Referring back to FIG. 1, the user terminal 20 is used by a user of the mobile sales system 1 and is an example of a terminal device. The user terminal 20 is implemented as a portable terminal device such as a smartphone or a tablet terminal. The user terminal 20 outputs a call request to the server device 30 for requesting a mobile sales robot 10 to come to a user position. The number of the user terminals 20 is not limited.


The server device 30 manages the mobile sales system 1. The server device 30 is implemented as, for example, an information processing device such as a personal computer (PC). The server device 30 tracks the commodities (items) sold by each mobile sales robot 10. The server device 30 manages the mobile sales robot 10 and causes the mobile sales robot 10 to travel toward a call position designated by a call request received from a user terminal 20. For example, the server device 30 tracks current positions of the mobile sales robots 10 and the user terminals 20, and causes a mobile sales robot 10 designated by the call request to travel toward the position of the user terminal 20 after receiving a call request for the mobile sales robot 10 from the user terminal 20.


A hardware configuration and functional aspects of components provided in the mobile sales system 1 will be described.



FIG. 6 is a diagram illustrating an example of the hardware configuration of the mobile sales robot 10. As illustrated in FIG. 6, the mobile sales robot 10 includes a central processing unit (CPU) 151, a read only memory (ROM) 152, a random access memory (RAM) 153, and a storage unit 162.


The CPU 151 is an example of a processor, and integrally controls each unit of the mobile sales robot 10. The ROM 152 stores various programs. The RAM 153 provides a workspace for loading the programs and various types of data.


The storage unit 162 can be a storage medium such as a hard disk drive (HDD) or a flash memory, and maintains a stored content even when the power supply is cut off. The storage unit 162 stores programs and various types of setting information that can be executed by the CPU 151.


The CPU 151, the ROM 152, and the RAM 153 are connected via a bus or the like, and constitute the control unit 154. In the control unit 154, the CPU 151 operates in accordance with a program stored in the ROM 152 or the storage unit 162 and loaded in the RAM 153, thereby executing various processes.


The mobile sales robot 10 further includes the light emitting unit 114, the driving unit 123, and the imaging unit 134. The mobile sales robot 10 further includes a display unit 155, an operation unit 156, a sound collection unit 157, a sensor unit 158, weight detection units 159, a positioning unit 160, a communication unit 161, and the like.


The display unit 155 is a display device such as the first display unit 131, the second display unit 132, the third display unit 133, the fourth display unit 135, and/or the shelf labels 113. The display unit 155 is implemented by a liquid crystal display (LCD) or the like. The display unit 155 displays various types of information under control of the CPU 151.


The operation unit 156 is input device and outputs user inputs received from the user to the CPU 151. The operation unit 156 can be a touch panel superposed on a display screen of the display unit 155 other than the shelf labels 113. In the present example, the first display unit 131, the second display unit 132, the third display unit 133, and the fourth display unit 135 provided with a touch panel serving as an operation unit 156.


The sound collection unit 157 collects sound around the mobile sales robot 10, and outputs a sound signal of the collected sound to the CPU 151. The sound collection unit 157 can be a device such as a microphone. The sound collection unit 157 collects, for example, a voice command/request for causing the mobile sales robot 10 to stop traveling from a user who wants to purchase a commodity during the patrol traveling from the mobile sales robot 10.


The sensor unit 158 is a sensor device such as the distance measuring sensor 115. The sensor unit 158 outputs a detection result obtained by sensing to the CPU 151.


The weight detection unit 159 is a weight sensor that detects a weight of the commodities accommodated in the accommodating unit 111. Specifically, the weight detection unit 159 is provided on each shelf 112, and detects the weight and the weight change of the commodities placed on the shelf 112.


In this example, a weight detection unit 159 is provided corresponding for each shelf 112, and when a weight change is detected by a weight detection unit 159, the shelf 112 having the change can be identified.


When the shelf 112 is divided into a plurality of regions, a weight detection unit 159 may be provided for each divided region. In this case, the divided regions and the weight detecting units 159 provided for the regions are correlated.


The positioning unit 160 measures a current position of the mobile sales robot 10. The positioning unit 160 can be implemented by, for example, a positioning device using a positioning technique such as a global positioning system (GPS).


The positioning unit 160 may be implemented by a position measuring device using a positioning technique such as beacon positioning and radio frequency identifier (RFID) positioning. In this case, by providing a terminal corresponding to the positioning technique such as the beacon positioning and the RFID positioning at several positions within a travelling range of mobile sales robot 10, the current position of the mobile sales robot 10 can be measured (specified) by a positioning system including the terminals and the positioning unit 160.


The communication unit 161 is a wireless communication interface connectable to the network N. The communication unit 161 communicates with an external device such as the server device 30 via the network N.


The storage unit 162 stores map information 1621, a commodity master 1622, and an accommodated commodity table 1623. Here, the map information 1621 is information indicating a map of the range in which the mobile sales robot 10 moves.


The commodity master 1622 is a data table for storing information related to the commodity to be sold. The commodity master 1622 stores, in association with a commodity code for identifying a commodity, commodity information of the commodity corresponding to the commodity code. The commodity information includes the commodity name, a type, the price, the weight, image data, and the like. The commodity master 1622 may store image data representing a feature of the commodity in the commodity information.


In some examples, the storage unit 162 may not store the commodity master 1622. In this case, the mobile sales robot 10 can handle a commodity master similarly to a configuration of storing the commodity master 1622 by referring to a commodity master stored in the server device 30.


The accommodated commodity table 1623 is a data table for storing information related to items (merchandise) accommodated in the accommodating unit 111. The accommodated commodity table 1623 stores, in association with a shelf ID capable of identifying the shelf 112 provided in the accommodating unit 111, the commodity codes and the number of the commodities placed on the shelf 112 of the corresponding shelf ID. When the shelf 112 is divided into a plurality of regions, the accommodated commodity table 1623 may allocate an identifier for each divided region, and store the commodity codes and the number of the commodities placed in each of the regions.



FIG. 7 is a block diagram illustrating an example of the functional aspects of the mobile sales robot 10.


The control unit 154 of the mobile sales robot 10 functions as a transmission and reception unit 1541, an input reception unit 1542, a self-position specifying unit 1543, an information processing unit 1544, a drive control unit 1545, and a display control unit 1546 (display controller) by the CPU 151 operating in accordance with a control program stored in the ROM 152 or the storage unit 162. In some examples, the described functions may be implemented by hardware such as a dedicated circuit.


The transmission and reception unit 1541 transmits and receives various types of information to and from an external device such as the server device 30 via the communication unit 161. For example, the transmission and reception unit 1541 transmits position information illustrating a position of the mobile sales robot 10 and state information illustrating a state of the mobile sales robot 10 to the server device 30 at any time.


The transmission and reception unit 1541 transmits an authentication request to the server device 30 and receives an authentication notification from the server device 30. The authentication request is for requesting authentication by a pin code input to the input reception unit 1542, and includes the pin code and a robot ID received by the input reception unit 1542. The transmission and reception unit 1541 transmits a settlement request to the server device 30 and receives a settlement completion notification from the server device 30. The settlement process is executed by the server device 30 in this example.


The input reception unit 1542 receives input information based on an operation of the operation unit 156 by a user. For example, the input reception unit 1542 receives a pin code and a settlement instruction input by an operation of the user.


The self-position specifying unit 1543 specifies the position of the mobile sales robot 10 in the map information 1621 based on an output of the positioning unit 160.


The information processing unit 1544 executes various processes based on various types of information input into the mobile sales robot 10.


For example, when the transmission and reception unit 1541 receives a movement instruction from the server device 30, the information processing unit 1544 determines a movement route to the call position based on the map information 1621.


When the weight detection unit 159 detects the weight change of a shelf 112, the information processing unit 1544 reads the commodity code(s) corresponding to the shelf ID of the shelf 112 having the weight change from the accommodated commodity table 1623, and identifies the commodity removed from the shelf 112 (or the commodity returned to the shelf 112).


For example, when the weight change is a decrease in weight, the information processing unit 1544 reads the commodity codes stored in association with the shelf ID of the shelf 112 having the weight change. Then, the information processing unit 1544 refers to the commodity master 1622 to specify a commodity code corresponding to the decreased weight among weights associated with the read commodity codes, thereby identifying a particular commodity taken from the shelf 112. In this case, the information processing unit 1544 reads commodity information corresponding to the specified commodity codes from the commodity master 1622 and registers the commodity information in the RAM 153 (hereinafter, also referred to as “commodity registration”). That is, the information processing unit 1544 also functions as a registration unit that executes a commodity registration operation. The information processing unit 1544 subtracts the number of items taken out from the shelf 112 from the number of the specified commodity codes stored in the accommodated commodity table 1623.


If the weight change is an increase in weight, the information processing unit 1544 reads the commodity codes stored in association with the shelf ID of the shelf 112 having the weight change. Then, the information processing unit 1544 refers to the commodity master 1622 to identify a commodity code corresponding to the increased weight among weights associated with the read commodity codes, thereby specifying which commodity has been returned to the shelf 112. In this case, the information processing unit 1544 deletes the commodity information corresponding to the specified commodity code from the RAM 153 (e.g., from the registered commodity list). The information processing unit 1544 increases the number of the commodities presently stored the shelf 112 in the accommodated commodity table 1623 to reflect the return of the item to the shelf 112.


In some examples, the registration of the commodity information may be executed by the server device 30. Specifically, the information processing unit 1544 transmits the commodity code of the commodity taken from the shelf 112 to the server device 30 via the transmission and reception unit 1541. Then, the server device 30 reads, from the commodity master stored in the server device 30, the commodity information corresponding to the received commodity code, and registers the commodity information. In this case, the information processing unit 1544 implements a function of causing the server device 30 to register the commodity information.


When the input reception unit 1542 receives the settlement instruction (request to complete the sales transaction), the information processing unit 1544 executes a payment process. The payment process is a process by which the user pays a purchase price of any removed items. In the present embodiment, the payment process includes calculation of the total purchase price for items for which the commodity registration was executed, acquisition of face image data of the purchasing customer, and transmission of the settlement request to the server device 30.


The server device 30 executes the settlement process when the settlement request is received from the mobile sales robot 10. In the present embodiment, the server device 30 executes an electronic settlement process based on face authentication. Specifically, the server device 30 executes settlement using settlement information associated with the user corresponding to the face image data. In the present example, the server device 30 executes the settlement process by communicating with a settlement server of a settlement processor companying (e.g., a credit card company or electronic payment service). The server device 30 may also or instead perform electronic settlement by credit card settlement or two-dimensional code settlement.


When the mobile sales robot 10 executes the settlement process rather than the server device 30, the payment process executed by the information processing unit 1544 includes the operations associated with settlement process described above. In some examples, the mobile sales robot 10 may include an automatic change machine or the like for handling cash settlement. In this case, the information processing unit 1544 controls the automatic change machine as appropriate.


The information processing unit 1544 executes sound recognition on the sound collected by the sound collection unit 157, and outputs a stop instruction to the drive control unit 1545 as necessary. For example, the information processing unit 1544 outputs a stop instruction to the drive control unit 1545 when a sound (voice command/request) for causing the mobile sales robot 10 to stop is recognized by sound recognition.


When the transmission and reception unit 1541 receives an authentication notification from the server device 30, the information processing unit 1544 permits processes related to the sale of merchandise and the like. That is, when the user who calls the mobile sales robot 10 and a user who intends to start shopping are matched with each other by the server device 30, the information processing unit 1544 permits the processes related to the sale of merchandise.


For example, the information processing unit 1544 cooperates with the display control unit 1546 to cause the display unit 155 to display an initial screen for starting the shopping. When the door portion for accessing the accommodating unit 111 is lockable, the information processing unit 1544 releases lock of the door portion, thereby permitting the customer to access the stored items of the mobile sales robot 10.


The drive control unit 1545 controls the driving unit 123 to cause the mobile sales robot 10 to travel or stop. The mobile sales robot 10 performs, under the control of the drive control unit 1545, patrol traveling of traveling along the predetermined route and call traveling toward the call position as designated by the customer.


The drive control unit 1545 causes the mobile sales robot 10 to move to service or restocking yard or the like when it is detected that commodities stored in the accommodating unit 111 are out of stock. When the mobile sales robot 10 travels in the shopping mall or the like, the drive control unit 1545 may cause the mobile sales robot 10 to move to a store that supplies a commodity that is presently out of stock on the mobile sales robot 10.


The display control unit 1546 controls the first display unit 131, the second display unit 132, the third display unit 133, the fourth display unit 135, and the shelf labels 113, and causes these displays (also referred to as display unit 155) to display various types of information. The display control unit 1546 changes displayed content depending on whether the mobile sales robot 10 is moving or stopped (that is, while providing customer service).


For example, if the mobile sales robot 10 is stopped, the display control unit 1546 causes the shelf label 113 (1131 and 1132) to display the commodity information including the price of the items displayed on the shelves 112. While the mobile sales robot 10 is stopped, the display control unit 1546 causes the first display unit 131 to display information related to the commodity taken out from the accommodating unit 111, and causes the third display unit 133 to display information related to the settlement of the commodity, such as information for guiding a settlement method of the commodity.


At this time, while the mobile sales robot 10 is stopped, the display control unit 1546 causes the second display unit 132 and the fourth display unit 135 to display, for example, information related to sales promotion (an advertisement) for a commodity, such as information for advertising a particular commodity accommodated in the accommodating unit 111.


If the mobile sales robot 10 is moving, the display control unit 1546 causes at least one of the first display unit 131, the second display unit 132, the third display unit 133, the fourth display unit 135, and the shelf labels 113 to display an advertisement.


A display unit such as the first display unit 131 used for the commodity registration or operation and the shelf labels 113 illustrating the commodity information during a stop for customer service and merchandise sales can be diverted to display an advertisement during movement. Therefore, a mobile sales device can be provided that can more effectively use various equipped devices during movement when a merchandise sale cannot be performed.


Described example embodiments may be modified in various aspects with respect to configuration and/or functions. In the following, certain modifications will be described.


Modification

The mobile sales robot 10 according to one modification may further include or provide a decoration acquisition unit. That is, the control unit 154 may further function as a decoration acquisition unit. The decoration acquisition unit acquires image information as decorating information to be displayed under control of the display control unit 1546. The decorating information may be stored in (and acquired from) the storage unit 162 of the mobile sales robot 10 or the server device 30.


The relevant image information may be stored in association with, for example, a particular sales area, display date, time period, and day of the week or combinations thereof corresponding to time and/or place for display of the image information (decorating information). The decoration acquisition unit may acquire image information appropriate to a particular sales area, date, time, or the like by reference to such information as present position, date, time, or the like.
