Abstract

Robot joint with an electric drive motor (30), a limit switch (36) for a safety shut off of the same, and a sensor (100) for the zero position-scanning of the joint. The limit switch (36) is actuated by annular segment like platform pieces (50) which are securable in different angle positions on a front face of the one robot part (12). For this purpose, a divided support ring (72,74) is provided which is securable in different angle positions independent from the platform pieces (50) and which has a side face (96,98) which influences the sensor (100).
