Abstract
Application of tension simultaneously to three cords extending through respective coil springs and attached off the axes of the springs causes movement of tactile members on the ends of the springs to grasp, lift and rotate a workpiece. A capacity sensitive sensor positions the coil assembly relative to the object so that the tactile members will grasp the workpiece in a uniform manner irrespective of workpiece size.
