Abstract
A gripper assembly contains within its cylindrical tubular housing a piston and a rotatably supported finger assembly having a push rod and gripper fingers. The push rod is pressed rotatably against the piston through a thrust bearing by a spring. As the piston pushes the push rod against the biasing force of the spring, the motion of the push rod causes the gripper fingers to close. Position of the object to be gripped can be detected through a fiber optic light guide passing through the piston and the push rod.
