ABSTRACT:
A remote handling manipulator having a slave arm and a manually operated controller with a grip mechanism, is provided with a force feedback system to impose a force resisting operation of the grip mechanism related to a load experienced by the slave arm. A jaw mechanism of the slave arm is operated by a pressurized fluid, and in the system the pressure of the fluid and the effort exerted by the grip mechanism are compared to produce an error signal used for regulating the force applied to the grip mechanism.
