Robot server for controlling robot, system having the same for providing content, and method thereof

A content service system for providing content service to a robot, the system comprising:

• a content server (CServer) arranged to store a plurality of contents and the CServer arranged to transmit a requested content data (RCData) when content service is requested;
• and
• a robot server (RServer) arranged to receive a request for the content service (RCService) from the robot, the RServer arranged to connect to the CServer, the RServer arranged to receive the RCData, and the RServer arranged to transmit the RCData to the robot, wherein the RServer comprises:
• a virtual robot object manager (VROM) arranged to generate a virtual robot object (VRO) in correspondence to the robot and the VROM arranged to activate the VRO when the VROM is connected to the robot;
• and
• the VRO arranged to analyze the RCService received from the robot, to transmit the RCService to the CServer, the VRO arranged to receive the RCData from the CServer, and the VRO arranged to transmit the RCData to the robot, wherein the VRO comprises:
• a robot proxy (RProxy) arranged to include a communication protocol and data processing scheme according to a type of the robot, and the RProxy arranged to communicate with the robot;
• and
• a virtual object executing unit (VOEU) arranged to transmit the RCService received through the RProxy to the CServer, the VOEU arranged to receive the RCData from the CServer, and the VOEU arranged to transmit the RCData to the robot, wherein the VOEU provides corresponding content data to the robot when a predetermined condition is satisfied even when there is no RCService from the robot.

A method of providing content service to a robot from a content service system, the method comprising:

• receiving a request for content service (RCService) from the robot at a content server (CServer) of the content server system in which the CServer is arranged to store a plurality of contents;
• transmitting from the CServer to a robot server (RServer) a corresponding requested content data (RCData) when the RCService is requested;
• transmitting from the RServer to the robot the RCData, wherein the RServer comprises:
• a virtual robot object manager (VROM) arranged to generate a virtual robot object (VRO) in correspondence to the robot and the VROM arranged to activate the VRO when the VROM is connected to the robot;
• and
• the VRO arranged to analyze the RCService received from the robot, to transmit the RCService to the CServer, the VRO arranged to receive the RCData from the CServer, and the VRO arranged to transmit the RCData to the robot, wherein the VRO comprises:
• a robot proxy (RProxy) arranged to include a communication protocol and data processing scheme according to a type of the robot, and the RProxy arranged to communicate with the robot;
• and
• a virtual object executing unit (VOEU) arranged to transmit the RCService received through the RProxv to the CServer, the VOEU arranged to receive the RCData from the CServer, and the VOEU arranged to transmit the RCData to the robot, wherein the VOEU provides corresponding content data to the robot when a predetermined condition is satisfied even when there is no RCService from the robot.
