<p>A moving component of a robot, such as a robot arm, is controlled to return from a given position (D) to an original point (A) after the moving component has traced paths established respectively by a group of successive motion data blocks (1,2,3,4) including positional data representative of positions of the moving component. The moving component is moved on the basis of positional data in one of the motion data blocks which precedes a present position of said moving component, and then is moved on the basis of positional data in one of said motion data blocks which precedes said first-mentioned one of the motion data blocks. Therefore, the moving component is moved successively backwards along the paths based on the positional data in the motion data blocks (1,2,3,4). </p> |
