A pivoting mechanism at the end of a robotic arm permits picking up parts from the end of a gravity fed track. It also permits placing of parts up and underneath or at angles less than the horizontal when combined with the rotational capability of a standard robot. Additionally, it permits pivoting of a carried part while the manipulator is in motion. The design incorporates snap-on and snap-off air disconnects, two thrust bearing, two torsion springs, and double acting air vanes. Figure 1 shows a left side view of the mechanism rotated to a fully clockwise position, with the left air vane cover and gripper removed. This view shows air ports A1 and A2, as well as air ports B1 and B2 which can be energized to drive the vane in a clockwise or counterclockwise direction.
