ABSTRACT:
A robot hand device is provided with a collision protection coupling between a protective plate holding the hand device and a base plate mounted on the robot arm. When the hand device collides against an object in its surroundings, spring biased balls are disengaged from the recesses of a tapered pin of the protective plate by the impact of the collision so that the tapered pin comes away from a tapered hole of the base plate and the protective plate is uncoupled and suspended by a coupling chain to prevent damage.
