In order to describe the method of controlling the movement of the robot, one zone is designated as A and sub-zones of zone A are designated as A1 to A4, as shown in FIG. 1 for illustrative purposes only. The number of cameras 200, robot 100, beacon 16, and segmented areas shown in FIG. It is not limited to arrangement|positioning etc. In one embodiment, the camera 200 and the robot 100 may be controlled in units of zones.

At least one camera 200 and at least one robot 100 are arranged in zone A. The camera 200 and the robot 100 in the zone A can directly transmit/receive data (information) to each other without going through the server 300 . The camera 200 and the robot 100 of sub-areas A1 to A4 may share the map of area A with each other and also share the location of the robot 100 .

6 is a block diagram for controlling movement of a robot according to an embodiment. The robot 100 and the camera 200 acquire information of the sub-zones A1 to A4 (S610). The cameras 200 of sub-areas A1 to A4 collect image information of the corresponding sub-area. The robot 100 collects information on the arranged area through a sensor and a camera. The cameras 200 and the robot 100 in the sub-zones A1 to A4 communicate with each other to share information (density, residence time, gender, age, etc.) about the people in the zone A ( S620 ).

At least one of the camera 200 and the robot 100 in the zone A determines a target based on the shared information (S630). The information collected in S620 may be transmitted to the server 300, and the server 300 may determine a target based on the information collected in S620. The target may be a person, or it may be a sub-area (one of A1 to A4) densely populated with people.

In an embodiment, it is possible to determine a sub-region having the highest density of people in sub-regions A1 to A4. The density of people may be the density of the target, for example, a place where a certain gender gathers the most, a place where a certain age gathers the most, or it may be a place where people gather the most regardless of gender or age.

In an embodiment, the same goal as the goal of the pre-stored advertisement may be determined. For example, when a target of sending advertisements is a woman, an area having a high density of women may be determined as a target. If the target of sending the advertisement is a male or a child, it may be determined that the target is a male or a child. You can also change goals within the same area.

S610 to S630 may be updated at predetermined time intervals. It may be updated in units of 1 minute, 5 minutes, 10 minutes, or according to at least one advertisement time. For example, if the length of the advertisement is 30 seconds, it may be updated in 30 seconds×N time or may be updated after a plurality of advertisements are terminated. In addition, a next target may be preset while transmitting one advertisement, and the robot 100 may be moved toward the next target immediately after the advertisement is finished.

At least one of the camera 200 , the server 300 , and the robot 100 controls the movement of the robot 100 according to a target ( S640 ).

The movement of the robot 100 is controlled in consideration of various scenarios and conditions. For example, depending on the distance between the robots 100, the number of robots 100 disposed in one sub-zone, the time the robot 100 reaches the position with the highest human density, and the number of units depending on the density of people. Whether to place the robot 100, whether to preferentially place the robot 100 located in the sub-region with the highest density of people, or to request the movement of the robot 100 located in other areas (B to C), the person Whether to request movement of the robot 100 located in a sub-zone other than the sub-zone having the highest density of , whether there is a person watching the robot 100, whether the robot 100 is being advertised to the target, etc. may be considered.

In an embodiment, when a sub-zone (target zone) is determined as the target, it may be determined which robot 100 among the plurality of robots 100 will move to the target zone.

In one embodiment, the robot 100 capable of moving the fastest may be determined. The robot may be controlled to be able to move after the advertisement currently being broadcast is finished. Since each robot 100 is in the middle of transmitting an advertisement, considering the remaining time until the advertisement ends and the time the robot 100 moves from the current location of the robot 100 to the target area, the robot 100 that can reach the target area the fastest ) can control the robot 100 to move to the target area. For example, in response to receiving a signal indicating that the target area has been determined, the robot 100 transmits the remaining time and current location until the end of the currently transmitted advertisement to the server 300, and the server 300 receives the received signal. Based on the information, it is possible to calculate the movement time to the target area of each robot 100 and transmit a movement command only to the robot 100 that can reach the target area the fastest. That is, the server 300 may calculate the movement time for the robot 100 to reach the target area by using the sum of the time until the advertisement ends and the movement time of the robot 100 . The subject for calculating the time for each robot 100 to reach the target area may be the robot 100 or the camera 200 of the area in which the robot 100 is located. That is, each robot 100 calculates the time to reach the target area and transmits the arrival time to the server 300, and the server 300 transmits a movement command only to the robot 100 with the shortest arrival time. have. Each camera 200 receives the remaining time and current location from the robot 100 until the end of the advertisement currently being transmitted, calculates the arrival time to the target area, and transmits it to the server 300 , and the server 300 receives the most arrival time among them. Only this short robot 100 can transmit a movement command.

In one embodiment, since each robot 100 is in the middle of transmitting an advertisement, the robot 100 is selected in consideration of the time remaining until the advertisement ends and the time the robot moves from the place where the robot 100 is currently located to the target area. can be controlled For example, in response to receiving a signal that the target area has been determined, only the robot 100 whose time remaining until the end of the advertisement is less than or equal to the predetermined time transmits the time remaining until the end of the advertisement currently being broadcast and the current location to the server 300 can send The remaining time until the advertisement ends can be set in the server 300 .

In one embodiment, when a sub-zone (target zone) is determined as a target, the server 300 moves any one robot 100 among the robots 100 disposed in the robot unit zone including the target zone to the target zone. can be controlled to do so.

In one embodiment, when the target area is determined by comparing the calculation result with the current operation scenario, the server 300 determines the distance from the current location of each robot 100 to the target area and the number of people in the area where the robot 100 is currently located. Based on the selection, the robot 100 to move to the target area may be selected. For example, different values may be assigned according to the distance from the current position of each robot 100 to the target area. A larger value may be assigned as the distance from the current position of the robot 100 to the target area increases. Referring back to FIG. 1 , when the target area is B4, a value of 1 may be assigned to the robot 100 located in areas B2 and B3 immediately adjacent to B4. A value of 3 is assigned to the robot 100 located in areas D1, A2, and A3 2 spaces away from B4, a value of 5 is given to the robot 100 located in the C1 area 4 spaces away from B4, and a robot in a more distant area (city not) can be assigned a value of 7, 9, etc. In addition, different values may be assigned according to the number of people in the area where each robot 100 is located. Depending on the number of people in the area, the larger the number of people, the higher the value may be given. For example, different values may be assigned according to the order of the fewest number of people or the range of the number of people. That is, values such as 1, 3, 5, 7 are assigned in the order of the number of people, or the number of people is divided into ranges 0-5, 6-10, 11-15, 16-20, etc. and 1, 3, 5, 7 is assigned to each range. and the like may be assigned. These values and personnel ranges are exemplary and may be changed.

Table 1 below exemplifies the values assigned based on these moving distances and the number of people in the current area.

Item robot 1 robot 2 robot 3 robot 4 robot 5 target area travel distance One 5 One 3 9 Current Area Personnel 3 One 5 3 2 synthesis 4 6 6 6 11

The server 300 determines the motive for setting the target area for this movement (increasing the density of people, increasing the number of people in a specific class, etc.) and the result of the movement (dense maintenance time, the time to perform the target action after the robot reaches the target area, the movement time) etc.) are stored and learned, and then used as basic data for setting target areas, selecting robots to move, and calculating effects. In the above-described embodiment, a sub-zone is taken as an example, but it is obvious that the zones A, B, C, and D may be determined as the target zone. In addition, a plurality of robots 100 may be disposed in each zone, and the method shown in FIG. 6 may be applied to each zone to control the robots 100 disposed in each zone, respectively.

In one embodiment, when a movement command of the robot 100 is generated, the server 300 generates a command through a movement time to a corresponding point for the closest robot in the corresponding area, and prediction analysis of changes in the number of people staying in the area within the movement time decide whether

For example, when the robot 100 moves, the advertisement playback scenario is as follows, and the server can determine it and transmit it to the robot 100 . Proceed with the existing scenario - If the server analyzes the movement path and determines that there is no problem in the existing advertisement playback scenario, it proceeds to the existing scenario. Scenario Reorganization - The server 300 determines the advertisement reorganization in consideration of factors such as maximum effect advertisement for each area on the moving path, store arrangement, and the number of people staying, and transmits a control signal to the robot 100 . The reorganization of the advertisement may be organized so that the target advertisement is reproduced when the robot 100 reaches the corresponding area.

The robot 100 may transmit an advertisement while driving based on a previously input driving scenario. 'Driving' may be used as a generic term for general control of the robot 100, such as movement of the robot 100 and sending of advertisements. Advertising will be described later. The driving scenario may be prepared in consideration of population analysis and store layout in the area. The driving scenario may be continuously improved and modified in the server 300 by reflecting information accumulated while the robot 100 moves. The robot 100 proceeds to travel in a specific area according to the driving scenario, but detailed driving in each basic unit area may be determined based on information detected by the camera 160 of the robot 100 . In addition, a control signal may be received from the camera 200 or the server 300 installed in the corresponding area and reflected in driving and advertisement transmission. The driving sequence for the entire driving area is driven based on the previously input driving scenario. The camera 200 for each zone detects the floating population in the zone, the robot 100's entry into a specific zone (FIGS. 5A to 5D), etc., and sends information to be reflected in the driving of the robot 100 to the server or the robot ( 100) to send a control signal.

In one embodiment, the information may be in the form of step-by-step (eg, level 1, level 2, level 3... information) reflecting calculation factors such as the total number of people in the zone and the flow status. For example, according to the number of people in the zone, step-by-step You can transmit information, that is, you can count the number of people and send it as level 1 if there are 10 people and level 2 if there are 20 people. The numbers of 10 people and 20 people are exemplary and can be changed. Alternatively, the camera ( 160 ) and/or the camera 200 may count the number of people and transmit the number of people to the server 300 , and the calculation may be performed directly in the server 300 .

The server 300 analyzes the information received from each camera 200 to instruct the robot to change its driving. to be carried out when exceeded.

driving scenario

The driving of the robot 100 follows a basic driving scenario, and the basic driving scenario may be prepared based on the following criteria. 7 is a conceptual diagram of a robot environment according to an embodiment. In FIG. 7 , one robot 100 is disposed in zones A, B, C, and D differently from FIG. 1 .

The entire driving zone is subdivided into sub-unit zones (eg, A1 to A4, B1 to B4, C1 to C2, D1 to D2 in FIG. 7), and the sub-unit zones are the average moving speed and moving distance of the robot 100 , may be set in consideration of factors affecting driving and advertisement reproduction, such as the location of a store.

When one robot 100 is operated, the basic driving route setting and the standard driving speed are determined in consideration of the replay advertisement and the main area.

When a plurality of robots 100 are placed in the same overall driving area, the time the robot 100 stays in one detailed unit area is determined, and the number of robot unit areas of each robot 100 is set for each reference time. Zones are set so that they do not overlap each other. This robot unit area is a set of several detailed unit areas, and is set for each detailed unit area residence time of the robot 100 . For example, referring to FIG. 7 , four robots 100 are disposed in the entire traveling area 12 . The robot unit area is A, B, C, and D areas. One robot is placed in each robot unit area, and each robot unit area has a plurality of detailed unit areas (A1 ~ A4, B1 ~ B4, C1 ~ C2, D1 ~ D2) may be included.

Set the sub-unit areas included in each robot unit area so that they do not overlap. The robot unit area can change over time. For example, if 4 robots are operated in 12 sub-unit areas for 10 hours per day, each robot is set as a scenario in which all sub-unit areas are driven, and each robot 100 stays in each robot unit area. If the time is 30 minutes and the robot 100 is operated at 10 am, an example in which the robot unit area is changed is as follows.

From 10:00 to 10:30, the robot unit areas are A, B, C, and D shown in FIG. 7 , and one robot is disposed and driven in each robot unit area. Referring to FIG. 7 , from 10:30 to 11:00, the robot unit areas are no longer areas A, B, C, and D, and a new robot unit area is set. For example, (C1, C2, A1, A2), (D1, D2, B1, B2), (A3, A4), (B3, B4) becomes a new robot unit area, or (C1, A1, A3) , (C2, A2, A4), (D1, B1, B3), (D2, B2, B4) can be new robot unit zones.

The change of the robot unit area is performed through the data collection and analysis program to which the AI technique is applied to various information collected while the robot 100 is operating. That is, the driving scenario is modified and supplemented based on the continuously learned information, which is transmitted from the server 300 to each robot 100 and reflected in driving.

The data to be reflected in the learning are data such as floating population/resident information in the zone by time/period, the density of people, and the robot control area for each zone. It is collected through 160.

The camera 200 for each zone transmits the density and sojourn status of people in the zone to the server 300 at regular time intervals, and the server 300 analyzes the information received from each camera 200 to analyze the information received from each robot ( 100) to control route change and advertisement arrangement change. Since each robot 100 is controlled, the robot 100 that does not receive a separate control signal among the plurality of robots 100 operates based on a pre-stored operation scenario.

In another embodiment, the camera 200 and the robot 100 in the zone A transmit the collected data to the server 300, and the server 300 controls the movement of the robot 100 through the steps shown in FIG. can decide The server 300 transmits a movement command including a movement path to the robot 100 requesting movement, and the robot 100 may move according to the movement command.

At least one of the robot 100 and the server 300 may select an advertisement to be displayed while the robot 100 is moving. That is, it is possible to select an advertisement to be displayed on a path on which the robot 100 moves and an advertisement to be displayed at a destination. For example, if it is determined that there are relatively many children on the path on which the robot 100 moves, and it is determined that there are relatively many women at the destination, the robot 100 moves on the path that the robot 100 moves, such as education, toys, etc. may display advertisements for women, and advertisements for women's cosmetics, fashion, etc. may be displayed at the destination. Also, for example, if the distance from the destination is about 0.5 to 1 meter, you can start an advertisement that matches the target. Advertisements may include promotions of specific stores.

Advertisement

* The server 300 may automatically organize advertisements requested from a plurality of companies. The server 300 sets slots for advertisements based on the number of times it receives the most advertisement requests and places different advertisements in each slot. That is, when N advertisements are requested, N slots are set and other advertisements are placed in each slot. Then, each of the N slots is arranged in a random order. Advertisements are arranged in the arranged order.

8A to 8E are tables for explaining the arrangement of advertisements according to an exemplary embodiment. Referring to FIG. 8A , a user may receive a request from a plurality of companies to transmit advertisements through the robot 100 . For example, a request may be received from four companies (company A, company B, company C, company D) to transmit advertisements through the robot 100 . A plurality of companies may request to advertise different lengths of advertisements different times. For example, Company A may request 6 45-second advertisements, Company B may request 4 30-second advertisements, Company C may request 3 40-second advertisements, and Company D may request 2 30-second advertisements from a user.

Referring to FIGS. 8A and 8B , since 6 advertisements requested by company A are the most requests, 6 slots are set and 6 advertisements requested by company A are placed in each slot. One advertisement requested by companies B, C, and D is placed in each slot sequentially. The order in which advertisements requested by companies A to D are placed in each slot may be different. That is, six slots may be set, and advertisements requested by companies B, C, and D instead of company A may be placed in each slot first. In FIG. 8A, advertisements are sequentially inserted from slot 1, but this is exemplary, and advertisements may be randomly inserted into each slot.

The server 300 may organize advertisements so that slots 1 to 6 are transmitted in an arbitrary order, respectively, and control the robot 100 so that the robot 100 transmits the automatically organized advertisements. Accordingly, all advertisements included in one slot are transmitted, and then advertisements included in the next slot are transmitted. The server 300 may arrange advertisements by randomly arranging slots 1 to 6. Accordingly, 15 advertisements may be automatically organized. In this case, when the slots 5 and 6 are consecutively arranged, the advertisement of the company A may be overlapped. When it is determined that advertisements are overlapped according to a request of an advertiser or a rule set by a user, slots 5 and 6 may not be arranged consecutively. The blanks in the slots have no advertisements placed and can be skipped. That is, in the example, the advertisement of the company C in slot 3 may be followed immediately by the advertisement of another slot. For example, in FIG. 8B, if slots 1 to 6 are sequentially arranged, the advertisement order may be based on (A-B-C-D)-(A-B-C-D)-(A-B-C)-(A-B)-(A)-(A). have.

In one embodiment, the robot 100 or the server 300 may store data for each advertisement, retrieve the stored data according to the above order, and transmit the advertisement. That is, the robot 100 stores data for each advertisement, receives an automatically organized sequence from the server 300, retrieves the stored data according to the sequence, and transmits the advertisement. Alternatively, the server 300 may display the stored advertisement data on the display 110 of the robot 100 according to the automatically organized order.

After the advertisement is auto-programmed, the advertisement may be requested from the new company. For example, a new company, Company E, may request 7 advertisements. The user simply inputs to the server 300 that Company E has requested 7 advertisements. As shown in FIG. 8C , the server 300 adds one slot (slot 7) because the number of advertisements is greater than the number of existing slots, and inserts one advertisement of company E into each slot. The server 300 automatically organizes advertisements included in slots 1 to 7 by arranging slots 1 to 7 in an arbitrary order, respectively. The blanks in the slots have no advertisements placed and can be skipped. That is, in the example, advertisement E may immediately follow company B advertisement in slot 4 . For example, if slots 1 to 7 are sequentially arranged in FIG. 8C, the advertisement order may be based on (A-B-C-D-E)-(A-B-C-D-E)-(A-B-C-E)-(A-B-E)-(A-E)-(E). . There are cases where the number of new advertisements is less than the number of existing slots. For example, a new company, Company E, may request 4 advertisements. The user simply inputs to the server 300 that Company E has requested 4 advertisements. As shown in FIG. 8D , since the number of advertisements is smaller than the number of existing slots, the server 300 inserts the advertisements of Company E into the existing slots one by one. The server 300 automatically organizes advertisements included in slots 1 to 6 by arranging slots 1 to 6 in an arbitrary order, respectively. For example, if slots 1 to 6 are sequentially arranged in FIG. 8d , the advertisement order may be based on (A-B-C-D)-(A-B-C-D)-(A-B-C-E)-(A-B-E)-(A-E)-(E). .

After the advertisement is automatically organized, the advertisement may be requested from the existing company. For example, a new company, Company B, may request three additional advertisements. As shown in Fig. 8e, the server 300 adds one slot (slot 7) because the total number of advertisements of company B is greater than the number of existing slots by one (slot 7), and the added company B in slots 5, 6, and 7 Insert one ad at a time. For example, if slots 1 to 7 are sequentially arranged in FIG. 8E, the advertisement order is (A-B-C-D)-(A-B-C-D)-(A-B-C)-(A-B)-(A-B)-(A-B)-(B). can be done with

Accordingly, the user can easily organize advertisements received from a plurality of advertisers automatically by inputting the advertisement data and the number of advertisements received from the advertisers into the server 300 .

According to an embodiment, the advertisement may be organized according to each advertisement group. For example, the advertisement group (first group) that the robot 100 transmits while moving from one place to another and in a substantially stationary state (or around the advertisement target without moving in a certain area at a certain speed or less or changing the advertising target) It can be performed by dividing into an advertisement group (second group) transmitted from (including moving from ). That is, the advertisement arrangement described with reference to FIGS. 8B to 8E for the first group and the second group may be automatically performed, respectively. For example, when inputting advertisement data into the server 300 , if metadata is input together to identify that each advertisement data corresponds to at least one of the first group or the second group, the server 300 may An advertisement may be automatically organized into a group corresponding to at least one of the first group or the second group based on the data. The metadata may be used for classifying advertisement data, for example, to identify which group the advertisement data belongs to, and which customer interests correspond.

Each advertisement group may be at least one of an advertisement company, an advertisement article, and an advertisement target. In addition, ad groups can be divided by time period. That is, the server 300 may divide the input advertisement data into a plurality of advertisement groups and organize advertisement data for each group according to the advertisement programming described with reference to FIGS. 8B to 8E .

Advertising method using robots

At least one of the robot 100 , the camera 200 , and the server 300 may reorganize the advertisement scenario of the robot 100 based on the basic advertisement programming. For example, information around the robot 100 is collected from at least one of the robot 100 or the camera 200, and based on the information, the cosmetics store cluster area displays cosmetics advertisements, and the restaurant cluster area displays restaurant advertisements. It can be transmitted with priority irrespective of the order in which advertisements are organized. Advertisements transmitted before the existing order can be deleted or skipped from the existing advertisement arrangement order or slot.

In addition, hourly, daily, weekly, and monthly advertisement transmission details according to the operation of the robot 100 may be recorded, and advertisements may be reorganized based on this. For example, by collecting which advertisements are preferentially transmitted by hour and by day, which advertisements can keep people's eyes for a long time, and the like, advertisements may be reorganized based on the collected information. In addition, data such as the floating population of the area in which the robot 100 operates, the number of people staying, and distribution by gender/age are continuously collected from the camera 160 of the robot 100 or the camera 200 disposed in the area, and based on this Ads can be periodically revised and supplemented. Also, the server 300 may organize advertisements according to the interests of the customers. The customer's interests may be collected via the Internet or entered by the user.

At this time, the advertisements are organized so that the number of advertisements transmitted within a unit period (day, week, month, etc.) is equal to the number of advertisements received from the advertiser.

In an embodiment, different advertisements may be transmitted according to time zones. The camera 160 of the robot 100 and the camera 200 disposed in the area are the customer's gender, age, and composition (single customer, couple customer, family customer, friend, student, office worker, etc.) for time and area of the indoor shopping mall. ) may be collected and transmitted to the server 300 by collecting data on the above-described customer information including. Accordingly, the server 300 may determine which customer visits relatively more for each time zone. The server 300 may also determine which customers visit the most on weekdays and weekends, or on each day of the week. For example, the robot 100 may be controlled to transmit advertisements according to the student's interests, such as advertisements related to at least one of education, employment, and self-development, during a time period frequented by students. The robot 100 may preferentially transmit restaurant advertisements during a preset meal time. In a time period where many families visit (eg, when it is determined that there are many families on the weekend), the robot 100 may be controlled to preferentially transmit advertisements related to the interests of the family relative to other time periods. In order to transmit different advertisements for each time period, the robot 100 or the server 300 may select at least one advertisement from the above-described advertisement group. That is, the advertisement group is classified into a family advertisement group, a restaurant advertisement group, a student advertisement group, a male advertisement group, a female advertisement group, etc., and the robot 100 or the server 300 is included in the advertisement group corresponding to the corresponding time zone. At least one advertisement may be selected and transmitted. The server 300 may store the time when the advertisement is transmitted and use it as analysis data later.

In an embodiment, the robot 100, the camera 200, or the server 300 may control the robot 100 to transmit an advertisement according to a predetermined advertisement schedule. An embodiment of the predetermined advertisement programming is the same as described above. In order to transmit a predetermined advertisement schedule, the robot 100 may autonomously move to find the target of the advertisement. For example, the robot 100 transmits advertisements according to the arrangement of (A-B-C-D)-(A-B-C-D)-(A-B-C)-(A-B)-(A)-(A), which is an example of the advertisement arrangement sequence described with reference to FIG. 8B . controlled to do By using the camera 160 and/or the camera 200 of the robot 100, the robot 100 searches for the advertisement target of A and transmits the advertisement. While sending A, find the advertisement target of B, and after the advertisement A ends, find the advertisement target of B and send B. While moving to find the advertisement target of B, the advertisement included in the advertisement group (the first group) transmitted while moving from one place to another may be transmitted. In this way, it is possible to improve the attention and efficiency of advertisements by finding and performing advertisements according to the organized advertisement order.

In one embodiment, the robot 100, the camera 200, or the server 300 may control the robot 100 so that the robot 100 transmits an advertisement according to the surrounding advertisement target. The robot 100 transmits advertisements based on a predetermined advertisement schedule, but preferentially displays advertisements corresponding to the interests of people around the robot 100 using the camera 160 and/or the camera 200 of the robot 100 . can be sent For example, while transmitting A in the sequence (A-B-C-D), if it is determined that the main interest of the people around the robot 100 is C as a result of analyzing the people around the robot 100, C may be transmitted after the advertisement A ends. Unlike the existing order, even when advertisements according to the interests of people around the robot 100 are first transmitted, the robot 100 is controlled so that the number of transmitted advertisements is the same as the number of advertisements received from the advertiser. For example, in the sequence (A-B-C-D)-(A-B-C-D)-(A-B-C)-(A-B)-(A)-(A), after continuously determining that the interests of the people around you are C and advertising C three times, Even if people's interest is again determined to be C, another advertisement is sent without advertising C. At this time, the robot 100 or the server 300 may control the robot 100 to search for an advertisement target of an advertisement other than C and transmit the advertisement. In addition, it is possible to record in the server 300 that there are many customers interested in the advertisement of C to notify the user.

In an embodiment, the robot 100 may include a four-sided display 110 as shown in FIG. 3 . The robot 100 may individually control the four-sided display 110 . The robot 100 may be controlled to transmit different advertisements according to the information of the person in front of each of the four-sided displays 110 .
