A remote manipulator for radiation cells and the like. This device is an all electric manipulator for hazardous environments to follow the basic movements of the operator but to provide features to provide extended use of the manipulator beyond the capabilities of the operator when necessary or desired. Identical arm units are removably positioned on opposite sides of a torso to make up the slave unit. Joints in the arms are enclosed in rotable boots. By being identical, the arms may be attached to either side of the torso as well as necessitating fewer replacement parts. The motion of each of the arms is sufficient such that essentially any position of one arm relative to the other arm can be achieved. Many components are interchangeable. Electrically controlled pan/tilt heads mounted on the torso support video cameras to permit remote viewing. A unique control system is utilized to interact between the slave unit and the master unit to accomplish the range of motions to the slave unit that may be desired for any particular application. The subcomponents of each of the arms may be removed for replacement and/or maintenance operations. Electrical connection between each major component attached to the torso is made as part of the junction of the components. Thus, the only exterior cable is that between the torso and the control system.
