Abstract
In a robot controller, return of a position (including posture) of a robot arm to an origin thereof is controlled along a searched return path, when there occurs an abnormality against the robot. It is determined whether there is a trajectory portion regarded as being a straight line on a motion trajectory of the arm, based on the operation log data recorded in a recording unit when it is determined that the arm should be returned to the origin. Operation log data of a node are decimated (i.e., downsampled), which are present between two nodes which are at both ends of a trajectory portion regarded as being a straight line when the trajectory portion is regarded as being the straight line. Then, the return path is calculated, along which the arm returns to the origin, based on remaining operation log data.
