STEUERSYSTEM FUER AUTOMATEN MIT DIREKTANLEITUNG UND NACHVOLLZUG

摘要

A control system for a direct teaching/playback type robot, including a low spring constant member connected to a drive source for driving a robot element through a frictional coupling. The control system basically includes a first incremental position detector provided between the robot element and the frictional coupling for detecting the rotational position of the robot element, a second incremental position detector connected to the drive source for detecting the rotational position of the drive source, and a switch for selectively connecting the output terminals of the first and second position detectors to a drive source controller in teaching and playback modes of operation, respectively.
