Mechanical detents are placed on a workpiece to supplement a robotic positioning mechanism and to accurately position a robot arm for the precision placement of parts. The mechanism works as described in the following. As seen in the drawing, gripper pins 1 are attached to a gripper 2 with a means of gripping (not shown) a part 3, which is to be moved. The pins 1 have a V-post shape to facilitate mating with corresponding V-block-shaped-supply/delivery pins 4. The parts 3, which are to be moved, are placed over supply/delivery pins 4 by means of slots in the part 3. The gripper 2 is attached to a robot (not shown) such that it can be moved in any direction. A pin mounting frame 5 provides a rigid form so that the gripper pins 1 are held in a secure position.
