ABSTRACT:
The invention relates to a method and an apparatus for operating an industrial robot, for the accurate processing of workpieces, especially during spot-welding, wherein coordinates of processing points or lines are preselected according to a program and an actual position of a processing point is detected by a sensor carried by the robot hand, the difference between the actual position and a desired position being determined, and the correction of all coordinates of the operating points by the difference in position being carried out in accordance with this determination.
