Abstract
The hand of a robot is moved from an instant position P.sub.1 to a first command position P.sub.2 to grip one of the workpiece W.sub.1,W.sub.2,W.sub.3 placed at the first command position and conveys the same to a second command position P.sub.3. A sensor is contacted by the workpiece when the hand takes an intermediate position Px on its way from the instant position P.sub.1 to the first command position P.sub.2, the robot control system stops the hand without delay or after travel of the hand over a predetermined distance and, after the travel of the hand over a predetermined deceleration distance, stops the hand. The hand is then moved from the stopping position to the second command position P.sub.3 neglecting the remaining stroke or movement between the stopping position and the first command position.
