  • Safety device in an operating unit for an industrial robot
    Patent number: 4535207
    Abstract: An operating unit for an industrial robot is provided with hand-sensing device arranged in such a way that, when an operator operates the robot with the aid of a joystick, the operator's hand rests on the hand-sensing device enabling the joystick to be operated with the fingers of the same hand. Suitably the hand-sensing device includes a plate and a transducer sensing the presence of the operator's hand when it rests on the plate. The transducer influences a control unit which only allows the joystick to influence the robot when a hand is sensed by the hand-sensing device when the hand rests on the plate.
