In a typical automated assembly line, workpieces are transport within a production cell, by robots equipped with grippers. Generally the sole function of the gripper is to hold the workpiec as the robot loads/unloads it at a required location, and then releases it. The "required location " frequently is a work-station fixture, which clamps/releases the workpiece being loaded/unloaded. The work-station fixture clamping mechanism is usually actuated by an integrated device such as an air cylinder. In a particular embodiment, at any given moment in one specific production cell, there are in excess of forty work-pieces, under test, clamped in individual fixtures. Individual work-pieces are sequentially loaded/unloaded by robot, at intervals necessary to sustain a required production rate.
