ABSTRACT:
Disclosed is a manipulator which is particularly suitable for tapping a furnace. The manipulator includes an elongate arm which is axially reciprocable and rotatable in a vertical and a horizontal plane, and a handle for operating the arm for its axial reciprocal movement and vertical or horizontal rotation. The manipulator is particularly characterized by the provision of a bilateral servo system interconnecting between the arm and the handle for feeding back to the handle any variation in the force acting on the arm under operation.
