  • Patent number: 10341413
    Abstract: Provided are a method and system for synchronizing a robot with a server. The service sends a time service command including a current time of the server to the robot, and the robot receives the time service command, so as to enable time synchronization of the robot with the server. A control device receives first command data carrying a first timestamp sent from the server, and then determines whether the first timestamp in the first command data has expired. If the first timestamp has expired, the control device receives command data resent from the server until second command data carrying an unexpired second timestamp is received. Finally, the control device controls the robot to execute a corresponding action at a time corresponding to the second timestamp based on the second command data, so as to realize the synchronization of the robot with the command data sent from the server.
