Background

Surface cleaning devices must be completed with a wet cloth of immersion fluid during the cleaning of household floors. The immersion fluid is immersed below a container of cleaning fluid containing the cleaning fluid such that the immersion fluid absorbs a quantity of the cleaning fluid from the container. The dip-wetting cloth is then moved over the surface to apply the cleaning liquid to the surface. The immersion fluid wet cloth interacts with contaminants on the floor, which are attached to the immersion fluid wet cloth to achieve a cleaning objective.

Household surface cleaning devices, which have a floor mopping function, comprise a liquid storage container accommodated on a chassis for storing a supply of cleaning liquid therein, which is automatically returned to a charging post for charging when a sweeping process is completed.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

It should be understood that although the terms first, second, third, etc. may be used to describe … … in embodiments of the present disclosure, these … … should not be limited to these terms. These terms are used only to distinguish … … from each other. For example, the first … … can also be referred to as the second … … and, similarly, the second … … can also be referred to as the first … … without departing from the scope of embodiments of the present disclosure.

To describe the behavior of the robot more clearly, the following directional definitions are made:

as shown in fig. 1, which is an application scenario diagram of the present disclosure, the automatic cleaning device 100 performs cleaning work in a designated area, and when a cleaning task is completed or the electric quantity is insufficient, the automatic cleaning device 100 automatically searches for the position of the charging pile 200, and after the position of the charging pile 200 is determined, the automatic cleaning device 100 automatically moves to the position of the charging pile 200 for charging.

As shown in fig. 2, the robotic cleaning device 100 may travel over the floor surface through various combinations of movement relative to three mutually perpendicular axes defined by the body 110: a front-back axis X, a lateral axis Y, and a central vertical axis Z. The forward driving direction along the forward-rearward axis X is denoted as "forward", and the rearward driving direction along the forward-rearward axis X is denoted as "rearward". The direction of the transverse axis Y is essentially the direction extending between the right and left wheels of the robot along the axis defined by the center points of the drive wheel modules 141.

The robotic cleaning device 100 may be rotated about the Y-axis. "pitch up" when the forward portion of the automatic cleaning apparatus 100 is tilted upward and the rearward portion is tilted downward, and "pitch down" when the forward portion of the automatic cleaning apparatus 100 is tilted downward and the rearward portion is tilted upward. In addition, the robot 100 may rotate about the Z-axis. In the forward direction of the automatic cleaning apparatus 100, when the automatic cleaning apparatus 100 is tilted to the right side of the X-axis, it turns to the right, and when the automatic cleaning apparatus 100 is tilted to the left side of the X-axis, it turns to the left.

As shown in fig. 3, the automatic cleaning apparatus 100 includes a machine body 110, a sensing system 120, a control system, a driving system 140, a cleaning system 150, an energy system 160, and a human-machine interaction system 170.

The machine body 110 includes a forward portion 111, a rearward portion 112, and a chassis portion 113, and has an approximately circular shape (circular front to rear), but may have other shapes including, but not limited to, an approximately D-shape with a front to rear circle.

As shown in fig. 3, the sensing system 120 includes a position determining device 121 located above the machine body 110, a bumper 122 located at the forward portion 111 of the machine body 110, a cliff sensor 123, and an ultrasonic sensor, an infrared sensor, a magnetometer, an accelerometer, a gyroscope, a odometer, etc., and provides various position information and motion state information of the machine to the control system 130. The position determining device 121 includes, but is not limited to, a camera, a laser distance measuring device (LDS). The following describes how position determination is performed by taking a laser distance measuring device of the triangulation method as an example. The basic principle of the triangulation method is based on the geometric relation of similar triangles, and is not described herein.

The laser ranging device includes a light emitting unit and a light receiving unit. The light emitting unit may include a light source that emits light, and the light source may include a light emitting element, such as an infrared or visible Light Emitting Diode (LED) that emits infrared light or visible light. Alternatively, the light source may be a light emitting element that emits a laser beam. In the present embodiment, a Laser Diode (LD) is taken as an example of the light source. In particular, a light source using a laser beam may make the measurement more accurate than other lights due to the monochromatic, directional, and collimation characteristics of the laser beam. The Laser Diode (LD) may be a spot laser for measuring two-dimensional position information of an obstacle, or a line laser for measuring three-dimensional position information of an obstacle within a certain range.

The light receiving unit may include an image sensor on which a light spot reflected or scattered by an obstacle is formed. The image sensor may be a set of a plurality of unit pixels of a single row or a plurality of rows. These light receiving elements can convert optical signals into electrical signals. The image sensor may be a Complementary Metal Oxide Semiconductor (CMOS) sensor or a Charge Coupled Device (CCD) sensor, and is preferably a Complementary Metal Oxide Semiconductor (CMOS) sensor due to cost advantages. Also, the light receiving unit may include a light receiving lens assembly. Light reflected or scattered by the obstruction may travel through a light receiving lens assembly to form an image on the image sensor. The light receiving lens assembly may comprise a single or multiple lenses. The base may support the light emitting unit and the light receiving unit, which are disposed on the base and spaced apart from each other by a certain distance. In order to measure the obstacle situation in the 360 degree direction around the robot, the base may be rotatably disposed on the main body 110, or the base itself may be rotated without rotating the emitted light, the received light by providing a rotating element. The rotating angular speed of the rotating element can be obtained by arranging the optical coupling element and the coded disc, the optical coupling element senses tooth gaps on the coded disc, and instantaneous angular speed can be obtained by dividing the sliding time of the tooth gap distance and the tooth gap distance value. The higher the density of the tooth notches on the coded disc is, the higher the measurement accuracy and precision are correspondingly, but the structure is more precise, and the calculated amount is higher; on the contrary, the smaller the density of the tooth defects is, the lower the accuracy and precision of measurement are, but the structure can be relatively simple, the calculation amount is smaller, and the cost can be reduced.

The data processing device, e.g. DSP, connected to the light receiving unit records and transmits the obstacle distance values at all angles in the direction of 0 degrees with respect to the robot to the data processing unit in the control system 130, e.g. Application Processor (AP) comprising CPU running a particle filter based positioning algorithm to obtain the current position of the robot and to map it according to this position for navigation. The positioning algorithm preferably uses instant positioning and mapping (SLAM).

Although the laser distance measuring device based on the triangulation method can measure the distance value at an infinite distance beyond a certain distance in principle, in practice, the realization of the long-distance measurement, for example, more than 6 meters, is difficult, mainly because of the size limitation of the pixel unit on the sensor of the light receiving unit, and at the same time, the laser distance measuring device is also influenced by the photoelectric conversion speed of the sensor, the data transmission speed between the sensor and the connected DSP, and the calculation speed of the DSP. The measured value obtained by the laser ranging device under the influence of temperature can also have variation which cannot be tolerated by a system, mainly because the angle between incident light and emergent light is changed due to thermal expansion deformation of a structure between the light emitting unit and the light receiving unit, and the light emitting unit and the light receiving unit can also have the temperature drift problem. After the laser ranging device is used for a long time, the measurement result is also seriously influenced by deformation caused by accumulation of various factors such as temperature change, vibration and the like. The accuracy of the measuring result directly determines the accuracy of the map drawing, and is the basis for further strategy implementation of the robot, and is particularly important.

As shown in fig. 3, the forward portion 111 of the machine body 110 may carry a bumper 122, the bumper 122 detects one or more events in the travel path of the automatic cleaning apparatus 100 via a sensor system, such as an infrared sensor, when the driving wheel module 141 propels the robot to walk on the ground during cleaning, and the automatic cleaning apparatus 100 may control the driving wheel module 141 to cause the automatic cleaning apparatus 100 to respond to the events, such as to move away from an obstacle, by the events detected by the bumper 122, such as an obstacle, a wall.

The control system 130 is disposed on a circuit board in the machine body 110, and includes a non-transitory memory, such as a hard disk, a flash memory, and a random access memory, a communication computing processor, such as a central processing unit, and an application processor, and the application processor uses a positioning algorithm, such as SLAM, to map an instant map of the environment where the robot is located according to the obstacle information fed back by the laser ranging device. And the current working state of the sweeper is comprehensively judged by combining distance information and speed information fed back by the buffer 122, the cliff sensor 123, the ultrasonic sensor, the infrared sensor, the magnetometer, the accelerometer, the gyroscope, the odometer and other sensing devices, for example, when the sweeper passes a threshold, a carpet is arranged at the cliff, the upper part or the lower part of the sweeper is clamped, a dust box is full, the sweeper is taken up and the like, and a specific next-step action strategy is provided according to different conditions, so that the robot can work more according with the requirements of an owner, and better user experience is achieved. Further, the control system 130 can plan the most efficient and reasonable cleaning path and cleaning mode based on map information drawn by the SLAM, thereby greatly improving the cleaning efficiency of the robot.

As shown in fig. 4, the drive system 140 may steer the robot 100 across the ground based on drive commands having distance and angle information, such as x, y, and theta components. The drive system 140 includes a drive wheel module 141, and the drive wheel module 141 can control both the left and right wheels, and in order to more precisely control the motion of the machine, it is preferable that the drive wheel module 141 includes a left drive wheel module and a right drive wheel module, respectively. The left and right drive wheel modules are opposed along a transverse axis defined by the body 110. In order for the robot to be able to move more stably or with greater mobility over the ground, the robot may include one or more driven wheels 142, including but not limited to universal wheels. The driving wheel module comprises a traveling wheel, a driving motor and a control circuit for controlling the driving motor, and can also be connected with a circuit for measuring driving current and a milemeter. The driving wheel module 141 may be detachably coupled to the main body 110 to facilitate disassembly and maintenance. The drive wheel may have a biased drop-type suspension system movably secured, e.g., rotatably attached, to the robot body 110 and receiving a spring bias biased downward and away from the robot body 110. The spring bias allows the drive wheel to maintain contact and traction with the floor surface with a certain landing force while the cleaning elements of the robotic cleaning device 100 also contact the floor surface 10 with a certain pressure.

The cleaning system may be a dry cleaning system 150 and/or a wet cleaning system 153. As a dry cleaning system, the main cleaning function is derived from the sweeping system 151 constituted by the roll brush, the dust box, the blower, the air outlet, and the connecting members therebetween. The rolling brush with certain interference with the ground sweeps the garbage on the ground and winds the garbage to the front of a dust suction opening between the rolling brush and the dust box, and then the garbage is sucked into the dust box by air which is generated by the fan and passes through the dust box and has suction force. The dust removal capacity of the sweeper can be characterized by the sweeping efficiency of garbage, the sweeping efficiency is influenced by the structure and the materials of the rolling brush, the wind power utilization rate of an air duct formed by the dust suction port, the dust box, the fan, the air outlet and connecting parts among the dust suction port, the dust box, the fan, the air outlet and the dust box, and the type and the power of the fan. Compared with the common plug-in dust collector, the improvement of the dust removal capability is more significant for the cleaning robot with limited energy. Because the improvement of the dust removal capability directly and effectively reduces the energy requirement, namely the machine which can clean the ground of 80 square meters by charging once can be developed into the machine which can clean 100 square meters or more by charging once. And the service life of the battery, which reduces the number of times of charging, is also greatly increased, so that the frequency of replacing the battery by the user is also increased. More intuitively and importantly, the improvement of the dust removal capability is the most obvious and important user experience, and the user can directly draw a conclusion whether the sweeping/wiping is clean. The dry cleaning system may also include an edge brush 152 having an axis of rotation that is angled relative to the floor for moving debris into the roller brush area of the cleaning system.

The wet cleaning system 153 mainly includes a detachable water tank (not shown) disposed at the rear end of the chassis, the water tank is fixed to the bottom end of the chassis by a snap structure or a plurality of fixing screws, the bottom layer of the water tank includes a detachable mop cloth (not shown), and the mop cloth is connected to the bottom layer of the water tank by a sticking manner.

Energy source system 160 includes rechargeable batteries such as nickel metal hydride batteries and lithium batteries. The charging battery can be connected with a charging control circuit, a battery pack charging temperature detection circuit and a battery under-voltage monitoring circuit, and the charging control circuit, the battery pack charging temperature detection circuit and the battery under-voltage monitoring circuit are connected with the single chip microcomputer control circuit. The host computer is connected with the charging pile through a charging electrode (which can be arranged as a first charging contact sheet 161 and a second charging contact sheet 162) arranged on the side of the body or below the chassis for charging.

The human-computer interaction system 170 comprises keys on a panel of the host computer, and the keys are used for a user to select functions; the machine control system can further comprise a display screen and/or an indicator light and/or a loudspeaker, wherein the display screen, the indicator light and the loudspeaker show the current state or function selection item of the machine to a user; and a mobile phone client program can be further included. For the path navigation type automatic cleaning equipment, a map of the environment where the equipment is located and the position of a machine can be displayed to a user at a mobile phone client, and richer and more humanized function items can be provided for the user.

Fig. 5 is an electrical connection block diagram of an automated cleaning apparatus provided in accordance with an embodiment of the present invention.

The automatic cleaning apparatus according to the current embodiment may include: a microphone array unit for recognizing a user's voice, a communication unit for communicating with a remote control device or other devices, a moving unit for driving the main body, a cleaning unit, and a memory unit for storing information. An input unit (a key of the sweeping robot, etc.), an object detection sensor, a charging unit, a microphone array unit, a direction detection unit, a position detection unit, a communication unit, a driving unit, and a memory unit may be connected to the control unit to transmit or receive predetermined information to or from the control unit.

The microphone array unit may compare the voice input through the receiving unit with information stored in the memory unit to determine whether the input voice corresponds to a specific command. If it is determined that the input voice corresponds to a specific command, the corresponding command is transmitted to the control unit. If the detected speech cannot be compared to the information stored in the memory unit, the detected speech may be treated as noise to ignore the detected speech.

For example, the detected voice corresponds to the word "come, go", and there is a word control command (come) corresponding to the word stored in the information of the memory unit. In this case, a corresponding command may be transmitted to the control unit.

The direction detecting unit may detect the direction of the voice by using a time difference or a level of the voice input to the plurality of receiving units. The direction detection unit transmits the detected direction of the voice to the control unit. The control unit may determine the moving path by using the voice direction detected by the direction detecting unit.

The position detection unit may detect coordinates of the subject within predetermined map information. In one embodiment, the information detected by the camera and the map information stored in the memory unit may be compared with each other to detect the current position of the subject. The position detection unit may use a Global Positioning System (GPS) in addition to the camera.

In a broad sense, the position detection unit may detect whether the main body is disposed at a specific position. For example, the position detection unit may include a unit for detecting whether the main body is disposed on the charging pile.

For example, in the method for detecting whether the main body is disposed on the charging pile, whether the main body is disposed at the charging position may be detected according to whether power is input into the charging unit. For another example, whether the main body is disposed at the charging position may be detected by a charging position detecting unit disposed on the main body or the charging pile.

The communication unit may transmit/receive predetermined information to/from a remote control device or other devices. The communication unit may update map information of the sweeping robot.

The driving unit may operate the moving unit and the cleaning unit. The driving unit may move the moving unit along the moving path determined by the control unit.

The memory unit stores therein predetermined information related to the operation of the sweeping robot. For example, map information of an area where the sweeping robot is arranged, control command information corresponding to a voice recognized by the microphone array unit, direction angle information detected by the direction detection unit, position information detected by the position detection unit, and obstacle information detected by the object detection sensor may be stored in the memory unit.

The control unit may receive information detected by the receiving unit, the camera, and the object detection sensor. The control unit may recognize a user's voice based on the transmitted information, detect a direction in which the voice occurs, and detect a position of the automatic cleaning apparatus. Further, the control unit may also operate the moving unit and the cleaning unit.

According to a specific embodiment of the present disclosure, an embodiment of the present disclosure provides a cleaning robot, including: a chassis; a fluid applicator carried on the chassis in electrical communication with the control system, the fluid applicator including a pump through which cleaning fluid is dispensed over at least a portion of the cleaning width, such as through a location in contact with a central location (with the outlet) of the mop swab; the robot also comprises a water tank which is detachably connected with the chassis; wherein a water tank is in communication with the fluid applicator, arranged to apply cleaning fluid dispensed by the fluid applicator to a floor surface; the cleaning robot further comprises a control system carried on the chassis, the control system being configured to control the fluid applicator to stop dispensing cleaning fluid when the area to be swept on the floor reaches a preset value.

Optionally, the fluid applicator comprises a plurality of selectable gears, each gear corresponding to a different duration and/or volume of water output; the preset value is associated with a selected gear in the fluid applicator. As shown in the following table:

as shown in the table, the bigger the gear is, the shorter the endurance time is, the faster the water outlet speed is, the more the water outlet amount is, and thus the faster the mop is wet. The controller can monitor the current gear and judge the relation between the residual area and the water yield in real time so as to ensure that the rag is just in a dry state after recharging. For one embodiment, for example, 1 gram of water is required to clean a 1 square meter floor. On average, the rag can be used for drying about 3-6 square meters after water is cut off. For the wood floor, if the residual area is less than 4 square meters, the water outlet needs to be forcibly closed, at the moment, the cleaning robot returns to the charging seat when the residual area is cleaned, and the rag at the bottom is just in a semi-dry state. Therefore, the preset value can be set according to the actual ground cleaning state, and the setting process can be obtained through a plurality of experimental structures, for example, the water supply is stopped when the residual area is set to be 4 square meters. The cleaning robot uses the wet mop to work, after the cleaning of the rest 4 square meters of ground is finished, the charging threshold value is just reached, the control system controls the cleaning robot to return to the charging pile for charging, and the mop is in a non-wet state at the moment.

Optionally, the cleaning robot further comprises: and the navigation device calculates the cleaned area by monitoring the running track of the cleaning robot in real time and reports the cleaned area to the control system, and the control system calculates and obtains the area to be cleaned according to the cleaned area. The area to be cleaned is equal to the difference between the total area and the cleaned area, wherein the total area is calculated as one of the following:

1) for a global sweep mode, the total area is equal to the maximum area for autonomous sweep completion in historical global sweeps;

2) for the selected area sweeping mode, the total area is equal to the sum of the sizes of all selected areas;

3) for the zone sweep mode, the total area is equal to the sum of all zone sizes.

A designated cleaning mode can be selected through a mobile phone APP or a cleaning robot setting interface, and the cleaning mode comprises a global cleaning mode, a selective cleaning mode or a zoning cleaning mode. Here, the global cleaning mode is that all areas in a map drawn by a navigation device of the cleaning robot, for example, all areas drawn by the map are divided into four sub-areas, namely, an area one (bedroom 1), an area two (bedroom 2), an area three (kitchen) and an area four (living room), as shown in fig. 6, at this time, if the global cleaning mode is selected, the area that the cleaning robot is responsible for cleaning includes four areas of the whole room, and the cleaning area is the sum of the areas of the four areas. The selective cleaning mode is a mode in which the user can select one or more of the first area (bedroom 1), the second area (bedroom 2), the third area (kitchen), and the fourth area (living room) to perform cleaning, for example, when the user selects the first area to perform cleaning, the cleaning robot performs cleaning within the first area, and the cleaning area is the area of the first area. The division cleaning mode is that a user can define a range in any one or more of the first area (bedroom 1), the second area (bedroom 2), the third area (kitchen) and the fourth area (living room) to clean (for example, the dotted line area in fig. 6), and the cleaning robot then cleans only in the corresponding dotted line area, and the cleaning area is the sum of the areas of the two dotted line areas in fig. 6.

Wherein, any kind of total area all can be through the navigation head through cleaning many times, to cleaning the regional scanning back calculation obtain the whole regional area sum, should clean area or map storage in cleaning robot storage equipment to can show the terminal through user APP, the user can set up cleaning process at the APP interface.

Optionally, the cleaning robot further comprises: an energy storage unit supported by the chassis and configured to just reach a charging threshold when the area to be swept is cleaned. In particular, the energy storage unit comprises at least one charging contact 161 for automatic charging after contact with the poles of the charging post when the robot is positioned at a charging station.

One embodiment can be described as the control system obtains the remaining capacity of the energy storage unit when the area to be cleaned is cleaned, and when the remaining capacity is within the chargeable range (for example, 15% -25%), the control system controls the driving system of the cleaning device to search for the position of the charging pile, and when the position of the charging pile is obtained, the control system moves to the charging interface of the charging pile to perform automatic charging.

Another embodiment may be described in which when the area to be cleaned is close to the cleaning completion range (for example, more than 90% of the cleaning completion remaining area), the control system obtains the remaining power of the energy storage unit, and when the remaining power reaches a threshold value (for example, 15%) to be charged, the control system controls the driving system of the cleaning device to search for the position of the charging pile, and when the position of the charging pile is obtained, the control system travels to the charging interface of the charging pile to perform automatic charging. And if the residual area of the area to be cleaned does not reach the charging threshold, charging after the cleaning of the residual area of the area to be cleaned is finished.

Optionally, the method further includes: and the liquid level detector is arranged in the fluid storage device and used for detecting the liquid level of the fluid storage device in real time when the robot performs a task, and sending an alarm signal to the control unit when the liquid level is lower than an early warning value.

According to a specific embodiment of the present disclosure, an embodiment of the present disclosure provides a fluid control method for a cleaning robot, where for portions of the cleaning robot that have the same structure, see the above description, the same portions have the same technical effects, and are not described herein again, where the method includes the following method steps, as shown in fig. 7:

step S702: monitoring the cleaned area in real time through a navigation device, reporting the cleaned area to a control unit, and calculating by the control unit according to the cleaned area to obtain the area to be cleaned;

step S704: when the area to be cleaned reaches a preset value, the control unit controls the fluid applicator to stop dispensing the cleaning fluid.

Optionally, the fluid applicator comprises a plurality of selectable gears (e.g. third gear), each gear corresponding to a different duration and/or volume of water output; the preset value is associated with a selected gear in the fluid applicator.

Optionally, the preset value is configured to enable the energy storage unit to just reach a charging threshold when the cleaning of the area to be cleaned is completed. When the energy storage unit reaches a charging threshold value, the robot moves to a charging station and is charged through a charging contact piece in the energy storage unit.

Optionally, when the robot performs a task, the liquid level of the fluid storage device is monitored in real time, and when the liquid level is lower than an early warning value, an alarm signal is sent to the control unit; the control unit changes the advancing characteristic of the robot and simultaneously sends liquid volume shortage prompt information to a user. And after receiving a cleaning continuing instruction of the user, the robot continues the previous task.

Optionally, the preset value is related to a ground material. For example, for tile floors, the preset value of the residual area can be larger, for example, 6 square meters, and the wood floor is relatively water-consuming, and the preset value of the residual area can be smaller, for example, 4 square meters.

On the other hand, the preset value can be manually modified according to the actual situation, for example, after setting to 4 square meters, the mop will still be wet after the cleaning robot has returned to the charging post position, and the preset value can be set to a larger value, for example, 6 square meters.

Optionally, the obtaining of the area to be cleaned by calculating according to the cleaned area includes: the area to be cleaned is equal to the difference between the total area and the cleaned area, wherein the total area is calculated as one of the following:

for a global sweep mode, the total area is equal to the maximum area for autonomous sweep completion in historical global sweeps;

for the selected area sweeping mode, the total area is equal to the sum of the sizes of all selected areas;

for the zone sweep mode, the total area is equal to the sum of all zone sizes.

The description of the three modes, as mentioned above, is omitted here for brevity.

The disclosed embodiments provide a cleaning robot, comprising a processor and a memory, wherein the memory stores computer program instructions capable of being executed by the processor, and the processor executes the computer program instructions to implement the method steps of any of the foregoing embodiments.

The disclosed embodiments provide a non-transitory computer readable storage medium storing computer program instructions which, when invoked and executed by a processor, implement the method steps of any of the preceding embodiments.

As shown in fig. 8, the robot may include a processing device (e.g., central processing unit, graphics processor, etc.) 801 that may perform various appropriate actions and processes according to a program stored in a Read Only Memory (ROM)802 or a program loaded from a storage device 808 into a Random Access Memory (RAM) 803. The RAM 803 also stores various programs and data necessary for the operation of the electronic robot. The processing apparatus 801, the ROM 802, and the RAM 803 are connected to each other by a bus 804. An input/output (I/O) interface 805 is also connected to bus 804.

Generally, the following devices may be connected to the I/O interface 805: input devices 806 including, for example, a touch screen, touch pad, keyboard, mouse, camera, microphone, accelerometer, gyroscope, etc.; output devices 807 including, for example, a Liquid Crystal Display (LCD), speakers, vibrators, and the like; storage 808 including, for example, magnetic tape, hard disk, etc.; and a communication device 809. The communication means 809 may allow the electronic robot to perform wireless or wired communication with other robots to exchange data. While fig. 8 illustrates an electronic robot having various means, it is to be understood that not all of the illustrated means are required to be implemented or provided. More or fewer devices may alternatively be implemented or provided.

In particular, according to an embodiment of the present disclosure, the processes described above with reference to the flowcharts may be implemented as computer software programs. For example, embodiments of the present disclosure include a computer program product comprising a computer program embodied on a computer readable medium, the computer program comprising program code for performing the method illustrated in the flow chart. In such an embodiment, the computer program may be downloaded and installed from a network through the communication means 809, or installed from the storage means 808, or installed from the ROM 802. The computer program, when executed by the processing apparatus 801, performs the above-described functions defined in the methods of the embodiments of the present disclosure.

It should be noted that the computer readable medium in the present disclosure can be a computer readable signal medium or a computer readable storage medium or any combination of the two. A computer readable storage medium may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any combination of the foregoing. More specific examples of the computer readable storage medium may include, but are not limited to: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the present disclosure, a computer readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device. In contrast, in the present disclosure, a computer readable signal medium may comprise a propagated data signal with computer readable program code embodied therein, either in baseband or as part of a carrier wave. Such a propagated data signal may take many forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer readable signal medium may also be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to: electrical wires, optical cables, RF (radio frequency), etc., or any suitable combination of the foregoing.

The computer readable medium may be embodied in the robot; or may be separate and not assembled into the robot.

Computer program code for carrying out operations for aspects of the present disclosure may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C + +, and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the case of a remote computer, the remote computer may be connected to the user's computer through any type of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet service provider).
