Abstract

A control system for controlling a plurality of robots using artificial intelligence includes a communication unit configured to receive user information of each of a plurality of unit zones in which the plurality of robots is disposed, and a processor configured to calculate a plurality of densities respectively corresponding to the plurality of unit zones based on the user information of each unit zone, calculate average densities of a plurality of group zones using the plurality of calculated densities, determine respective priorities of the plurality of group zones based on the calculated average densities, and control movement of one or more of the plurality of robots based on the determined priorities.

First claim

The invention claimed is:

1. A control system for controlling a plurality of robots using artificial intelligence, the control system comprising:
a processor configured to:
access user information for each of a plurality of unit zones in which the plurality of robots are disposed, wherein the user information includes voice data collected in each of the plurality of unit zones,
calculate a plurality of densities, respectively that corresponds to the plurality of unit zones based on the user information for each unit zone,
calculate average densities of a plurality of group zones using the plurality of calculated densities,
determine respective priorities of the plurality of group zones based on the calculated average densities, and control movement of one or more of the plurality of robots based on the determined priorities,
extract a plurality of frequency bands from the voice data of each unit zone,
acquire the number of the plurality of frequency bands extracted as the number of users for each unit zone, and
acquire the number of users as a density of each unit zone.

2. The control system according to claim 1 ,
wherein each of the plurality of group zones includes some of the plurality of unit zones, and
wherein the processor is configured to transmit a command for moving the one or more robots to a group zone with a highest priority among the plurality of group zones.

3. The control system according to claim 2 , wherein the processor is configured to give higher priority to a group zone with a larger average density.

4. The control system according to claim 1 , wherein the processor is configured to set a movement path on which the one or more robots will move based on the determined priorities, and transmit a command for moving the one or more robots on the set movement path.

5. The control system according to claim 4 , wherein the processor is configured to transmit a command for moving the one or more robots from a group zone with high priority to a group zone with low priority.

6. The control system according to claim 1 , further comprising a memory configured to store position information of the plurality of group zones,
wherein the processor is configured to control movement of the one or more robots using the priorities and the position information.

7. A method of operating a control system for controlling a plurality of robots using artificial intelligence, the method comprising:
receiving user information for each of a plurality of unit zones in which the plurality of robots are disposed, wherein the user information includes voice data collected in each unit zone;
calculating a plurality of densities, respectively, that correspond to the plurality of unit zones based on the user information of each unit zone;
calculating average densities of a plurality of group zones using the plurality of calculated densities;
determining respective priorities of the plurality of group zones based on the calculated average densities; and
controlling movement of one or more of the plurality of robots based on the determined priorities,
extracting a plurality of frequency bands from the voice data of each unit zone,
acquiring the number of the plurality of extracted frequency bands as the number of users of each unit zone, and
acquiring the number of users as a density of each unit zone.

8. The method according to claim 7 ,
wherein each of the plurality of group zones includes some of the plurality of unit zones,
wherein the controlling includes transmitting a command for moving the one or more robots to a group zone with a highest priority among the plurality of group zones.

9. The method according to claim 8 , further comprising giving higher priority to a group zone with a larger average density.

10. The method according to claim 7 , further comprising:
setting a movement path on which the one or more robots will move based on the determined priorities; and
transmitting a command for moving the one or more robots on the set movement path.

11. The method according to claim 10 , further comprising transmitting a command for moving the one or more robots from a group zone with high priority to a group zone having low priority.
