Abstract: A robot motion data processing system has a data extraction module for intermittently extracting restoration motion data from a successive input motion trajectory formed for controlling a motion of a robot, and a data restoration module for restoring an output motion trajectory approximate to the input motion trajectory by using restoration motion data extracted from the data extraction module. The output motion trajectory is restored to satisfy a condition that the robot operating according to the output motion trajectory does not exceed a hardware operation limit of the robot.
