staging area may be configured similarly to a dispensing unit as described in U S. Provisional Application No. 62/175,182, which is incorporated herein by reference in its entirety.
[00101] Again, the central computer controls the movements of the motorized transport units, including directing the motorized transport units to enter or leave the elevated track system, as well as routing the motorized transport units through the elevated track system. In some embodiments, the central computer system communicates routing instructions to the multiple motorized transport units directing the one or more motorized transport units along one or more tracks of the series of elevated tracks in moving to respective desired destinations within the shopping facility. Further, the central computer system typically tracks locations of each of the multiple motorized transport units, and cooperatively coordinates the movements of the multiple motorized transport units as they travel along the series of elevated tracks, chutes and the sales floor. In controlling movement of one or more motorized transport units, the central computer system, in some instances, identifies a location where a motorized transport unit is desired to perform a task, and identifies a relevant motorized transport unit, of the multiple motorized transport units, intended to be directed to the identified location to perform the task. Based on a location of the identified motorized transport unit and the location of the task, the central computer system can determine routing instructions that include directions along one or more of the elevated tracks of the series of elevated tracks that the motorized transport unit is to follow in moving to the identified location of the task. The routing instructions can then be communicated to the motorized transport unit to cause the motorized transport unit to implement the instructions in moving itself along the elevated track system and shopping facility to reach the task location. Again, by utilizing the track system, the motorized transport unit typically can move through the shopping facility quicker (including being parked in a staging area that may be proximate the task location), while reducing traffic on the sales floor.
[00102] The track system provides a system to in part support customer service at a shopping facility. The central computer system can identify locations where motorized transport units are desired to perform respective tasks, and identify one or more motorized transport units that can be directed to the one or more identified locations to perform the tasks. Based on the location of a motorized transport unit and the location where the task is to be initiated, the central computer system can further determine routing instructions that include directions along one or more tracks of the series of elevated tracks distributed over at least a portion of the sales floor of the shopping facility such that the tracks do not interfere with customers movement through the sales floor. The central computers system can cause the routing instructions to be communicated to the one or more motorized transport units. In implementing the routing instructions, the motorized transport unit may travel over at least a portion of one or more tracks in moving to the identified location of the task.
[00103] FIG. 9 illustrates a simplified flow diagram of an exemplary process 900 of routing motorized transport units through a shopping facility, which can include utilizing the elevated track system 600 when relevant, in accordance with some embodiments. In step 902, the central computer system instructs multiple motorized transport units to access the elevated track system 600. In some embodiments, the instructions to the multiple motorized transport units can include instructing the multiple motorized transport units to access at least one of one or more chutes that are each cooperated with one of the elevated tracks. Again, each of the one or more chutes provides a passage for one or more of the motorized transport units between the series of elevated tracks and the sales floor. As described above, in some embodiments, one or more chutes may be vertical chutes, while in other implementations one or more chutes may be angled (e.g., including one or more ramps, which may include a spiral configuration, switch backs, be a straight ramp, or other configuration). Further, in some embodiments one of the one or more chutes are vertical chutes with at least two channels formed therein to receive a corresponding part of each motorized transport unit that passes through the at least one chute.
[00104] In step 904, further instructions are issued directing the multiple motorized transport units to travel along the series of elevated tracks in traversing at least portions of the shopping facility. In some instances, the instruction to the multiple motorized transport units to travel along the series of elevated tracks may cause two or more motorized transport units to pass each other on a single track. Accordingly, the routing instructions may include instructing at least a first and second motorized transport units to travel along at least a first elevated track having a width such that the first motorized transport unit traveling on the first elevated track passes the second motorized transport unit traveling on the first elevated track.
[00105] In some instances, the central computer system may issue instructions to one or more of the multiple motorized transport units to enter and/or exit one or more staging areas of the elevated track system that extends from a track of the series of elevated tracks. Again, the staging areas are configured to receive one or more motorized transport units that are idle and awaiting instructions from the central computer system and allow the one or more motorized transport units to be maintained in the elevated track system without interfering with one or more other motorized transport units as they travel along at least the one track of the series of elevated tracks. One or more of the motorized transport units may further be instructed to electrically couple with a charging station cooperated with a staging area and configured to electrically couple with any one of the multiple motorized transport units and charge a rechargeable battery of the coupled motorized transport unit.
[00106] The central computer system can take advantage of the elevated track system and communicate routing instructions to the multiple motorized transport units directing one or more motorized transport units along one or more tracks of the series of elevated tracks in moving to respective desired destinations within the shopping facility. The locations of each of the multiple motorized transport units can be tracked by the central computer system.
Using the location information, the central computer system can further cooperatively coordinate the movements of the multiple motorized transport units as they travel along the series of elevated tracks and the sales floor. Further, the central computer system can identify a location where a motorized transport unit is desired to perform a task. A first motorized transport unit, of the multiple motorized transport units, can be identified that is intended to be directed to the identified location to perform the task. Routing instructions can be determined by the central computer system that include directions along one or more elevated tracks of the series of elevated tracks that the first motorized transport unit is to follow in moving to the identified location of the task. These routing instructions can then be communicated to the first motorized transport unit to cause the first motorized transport unit to implement the instructions and move along at least a portion of the elevated track system to reach the task location.
[00107] The dispatching of one or more motorized transport units may be delayed causing them to be ineffective and inefficient due to distances to be traveled, human traffic within a shopping facility, the speed of travel through a shopping facility, and other such conditions. Similarly, the stocking of shelves with pallets and other objects placed in potential routes of travel through a sales floor may also present a blocked aisle causing an inefficient route to be used to complete an activity. The track system, however, can include one or more tracks, which may be positioned overhead, with one or more chutes cooperated with the tracks to enable motorized transport units to quickly move from one part of a shopping facility to the other. The chutes can extend from a track (and often through a ceiling) to the floor. In some implementations the chute is configured such that a bottom of the chute is a few inches above the top of a motorized transport unit and/or include an opening, door or the like through which the motorized transport unit can exit. The motorized transport unit can enter the track system from a chute. When rising up the chute, in some instances, the motorized transport unit uses a twisting and lock hydraulics to climb through the chute (e.g., using one or more channels). The tracks can run, in some instances, in the rafters of the facility. The track system can include one or more dispensing bays and/or staging areas at the front and/or back of the shopping facility, or anywhere as needed and where space is available. Staging areas can also be included at ground level, such as proximate one or more chutes in a back storage area of the shopping facility.
[00108] The track system allows motorized transport units to quickly be transported without interfering with customers. As the shopping facility may need multiple places to quickly deploy a motorized transport unit, chutes may be placed anywhere in the shopping facility. One or more tracks may be configured and positioned to allow the motorized transport units to travel in either direction at the same time. Further, multiple chutes can be positioned adjacent to each other and/or a single chute can be configured with multiple passages to allow one motorized transport unit to go up as one motorized transport unit goes down.
[00109] The track system, in part, provides speedway type tracks that assist with motorized transport units moving quickly from one part of a shopping facility to another. It further enables quick response times of motorized transport units to and from customer requests and other tasks. For example, when one or more motorized transport units are needed to collect or clean up movable item containers (e.g., at a front of the shopping facility and/or in a parking lot), and the motorized transport units are located in the backroom, the motorized transport units can be directed to use the track system to quickly get to the front of the shopping facility to perform this task. The tracking system enables motorized transport units to move around the shopping facility effectively without hindering traffic on the sales floor. Along with this the track system also improves estimated time of arrivals on customer assistance. This will enable customers to request motorized transport units via mobile device, help button, by asking an associate, and the like, and have the motorized transport unit at their side in a relatively short time (e.g., a matter of seconds in some instances). Further, the track system also assists with keeping the sales floor clear of multiple motorized transport units traveling to and from tasks. This can further reduce or solve a problem of overcrowding the sales floor with multiple motorized transport units. The track system can allow and/or transport motorized transport units, and/or special motorized transport units, and in some instances, equipment utilized by the motorized transport units (e.g., cleaning systems, ground treatment systems, cart retrieval motorized transport units, motorized transport units with enhanced power capabilities, etc.).
[00110] As described above, the chutes cooperate with one or more tracks and allow motorized transport units to move between the ground and the track system. Chutes may be embedded alongside or within other sales floor components such as select displays, end cap units, racks, shelving, and the like. Additionally or alternatively, chutes may be positioned in places that are under-utilized.
[00111] In some implementations, one or more tracks and chutes can be designed to be capable of accommodating various drone models or associated loads such as small lockers, some types of movable item containers, cleaning devices and/or systems, and other such systems. For example, one or more tracks to a lawn and garden patio area of a shopping facility can be configured to accommodate a sweeper drone. Further, some embodiments include staging areas and/or rapid deployment launch pads that are deployed throughout the track system allowing decentralized storage of available motorized transport units. This can improve three-dimensional space optimization minimizing time from request to arrival. The staging areas can, in some implementations, include one or more extended segments of track located either at an endpoint or at a strategically placed “T” junction”. One or more charging stations may further be available at these staging locations to maintain readiness.

In some embodiments, a track system comprises: an elevated track system comprising a series of elevated tracks that are positioned elevated above a sales floor and products distributed over at least a portion of the sales floor of a shopping facility, and configured such that multiple motorized transport units travel along the series of elevated tracks in traversing at least portions of the shopping facility.
