Description

The present invention relates to a floating moving table that can be floated and used as a table on which various articles are placed in the vicinity of a user.

For example, when a worker replaces a fluorescent lamp such as a fluorescent tube of a lighting fixture installed on the ceiling by himself, the worker has conventionally had to go up to a stepping stone and replace it. Remove the fluorescent tube or the like from the fluorescent lighting fixture, get off the platform once, and place the old fluorescent tube (fluorescent lamp or fluorescent lamp) or the like in any place. Then, after that, the worker takes a new part such as a fluorescent tube and goes up to the stepping stone again, and attaches the new part or the like to the fluorescent lamp fixture. Therefore, the worker had to repeatedly go up and down the platform, which was troublesome.

If there is an assistant, the worker can hand over the old fluorescent tube, etc., and also hand over the new fluorescent tube, etc., so the worker can replace it without having to repeatedly go up and down the platform. You can work. However, since there is not always an assister, the above-mentioned problem remains.

Therefore, in addition to the platform, a platform is prepared, and old fluorescent tubes and new fluorescent tubes to be replaced are placed on the platform to minimize the number of times the operator goes up and down the platform. Can be done.

However, it is desirable that such a mounting table has a height corresponding to the height of the ceiling and an appropriate height for the operator, but there are few mounting tables with such a height. .. For this reason, even when using a mounting table, when the mounting table is too low, the operator can use the platform to place an old fluorescent tube to be replaced or to pick up a new fluorescent tube. If you do not go down halfway and climb again, it will be difficult to work without damaging the fluorescent tube, and there is also the problem that work efficiency will be poor and the work will be troublesome.

As a solution to this problem, for example, it is conceivable to use a mounting table that can be raised and lowered as described in Patent Document 1 (Japanese Patent Laid-Open No. 2006-20866). That is, this is a method in which the height of the elevating mounting table of Patent Document 1 is adjusted in advance to a height that the operator thinks is appropriate for him / herself.

However, the method of using the elevating platform described in Patent Document 1 requires an installation space for the platform in addition to the installation space for the platform for workers, and in a situation where such an installation space cannot be secured. Not available. In addition, it is necessary to adjust the height of the mounting table to the optimum height in advance according to the height of the ceiling and the operator, but the height adjustment in advance is to actually get on the stepping stone and adjust the mounting table. It is relatively troublesome to adjust while checking the height of the. Further, when the work is continuously performed, the worker has to move not only the stepping stone but also the mounting table, which is troublesome.

In addition, for example, when cooking in the kitchen, the person who cooks usually prepares ingredients such as vegetables and meat, and a place where cooking utensils such as a stove and an oven are located is a predetermined place. Do cooking work while moving. Furthermore, if the place where cooking containers such as pots and frying pans are placed and the place where seasonings are placed are also decided, the place where ingredients are prepared and the place where cooking utensils are placed and their places. You also need to move between. Further, for example, when trying to cook while looking at a recipe book or the like, in addition to the above-mentioned plurality of places, the work of looking at the recipe book or the like to confirm the cooking work is further added.

However, the place where the ingredients are prepared and the place where there are cooking utensils such as stoves and ovens cannot be moved, so it is unavoidable, but cooking containers such as pots and frying pans, seasonings, and recipe books are not available. It is also possible to move on a pedestal, and some cooks do so.

In this case, if the mounting table is equipped with a movable wheel or the like and is movable, the cook can move it appropriately, but if both hands of the cook are blocked. Cannot move the platform with the movement of the cook. For this reason, even if there is a movable mounting table, it is difficult to properly move the mounting table according to the work of the cook as the cook moves.

In addition, at a construction site, a worker who is working at a high place wants to receive necessary tools and materials at a low place, or is working at a remote place even at the same high place. In the past, when borrowing tools or receiving materials from a worker, another worker throws the tools or materials to the worker who is present at the requested height, or bothers to request it. They move to a high place where the workers who have done so are and hand them over.

However, if a worker at a high place fails to receive the thrown tools and materials, those tools and materials will fall, which is extremely dangerous and will also be received by the worker at a high place. Due to his actions, he often loses his balance and falls. In addition, if another worker moves to a high place where the requesting worker is and hands it over, the other worker is forced to take actions other than the original work and is inefficient. There is a problem.

Japanese Unexamined Patent Publication No. 2006-20866

As described above, conventionally, it was possible to reduce the work load by using the mounting table, but the above-mentioned problems remained. In addition, there were environments such as construction sites where the mounting table could not be used.

In view of the above points, an object of the present invention is to provide a floating moving table capable of eliminating the above-mentioned problems.

In order to solve the above problems, the present invention

To do.

Levitation moving base of the present invention configured as described above is provided with the image information of Ru is placed on the stage article, a storage means for storing in association with the weight of the article.

The user can place an article on the pedestal of the levitation moving table and take out the article placed on the pedestal. In this case, the height position of the mounting table remains unchanged and changes according to the weight of the article.

However, in the present invention, when the control unit predicts by image recognition that the article stored in the storage means is about to be placed on the mounting table, or when the article stored in the storage means is stored. When it is predicted by image recognition that it is about to be taken out from the mounting table, the weight of the article stored corresponding to the storage means is recognized, and the article is placed on the mounting table based on the recognized weight. It is corrected so that the amount of lowering of the mounting table according to the weight of the article when it is lifted is reduced, or the amount of raising of the mounting table according to the weight of the article when the article is taken out from the mounting table is reduced .

Therefore, even if an article is placed on the mounting table of the floating moving table or the article placed on the mounting table is taken out, the height position of the mounting table is optimally corrected, so that the user can use it. The article can be placed on the loading platform at the optimum height position, and the article can be taken out from the loading platform.

In this example, the mounting table 9 has an opening at the upper side and has a U-shaped cross section in a basket shape. The mounting table 9 has holes formed in the bottom surface and side surfaces of the basket in a mesh shape so as not to affect the air flow generated by the rotation of the rotor blades 52A, 52B, 52C, and 52D as much as possible. ing.

Although not shown, an LED (Light Emitting Diode) light is provided on the upper surface of the housing 6 so that the article placed on the mounting table 9 can be illuminated and the work can be performed even in a dark place. ..

A drive control device unit 10 is provided in the housing 6. FIG. 2 is a block diagram showing a configuration example of the drive control device unit 10 in the levitation moving table 1 of this embodiment. In FIG. 2, the battery is omitted.

As shown in FIG. 2, the drive control device unit 10 in this embodiment refers to the control unit 101 composed of a microphone (abbreviated as a microphone in FIG. 2) through the system bus 100, the aerial flight drive unit 102, and the gyro sensor. 103, geomagnetic sensor 104, gravity sensor 105, altitude sensor 106, obstacle sensor 107, temperature sensor 108, weight sensor 109, moving space memory 110, current position detection unit 111, flight drive signal generation unit 112, position / orientation control signal generation Unit 113, cameras CM1 to CM6, omnidirectional microphone (abbreviated as omnidirectional microphone in FIG. 2) MC, image recognition unit 114, voice recognition unit 115, alarm notification unit 116, learning unit 117, prediction unit 118, operation unit. Each of 119 is connected and configured. The control unit 101 constitutes a main control means for controlling the entire levitation moving table 1.

The air flight drive unit 102 supplies drive control signals to the motor drive units 51A, 51B, 51C, and 51D of the rotary blade mechanisms 5A, 5B, 5C, and 5D of the air flight mechanism unit 2 according to the control of the control unit 101. To do.

The gyro sensor 103 detects a change in acceleration of the levitation moving table 1 during flight, and is used to detect the flight traveling direction of the levitation moving table 1, its speed, and its attitude. The geomagnetic sensor 104 is used to detect in which direction the levitation mobile platform 1 is facing north, south, east, and west, and in which direction the levitation mobile platform 1 is flying.

The gravity sensor 105 is for detecting the direction of gravity (vertical direction), and is composed of, for example, an acceleration sensor, and is used for controlling the bottom surface of the mounting table 9 of the levitation moving table 1 to be kept horizontal.

The altitude sensor 106 is for detecting the altitude at which the levitation moving table 1 is located at that time point, and includes, for example, a barometric pressure sensor.

The obstacle sensor 107 emits light, infrared rays, ultrasonic waves, or the like to detect reflected waves from obstacles such as a follower or a wall, thereby detecting the presence of obstacles and light, infrared rays, or the like. Alternatively, it is possible to detect the time from the emission of ultrasonic waves to the reception of the reflected wave, and calculate the distance to the detected obstacle from that time. In this embodiment, the obstacle sensor 107 is a follower, a person other than the follower, an animal such as a pet, a wall, a chest of drawers, a bed, or a desk in the indoor or outdoor space where the floating moving table 1 is used. , Used to be controlled to avoid collisions with obstacles such as garden trees.

Further, in this embodiment, the obstacle sensor 107 is also used when the levitation moving table 1 is hovered controlled while maintaining a predetermined distance, for example, about 40 cm from the tracking target person. At this time, the captured image information from the camera that captures the tracking target person among the cameras CM1 to CM6 is also used.

The temperature sensor 108 is used to detect a high temperature atmosphere in order to keep the floating moving table 1 away from an ignited stove or the like, assuming that the floating moving table 1 is used in a kitchen. When controlling the levitation moving table 1 so as not to come close to the stove in the ignition state, the camera in the cameras CM1 to CM6 also uses the photographed image information of the ignition state of the stove. is there.

The weight sensor 109 is for detecting the weight of the article placed on the mounting table 9 and detecting the weight change after the article is picked up from the mounting table 9. In this embodiment, the weight of the article detected by the weight sensor 109 when the article is placed on the mounting table 9 is the weight of the article mounted on the mounting table 9 taken by the camera CM1. It is stored in association with the placement position on the bottom surface. In this embodiment, as will be described later, the hovering height position is controlled according to the weight of the article detected by the weight sensor 109.

The moving space memory 110 stores spatial information about the room in which the floating moving table 1 is used. An application program for panoramic photography (for example, Photosynth) is stored in the memory of the control unit 101 of the floating moving table 1 of this embodiment, and the floating moving table 1 flies in the room where it is used in advance. , All or part of the cameras CM1 to CM6 is used to photograph the room in a range of 360 degrees. Then, the control unit 101 uses an application program for panoramic photography to generate indoor 3D image information from the captured image information, and stores the generated 3D image information in the moving space memory 110.

In this case, the moving space memory 110 also stores information on the length, width, and height of the kitchen or other room used in advance. Further, structural information of the room to be used such as beams, pipe spaces, and columns may be stored in advance.

The current position detection unit 111 includes, for example, a GPS (Global Positioning System) receiver, and detects the latitude, longitude, and altitude of the current position of the floating mobile platform 1. In order to obtain more accurate location information, the current location may be detected using radio waves from a mobile phone base station or radio waves from an access point for Wi-Fi (Wireless Fidelity®) communication. .. Further, all or a part of the cameras CM1 to CM6 is used to photograph the surroundings of the floating moving table 1, and the photographed image information is compared with the 3D image information stored in the moving space memory 110 for image recognition. As a result, the relative position in the 3D image space may be grasped and the current position may be detected. In order to detect the current position after movement, the current position detection unit 111 also uses the gyro sensor 103, the geomagnetic sensor 104, and the altitude sensor 106.

The flight drive signal generation unit 112 executes the following processing operations under the control of the control unit 101.

First, when starting a levitation flight based on an activation command from the control unit 101, first, a flight drive signal for finding a follower is generated. In this case, when the moving space in which the floating moving table 1 is used is the moving space stored in the moving space memory 110, the position information of the current position detected by the current position detecting unit 111 and the moving space memory From the information of the moving space stored in 110, the moving direction and the moving distance are calculated in order to generate a flight drive signal for moving so as to search for the follow-up target person.

Then, the flight drive signal generation unit 112 uses information such as the gyro sensor 103, the geomagnetic sensor 104, the gravity sensor 105, the altitude sensor 106, the obstacle sensor 107, and the temperature sensor 108 based on the calculated direction and distance, and further. , While referring to the captured images from the cameras CM1 to CM6, generate a flight drive signal for moving so as to detect the follow-up target person.

This flight drive signal is composed of a signal for driving each of the motor drive units 51A to 51D of the four rotor mechanisms 5A to 5D. The generated flight drive signal is supplied to each of the motor drive units 51A to 51D of the air flight mechanism unit 2 through the flight drive unit 102. In response to this flight drive signal, the aerial flight mechanism unit 2 rotationally drives each of the rotary blades 52A to 52D, and moves by aerial flight so as to detect the follower.

When the levitation moving table 1 detects the follow target person, the flight drive signal generation unit 112 follows the control of the control unit 101 with reference to a specific physical part of the follow target person, in this example, the position of the lower jaw of the follow target person. At the height position, a flight drive signal for hovering while maintaining the horizontal state of the mounting table 9 at a predetermined distance from the follower is generated, and the flight mechanism unit is passed through the air flight drive unit 102. To supply to 2. The position / attitude control signal generation unit 113 generates a signal for controlling the height position to hover, as will be described later.

Then, when the follow-up target person moves, the flight drive signal generation unit 112 generates a flight drive signal to follow the movement of the follow-up target person according to the control of the control unit 101, and the flight drive signal generation unit 102 generates a flight drive signal to follow the movement of the follow-up target person. It is supplied to the aerial flight mechanism unit 2 through. At the time of this movement, the floating moving table 1 uses information such as the gyro sensor 103, the geomagnetic sensor 104, the gravity sensor 105, the altitude sensor 106, the obstacle sensor 107, and the temperature sensor 108, and further, from the cameras CM1 to CM6. While referring to the photographed image of the above, avoiding collision with obstacles and avoiding places where the vehicle should not fly, the following movement is performed according to the movement of the tracking target person. Therefore, during this movement, the levitation moving table 1 does not consider the holding of the height position and the strict separation from the tracking target by a predetermined distance.

Then, when the follow-up target person stops moving, the levitation moving table 1 refers to the above-mentioned relationship with the follow-up target person, that is, a state separated from the follow-up target person by a predetermined distance and the position of the lower jaw of the follow-up target person. A flight drive signal for hovering at the set height position is generated and supplied to the air flight mechanism unit 2 through the air flight drive unit 102.

The flight drive signal generation unit 112 may move or hover while avoiding the sky above a lit stove based on the sensor output of the temperature sensor 108, as described above. Generates flight drive signals, such as hovering.

Then, when the end command (landing command) is issued from the control unit 101, the flight drive signal generation unit 112 releases the above-mentioned relationship with the follow-up target person, and is at a predetermined location or in the vicinity of the current position. , A flight drive signal for moving and landing is generated at an arbitrary place where landing is possible, and is supplied to the air flight mechanism unit 2 through the air flight drive unit 102.

Under the control of the control unit 101, the position / attitude control signal generation unit 113 is based on the captured images of the gyro sensor 103, the geomagnetic sensor 104, the gravity sensor 105, the altitude sensor 106, the weight sensor 109, and the cameras CM1 to CM6. A signal is generated for controlling the height position of the floating moving table 1 and controlling the horizontal state of the bottom surface of the mounting table 9.

When the position / attitude control signal generation unit 113 detects that an article is placed on the mounting table 9 of the floating moving table 1 from the captured images of the cameras CM1 to CM5, the position / attitude control signal generation unit 113 is hovering under the control of the control unit 101. The sensor output of the gravity sensor 105 is used to generate an attitude control signal to keep the bottom surface of the platform 9 horizontal, not only when ringing but also when moving in levitation. To do.

Then, the position / orientation control signal generation unit 113 detects the height position of the lower jaw of the face image of the follower captured by any of the cameras CM2 to CM5 in this example as an example of the reference height position. Then, after temporarily hovering to that height position, a position / attitude control signal for hovering is generated at a height position, for example, 20 cm below the height position. As will be described later, this height position can be adjusted by an action (gesture) by the follower or a voice command.

The hovering position in the horizontal direction with the follower as the center is diagonally forward to the left or diagonally to the right of the follower. However, if it interferes with the original work of the follower (fluorescent tube replacement work or cooking work), the position should be such that it does not interfere.

The position / attitude control signal generation unit 113 also has the hovering height position described above when the follower places the article on the mounting table 9 of the floating moving table 1 or takes out the article from the mounting table 9. The position / attitude control signal for correction is generated based on the control of the control unit 101.

Each of the cameras CM1 to CM6 outputs the captured image information of the moving image to the system bus 100. Identification information for identifying which camera the photographed image information is from is added to the photographed image information transmitted from each of the cameras CM1 to CM6 to the system bus 100. The captured image information from each of the cameras CM1 to CM6 may be captured image information of a still image at a predetermined time interval, for example, 0.5 second interval, instead of the captured image information of a moving image.

The omnidirectional microphone MC is for collecting the voice information of the command word issued by the follower. Although not shown, in the floating moving table 1 of this embodiment, only the acoustic information in the human conversation voice band (for example, 200 Hz to 4 KHz) among the acoustic information picked up by the omnidirectional microphone MC is available. It is sent to the system bus 100 through a bandpass filter.

It is also possible to use the sound of the follower's hand clapping or finger ringing, which is picked up by the omnidirectional microphone MC. In this case, the levitation moving table 1 flies and moves in response to the sound of the caller or the follower clapping the hand or the sound of the finger ringing pickled by the omnidirectional microphone MC. In general, the sound of clapping hands has a frequency power peak of 0 to 2 KHz, and the sound of ringing a finger has a peak of frequency power of 2 to 4 KHz. Therefore, the band is sent to the system bus 100 through a bandpass filter, and the sound of clapping hands. Or the sound of ringing a finger may be recognized.

The image recognition unit 114 includes an image memory 114M for storing image information of an image recognition target to be recognized from the captured image information from the cameras CM1 to CM6. In this embodiment, the levitation moving table 1 is configured so that the facial images of one or more persons can be registered in advance in the registrant storage area of the image memory 114M as the following persons to be followed and moved. ..

Then, the levitation mobile platform 1 of this embodiment automatically creates a list of follow-up target persons in which facial images are registered, and prior to the start of use of the levitation mobile platform 1, the list of follow-up target persons is displayed. It is displayed on the display unit (not shown). The user can select and specify the follow-up target person of the levitation moving table 1 from the list of follow-up target persons through the operation unit 119. Instead of providing a display unit, a plurality of buttons that can be associated with each follow-up target person are provided, and the follow-up target person is selected by operating one of the plurality of buttons. You can also.

Further, in this embodiment, the levitation moving table 1 can be started without selecting the follow-up target person. In that case, a person in the vicinity of the levitation moving table 1 is determined as the follow-up target person, and the cameras CM2 and 2 A face image of the follow-up target person is photographed by any of CM5 and stored in the follow-up target person storage area of the image memory 114M, and thereafter, it is stored in the follow-up target person storage area until an end command is given. The follow-up movement is controlled as described above by using the face image of the person who is following as the face image of the follow-up target person.

Further, in this embodiment, the follower, depending on the action (gesture), causes the levitation moving table 1 to "lower the height a little", "raise the height a little", and "rotate the mounting table 9". "Change the hovering position (centered on the follower) to the right" and "Change the hovering position (centered on the follower) to the left" can be controlled and commanded. There is. The control command storage area is provided in the image memory 114M, and the control command storage area stores information on correspondence between the above-mentioned control command and an image of an action (gesture) corresponding to the control command. Although not shown, the light touch of the levitation moving table 1 by the follower is detected by a capacitive touch sensor or the like, and the follower moves up and down or left and right depending on the touch position and pressure direction. It may be possible to control it.

The control unit 101 monitors the captured image information of the cameras CM1 to CM6, and the image recognition unit 114 has the same behavior (or an approximation) as the behavior stored in the control command storage area of the image memory 114M by the follower. Try to determine whether or not the action) has been done. Then, when the control unit 101 determines that the follower has performed the same action (or an approximate action) as the action of the control command stored in the control command storage area of the image memory 114M, the control unit 101 corresponds to the action. A control command is acquired from the control command storage area of the image memory 114M, and a control signal is supplied to the aerial flight mechanism unit 2 so that the floating moving table 1 performs an operation according to the acquired control command.

Further, in this embodiment, the levitation moving table 1 can be given the above-mentioned control command by the voice emitted by the follow-up target person.

The voice recognition unit 115 is for recognizing a voice control command by the follow-up target person, and is a voice memory 115M that stores correspondence information between the above-mentioned control command and the voice information of the above phrase corresponding thereto. It has.

The control unit 101 monitors the voice information picked up by the omnidirectional microphone MC, and the voice recognition unit 115 monitors the voice phrase of the control command stored in the control command storage area of the voice memory 115M by the follower. Try to determine if the same phrase (or similar phrase) was spoken. Then, when the control unit 101 determines that the follower has uttered the same voice phrase (or a similar phrase) as the control command stored in the control command storage area of the voice memory 115M, the control unit 101 corresponds to the voice phrase. The control command to be performed is acquired from the control command storage area of the image memory 114M, and a control signal is supplied to the aerial flight mechanism unit 2 so that the floating moving table 1 performs an operation according to the acquired control command.

In this case, when the control unit 101 is instructed to "lower the height a little", the control unit 101 is instructed to lower the height by, for example, 2 cm from the current height position, and to "increase the height a little". At that time, it is controlled to be raised by, for example, 2 cm from the current height position. Further, when there is a command to "rotate the mounting table 9", the control unit 101 keeps the horizontal state of the mounting table 9 and, for example, 90 degrees to 180 degrees around the center position of the mounting table 9. Control to rotate. When the mounting table 9 itself has a rotating mechanism (not shown), the mounting table 9 is controlled to rotate, and the mounting table 9 does not rotate and is fixed to the housing 6 of the floating moving table 1. If so, the levitation moving table 1 itself controls the position of the mounting table 9 by controlling the position such as rotation.

In addition, when there is a command to "change the hovering position (centered on the follower) to the right" or "change the hovering position (centered on the follower) to the left", the control unit The 101 controls the left and right positions of the levitation moving table 1 with respect to the follower to be changed to a side different from the current state. Other voice commands may include "come a little", "here", "away", and the like.

The alarm notification unit 116 follows when the weight of the article placed on the mounting table 9 of the floating moving table 1 is such that the hovering cannot be held by the floating moving table 1 (overweight). The subject is notified to that effect through a speaker (not shown) as a voice alarm such as a buzzer sound. Alternatively, a voice message such as "overweight" may be emitted by a speaker as a voice alarm to notify the user. Whether the weight is over or not is determined based on the weight detected by the weight sensor 109. Even in a slightly light state before the weight is over, a voice alarm may be used to notify that further placement is dangerous.

Further, the image recognition unit 114 recognized that the image information of the article which is overweight was registered in advance in the image memory 114M and the registered article was about to be placed on the mounting table 9. Sometimes, even if the alarm notification unit 116 emits a voice message such as "It is overweight" or "There is a danger of overweight" by the speaker as a voice alarm before mounting it. Good.

Further, the image recognition unit 114 recognized that the image information of the drink or liquid article was registered in advance in the image memory 114M and the registered article was about to be placed on the mounting table 9. Occasionally, the alarm notification unit 116 may use a speaker to emit a voice message such as "There is a risk of liquid spilling." As a voice alarm before the placement.

The alarm notification unit 116 may light or blink an indicator (not shown), a display unit (not shown), or display a message.

The learning unit 117 includes a history memory 117M that stores information (history information) of the past usage history of the floating mobile table 1. In this case, the history information consists of image information of the follow-up target person taken by the cameras CM1 to CM6, and is a history memory together with the position information of the place of use and the face image information of the follow-up target person using the floating moving table 1. It is stored in 117M. When the tracking target person is a user registered in the image memory 114M, the identification information of the registered tracking target person is also stored.

As a result, when a registered user is selected as the follow-up target person at the start of use of the levitation mobile platform 1, the information of the past usage history by the follow-up target person can be referred to in the learning unit 117. Further, when the user registered as the follow-up target person is not selected at the start of using the floating moving table 1, when the follow-up target person is recognized by any of the cameras CM2 to CM5, the face image and history thereof. When the face image is matched with the face image stored in the memory 117M, the past history information of the follow-up target person of the matched face image is referred to in the learning unit 117.

The learning unit 117 learns the usability of the follow-up target person by learning the past usage history of the follow-up target person stored in the history memory 117M, and based on the learning result, the levitation moving table 1 is used. Control. For example, if the dominant hand of the follow-up target person is found as a result of referring to the past usage history, the levitation moving table 1 is set to hover on the dominant hand side of the follow-up target person. Further, for example, in cooking work in the kitchen, after cutting ingredients such as vegetables, there is a tendency to put them on a plate and place them on the mounting table 9 of the floating moving table 1 with the non-dominant hand. When such a situation is predicted from the captured image information of any of the cameras CM2 to CM5 at the time of use, the levitation moving table 1 moves ahead of time to the side opposite to the dominant hand. Then hover and wait.

The prediction unit 118 controls the levitation mobile pedestal 1 according to a matter predicted from the captured image information of any of the cameras CM2 to CM5 when the levitation mobile pedestal 1 is used.

That is, when the levitation moving table 1 is hovering in the air and it is predicted that an article will be placed on the loading table 9 by the follower, the descent due to the weight of the placed article is minimized. Control so that the amount of descent is sufficient. In this case, the weight measured by the weight sensor 109 of the article mounted on the levitation moving table 1 is stored in the history memory 117M together with the image information of the article taken by the cameras CM1 to CM6, and the storage thereof is stored. When the same article as the article is about to be placed on the floating moving table 1, the weight of the article is known, so that the floating moving table 1 does not lower as much as possible even if the article is placed. It can be easily corrected.

Further, as described above, when an article is picked up from the floating moving table 1, it can be recognized as a weight stored in association with the mounting position on the bottom surface of the picked-up article mounting table 9, so that it can be predicted. Based on the certified weight, the unit 118 controls the levitation moving table 1 so that the amount of lift is as small as possible.

When the next action can be predicted from the action of the follow-up user, the prediction unit 118 moves the levitation moving table 1 to the optimum hovering position according to the predicted action, and the action of the follow-up target person. To be able to perform optimal control ahead of time.

The operation unit 119 is for the user to input the flight start activation of the levitation mobile table 1, the creation of the moving space information, the storage instruction to the moving space memory 110, and other operation instructions. Further, in the floating moving table 1 of this embodiment, the user can set a mode according to the place of use and the purpose of use of the past history stored in the history memory 117M. For example, if the place of use is the kitchen, the kitchen mode, if the purpose of use is to replace the fluorescent tube, the fluorescent tube exchange mode, if the purpose of use is to dry the laundry, the laundry drying mode, if the purpose of use is to take in the laundry, , Laundry capture mode, etc. can be set.

Then, the floating moving table 1 of this embodiment automatically creates a list of set modes, and displays the list of the modes on a display unit (not shown) prior to the start of use of the floating moving table 1. To do. From the list of this mode, the user can select through the operation unit 119 according to the place and purpose for starting the use. Instead of providing a display unit, it is also possible to provide a plurality of buttons that can be associated with each mode and select a mode by operating any of the plurality of buttons. Then, when the mode is selected through the operation unit 119, the learning unit 117 uses the learning result obtained by referring to the history information corresponding to the mode for the control of the levitation moving table 1.

In FIG. 2, the control unit 101 of the flight drive signal generation unit 112, the position / attitude control signal generation unit 113, the image recognition unit 114, the voice recognition unit 115, the alarm notification unit 116, the learning unit 117, and the prediction unit 118 are It can also be realized as a software processing function.

[Operation example of floating mobile table 1]
Next, a processing operation example of the floating moving table 1 of the first embodiment will be described with reference to the flowcharts of FIGS. 3 and 4. In the following description, the control unit 101 is a flight drive signal generation unit 112, a position / attitude control signal generation unit 113, an image recognition unit 114, a voice recognition unit 115, an alarm notification unit 116, a learning unit 117, and a prediction unit 118. The case where the processing function of each part of the above is realized as a software processing function will be described. It should be noted that the loading table 9 of the levitation moving table 1 may be loaded with articles necessary for work before the start of use, or may be loaded with articles necessary for work after the start of use.

First, the control unit 101 determines whether or not a start command has been received (step S101). This start command may be input by an operation through the operation unit 119, or may be a voice command or an action (gesture) command. The user who is the follower can select and set any of the kitchen mode, the fluorescent tube replacement mode, the laundry drying mode, the laundry taking-in mode, and the like described above before issuing the start command. In addition, the user who becomes the follow-up target person can select and set himself / herself as the follow-up target person when his / her face image is registered.

When it is determined in step S101 that the start command has not been received, the control unit 101 repeats the step S101 and waits for the start command to be received. Then, when it is determined in step S101 that the start command has been received, the control unit 101 controls the air flight mechanism unit 2, takes off, moves upward, and searches for the follow-up target person (step S102).

Then, the control unit 101 determines whether or not the follow-up target person can be certified while performing the search flight of the follow-up target person (step S103), and when it is determined that the follow-up target person cannot be certified, the step Returning to S102, the search movement of the follow target person is continued. When it is determined in step S103 that the follow-up target person can be certified, the control unit 101 determines that the follow-up target person can be recognized, and as described above, the control unit 101 refers to the height at a position separated from the certified follow-up target person by a predetermined distance. As an example, hovering is performed while keeping the mounting table 9 horizontal at a height position 20 cm below the position of the lower jaw of the follow-up target person (step S104).

In this case, if the follow-up target person is not selected prior to the start command, the control unit 101 searches for and certifies a user existing in the vicinity as the follow-up target person. Then, the face image of the follow-up target person photographed and certified by any one or a plurality of cameras CM2 to CM5 is stored in the temporary storage area of the image memory 114M as the follow-up target person of the time. Further, when the follow-up target person is selected and specified prior to the start command, the control unit 101 selects a follow-up target person that matches the face image stored in the image memory 114M of the selected follow-up target person. Search and certify. Then, the face image stored in the image memory 114M of the selected follow-up target person is stored in the temporary storage area of the image memory 114M as the follow-up target person of the time. The control unit 101 always grasps a person who matches the face image stored in the temporary storage area of the image memory 114M as a tracking target person in the following movement.

After step S104, the control unit 101 determines whether or not the article placed on the mounting table 9 has been picked up based on the captured image information of the cameras CM1 to CM5 (step S105), and is said to have been picked up. When the determination is made, as described above, the height position correction control for correcting the change in the height position according to the weight change due to the picking up of the article is performed (step S106).

When it is determined in step S105 that the article placed on the mounting table 9 has not been picked up, the control unit 101 places the article on the mounting table 9 based on the captured image information of the cameras CM1 to CM5. It is determined whether or not the article has been placed (step S107), and when it is determined that the article has been placed, the process proceeds to step S106, and as described above, the change in height position according to the weight change due to the placement of the article is corrected. The height position correction control is performed (step S106).

After step S106, the control unit 101 proceeds to step S119 of FIG. 4, determines whether or not an action (gesture) or a voice end command has been received from the follower, and has not received the end command. When it is determined, the process is returned to step S105, and the processes after this step S105 are repeated.

When it is determined in step S107 that the article is not placed on the mounting table 9, the control unit 101 determines that the tracking target person is based on the captured image information of the cameras CM2 to CM5 and the sensor output of the obstacle sensor 107. It is determined whether or not it has moved (step S108). When it is determined in step S108 that the follower has moved, the control unit 101 maintains the horizontal state of the bottom surface of the mounting table 9 and moves so as to follow the movement of the follower. The unit 2 is controlled (step S109). Then, the control unit 101 advances the process to step S119 of FIG. 4, determines whether or not the action (gesture) from the follower or the end command by voice has been received, and when it is determined that the end command has not been received. , The process is returned to step S105, and the processes after this step S105 are repeated.

Further, when it is determined in step S108 that the follower is not moving, the control unit 101 determines whether or not a hovering height position change command has been received (step S111 in FIG. 4), and receives the command. When it is determined that the hovering height position is determined to be high, the hovering height position is controlled to be lowered or raised according to an instruction (step S112). After this step S112, the control unit 101 advances the process to step S119, determines whether or not an action (gesture) or a voice end command has been received from the follower, and determines that the end command has not been received. When this is done, the process is returned to step S105, and the processes after this step S105 are repeated.

When it is determined in step S111 that the hovering height position change command has not been received, the control unit 101 determines whether or not the rotation command of the mounting table 9 has been received (step S113), and determines that the command has been received. Occasionally, as described above, the bottom surface of the mounting table 9 is controlled to be rotated around the center position while maintaining the horizontal state according to the rotation command (step S114). After this step S114, the control unit 101 advances the process to step S119, determines whether or not an action (gesture) or a voice end command has been received from the follower, and determines that the end command has not been received. When this is done, the process is returned to step S105, and the processes after this step S105 are repeated.

When it is determined in step S113 that the rotation command of the mounting table 9 has not been received, the control unit 101 has the height of the lower jaw, which is an example of the physical part of the follower, which is the reference of the height position for hovering. It is determined whether or not the position is displaced upward or downward (step S115). The amount of displacement above or below determined in this case is a significant amount of displacement such that it is considered necessary to change the height position at which the levitation moving table 1 is hovering.

When it is determined in step S115 that the height position of the lower jaw, which is an example of the physical part of the follower, is displaced upward or downward, the control unit 101 is predetermined after the displacement starts. It is determined whether or not a predetermined time, for example, 5 seconds or more has elapsed (step S116), and when it is determined that the predetermined time or more has not elapsed, the current height position of the mounting table 9 is maintained (step S117). After that, the process returns to step S115.

When it is determined in step S116 that the significant upward or downward displacement of the height position of the lower jaw, which is an example of the physical part of the follower, continues for a predetermined time or longer, the control unit 101 hovering. The height position is controlled to be raised or lowered according to the displacement of the height position of the lower jaw, which is an example of the physical part of the follower (step S118).

In the processes from step S115 to step S118, when the follower crouches or stretches and the position of the lower jaw is displaced up and down, if it is a short time, the follower does not follow the original. A process of waiting in a hovering state at a height position and changing the hovering height position of the levitation moving table 1 according to the displacement of the position of the lower jaw when it waits for a predetermined time or longer. Is. This is because it is considered that a short-time change in the lower jaw of the follower does not require a change in the height position of the mounting table 9, so that unnecessary change control of the height position of the floating moving table 1 is avoided. It is a process for.

After this step S118, the control unit 101 advances the process to step S119, determines whether or not the action (gesture) or the end command by voice has been received from the follower, and determines that the end command has not been received. When this is done, the process is returned to step S105, and the processes after this step S105 are repeated.

When it is determined in step S115 that the height position of the lower jaw, which is an example of the physical part of the follower, is not displaced upward or downward, the control unit 101 advances the process to step S119 and advances the process to the follower. It is determined whether or not the end command has been received by the action (gesture) or voice from the above, and when it is determined that the end command has not been received, the process is returned to step S105, and the processes after this step S105 are repeated.

Then, when it is determined in step S119 that the end command from the follow target person has been received, the control unit 101 ends the follow control control for the follow target person and controls the levitation moving table 1 to land (step S120). ). This completes one processing operation of the levitation moving table 1.

[Example of usage mode (mode) of the floating mobile table 1 of the first embodiment]
<Cooking mode>
FIG. 5 is a diagram for explaining a state of operation performed by the floating moving table 1 in a cooking mode as an example of a usage mode (mode) of the floating moving table 1 of the first embodiment. FIG. 5 assumes a kitchen at home as a place (moving space) where the cooking mode of this example is executed.

In the example of FIG. 5, the recipe book 201 is placed on the mounting table 9 of the floating moving table 1, and various seasonings 202 such as soy sauce, salt, and pepper are placed. The recipe book 201 and the seasoning 202 are placed on the mounting table 9 of the levitation moving table 1 before the housewife 203, which is an example of the follower, is placed on the loading table 9 or is in a hovering state. It will be placed later.

Then, when the housewife 203, which is an example of the follower, gives a start command to the levitation moving table 1, the levitation moving table 1 is hovered at the above-mentioned height position while being separated from the housewife 203 by an appropriate distance. It will be in a ringing state. FIG. 5 shows the state. The housewife 203 can select herself as the follower if her face image is registered before issuing the start command, and if the cooking mode is set as the history. Can select and specify it. Further, when a suitable correspondence according to the recipe is set as a history, the recipe to be cooked may be selected and specified.

The levitation moving table 1 moves following the housewife 203, which is an example of the follow-up target person, moving between the kitchen sink 204, the cooking table 205, and the stove 206. At that time, the levitation moving table 1 moves while always maintaining the horizontal state of the bottom surface of the mounting table 9 and maintaining the height position. Then, the levitation moving table 1 avoids moving to the sky above the ignited stove 206 based on the sensor output of the temperature sensor 108. Further, the levitation moving table 1 predicts the behavior and movement of the housewife 203 by the learning unit 117 and the prediction unit 118, and hovering on the left side of the housewife 203, hovering on the right side, and the hovering position. Change as appropriate.

Further, when the housewife 203 bends down or crouches to take out an article from the drawer 207 or the cupboard 208, the levitation moving table 1 changes the hovering height position accordingly. Therefore, the housewife 203 can easily place the taken-out article on the mounting table 9 of the floating moving table 1 while bending over or crouching. The hovering height position when crouching can also be based on the position of the lower jaw of the follower, as in the case of standing. Further, the height position may be controlled according to the posture, for example, the height position may be set to a height position 10 cm lower than the position of the lower jaw instead of the height position 20 cm lower than the position of the lower jaw.

In addition, the housewife 203 gives instructions such as changing the height position of the levitation moving table 1 and changing the positions of the left side and the right side of the levitation moving table 1 according to his / her own convenience by actions (gestures) or voice commands. Can be done. Also, when the seasoning 202 is placed on the bottom surface of the mounting table 9 on the side far from the housewife 203, it is convenient to instruct the mounting table 9 to rotate so that it can be closer to oneself. Is. In this case, by recognizing the article mounted on the mounting table 9 with the captured images of the cameras CM1 to CM5, the soy sauce in the seasoning 202 is the closest when it is said to "take soy sauce". Also, if you say "toward the recipe book here", you can also instruct the recipe book 201 to rotate the mounting table 9 in the easy-to-read direction of the housewife 203. The recipe book 201 may be provided with a dedicated stand separate from the mounting stand 9 so that only the recipe book 201 can be rotated. When viewing the recipe book 201, illuminate the recipe book 201 with an LED light (not shown) provided on the upper surface of the housing 6, so that the recipe book can be firmly displayed even if it becomes dark or in the shadow. You can cook while watching.

As described above, in the cooking work, the housewife is in the cooking work by placing the recipe book 201 on the mounting table 9 of the floating moving table 1 and placing the necessary seasoning 202 in advance. Since the floating moving table 1 moves according to one's own movement, cooking work can be easily performed while looking at the recipe book 201 each time, and the seasoning placed on the mounting table 9 of the floating moving table 1 is possible. The effect is that 202 can be appropriately and appropriately selected and used on the spot. Of course, not only the recipe book 201 and the seasoning 202 but also ingredients and cooking utensils may be placed on the mounting table 9.

<Laundry drying mode and laundry loading mode>
FIG. 6 is a diagram for explaining a state of operation performed by the floating moving table 1 in the laundry drying mode as an example of the usage mode (mode) of the floating moving table 1 of the first embodiment. FIG. 6 assumes a laundry drying place at home as a place (moving space) in which the laundry drying mode of this example is executed.

Housewife 203, which is an example of the follow-up target, takes out the washed laundry from the washing machine, puts it in the laundry basket 210, and floats the laundry basket 210 containing the washed laundry. It is placed on the mounting table 9 of the moving table 1. Then, the housewife 203 gives a start command to the levitation moving table 1 by voice or action (gesture). Also in this example, the housewife 203, which is an example of the follow-up target person, is the follow-up target person when his / her face image is registered on the mounting table 9 of the levitation mobile table 1 before issuing the flight start command. You can select yourself as, and if the cooking mode is set as history, you can select and specify it.

When the start command is detected, the levitation moving table 1 is in a state of hovering at the above-mentioned height position in a state of being separated from the housewife 203, which is an example of the follower, by an appropriate distance. Then, when the housewife 203 moves to the laundry drying area, the floating moving table 1 moves to the laundry drying area following the housewife 203 with the laundry basket 210 placed on it. FIG. 6 shows the state.

At the laundry drying place, the housewife 203 takes out the laundry 211 from the laundry basket 210 placed on the loading table 9 of the floating moving table 1 and hangs it on the clothes drying rod 212 to dry it. At this time, when the control unit 101 of the levitation moving table 1 detects by the learning unit 117 that, for example, the housewife 203 always positions the laundry basket 210 on its right side, the hovering position is set to the housewife 203. Control so that it is on the right side. Then, when the housewife 203 moves according to the progress of the laundry drying work, the levitation moving table 1 also moves following the movement.

When the laundry drying operation is completed, the housewife 203 returns from the laundry drying area to a place in the room where, for example, a washing machine is located. Then, since the levitation moving table 1 follows the movement, the housewife 203 gives an end command to the levitation moving table 1. Then, the levitation mobile platform 1 lands and ends its operation. The housewife 203 lowers the laundry basket 210 from which the laundry has been emptied from the mounting table 9 of the floating moving table 1 and finishes the work.

In the laundry take-in mode, the housewife 203 takes in the laundry instead of drying the laundry, puts it in the laundry basket 210, and moves it indoors. Therefore, the levitation moving table 1 operates in the same manner as described above. Is to do.

As described above, in both the laundry drying mode and the laundry taking-in mode, the floating moving table 1 transports the laundry basket 210, assists when taking out the laundry from the laundry basket 210, and the laundry basket 210. Since it plays a role of assisting the laundry in taking in the dry laundry, the housewife 203 has an advantage that the work of drying the laundry and taking in the laundry becomes easy and is very easy to use.

<Fluorescent tube replacement mode>
FIG. 7 is a diagram for explaining a state of operation performed by the floating moving table 1 in the fluorescent tube exchange mode as an example of the usage mode (mode) of the floating moving table 1 of the first embodiment. FIG. 7 assumes a home, for example, a living room, as a place (moving space) in which the fluorescent tube exchange mode of this example is executed.

The householder 221 who is an example of the follower places a new fluorescent tube 222, a glow starter (glow starter) 223, a bean ball 224, and the like for replacement on the mounting table 9 of the floating moving table 1. Then, the family member 221 gives a start command to the levitation mobile platform 1 by voice or action (gesture). Also in this example, the householder 221 who is an example of the follow-up target person is the follow-up target person when his / her face image is registered on the mounting table 9 of the levitation mobile table 1 before issuing the flight start command. You can select yourself as, and if the fluorescent tube replacement mode is set as a history, you can select and specify it.

When the start command is detected, the levitation moving table 1 is in a state of hovering at the above-mentioned height position in a state of being separated from the householder 221 which is an example of the follow-up target person by an appropriate distance. Then, when the family member 221 climbs the stepladder 225, the levitation moving table 1 changes the height position according to the movement of the family member 221 with a delay of about 10 seconds in this example. Then, when the householder 221 reaches the height position where the fluorescent tube is replaced and stops moving above it, the floating moving table 1 also follows the householder 221 so that the height of the householder 221 is increased. Hovering is performed 20 cm below the position of the lower jaw, which is a physical part that serves as an example of the standard. FIG. 7 shows the state. At this time, when the control unit 101 of the levitation mobile table 1 detects by the learning unit 117 that, for example, the householder 221 always positions the levitation mobile station 1 on his / her left side, the hovering position is set to the householder 221. Control so that it is on the left side of. In addition, at this position, the householder 221 can adjust the hovering height position of the levitation moving table 1 and the horizontal position centered on himself by actions (gestures) or voice commands.

In this state, the householder 221 removes the old fluorescent tube 226 from the fluorescent lamp fixture (not shown), puts it on the mounting table 9 of the floating moving table 1, picks up the new fluorescent tube 222, and picks up the new fluorescent lamp fixture. Work to attach to. Subsequently, the glow starter 223 replacement work, the bean ball 224 replacement work, and the like are performed as necessary.

When the replacement work is completed, the householder 221 gets off the stepladder 225. At that time, the family member does not need to have anything. Along with the movement of the family member 221 down the stepladder 225, the levitation movement table 1 also moves down with a slight delay (10 seconds).
