Abstract: A charging robot includes a memory storing computer-executable instructions, at least one processor that accesses the memory and executes the instructions, an output device, and a first position recognition device that identifies a vehicle approaching a charging specification. The processor determines at least one of a first distance between the vehicle identified by means of the first position recognition device and the charging robot, a first movement direction of the vehicle, or a first movement speed of the vehicle, or any combination thereof and charges the vehicle, based on that a position of the vehicle is included in a charging position which is a position at which the charging robot is able to charge the vehicle, based on the at least one of the first distance, the first movement direction, or the first movement speed, or the any combination thereof.

Abstract: A guide robot can include a position recognition device configured to recognize a position, an image recognition device configured to recognize a user from a target image, a behavior controller configured to transmit to a content recommendation device a request for generating a target contents list in which a position of the guide robot and a characteristic of the user are reflected, and outputs the target contents list through an output device of the guide robot, and the content recommendation device is configured to combine the position with map information to generate first feature data, generate second feature data about the characteristic of the user from the target image, and transmit to the behavior controller the target contents list obtained by applying each of the first feature data and the second feature data to a content recommendation model.

Abstract: A robot control system and a method may be operated in a microservices architecture (MSA)-based control environment. The robot control system includes an application programming interface (API) gateway that connects an authentication server for authenticating a robot, a management server for managing the robot, and an operation server for operating the robot in a Hyper Text Transfer Protocol (HTTP) communication method and an administrator terminal that communicates with the robot through WebRTC (Web Real-Time Communication).

Abstract: A surveillance system is provided. The surveillance system includes: a first frequency communication module configured to receive a first surveillance image from a first camera, and receive a second surveillance image from a second camera; a second frequency communication module configured to receive second frequency communication module notice information from the second camera; and a processor configured to change a reception signal gain value of the first frequency communication module based on the second frequency communication module notice information, wherein a reception signal strength of the first surveillance image is different from a reception signal strength of the second surveillance image.
