Abstract: An outer cylindrical housing mounts a control shaft coaxially extending upwardly from the housing through a top plate. A ratchet bracket is mounted to the control shaft above the top plate, with a drive end extending above the ratchet sprocket for reception within a handle to effect rotation of the control shaft. A plurality of encircling straps are mounted to the control shaft spaced apart ninety degrees at an annular orientation relative to one another, with an encircling strap of each of the encircling straps extending through a slot through the outer housing. Each slot is arranged in a parallel relationship relative to one another in an annular configuration. Rotation of the control shafts effects winding of the encircling straps about the control shaft for their clamping about a drum member.

Abstract: An end effector suitable for use on a robotic arm associated therewith and coupled to a computer includes a universal mounting plate permitting the end effector to be mounted on the distal end of a robotic arm; a gripper mechanism slideably retained within the end effector is responsive to electronic command signals permitting the finger members disposed therein to acquire, lock and release, a plurality of tools and components upon receiving computer controlled electronic command signal. The electronic command signal controls the driving power from a power source which is coupled to the end effector.
