Abstract
An apparatus and method having short stroke motion for gripping and releasing an object utilizes a programmable stepper motor for controlling various short stroke, generally arcuate motions of the gripper. Gears associated with each of the at least one gripper jaws supported on a carrier shaft engage a common ring gear that is driven by drive means including the stepper motor which imparts synchronous motion of the grippers for opening and closing about the object.
