1. A manual robotic tool changer, comprising: a first unit operative to be attached to one of a robot and a robotic tool; a second unit operative to be attached to the other of the robot and a robotic tool, and further operative to be selectively coupled to and decoupled from the first unit; a plurality of ball members disposed in the first unit; a rotating cam surface ring disposed in one of the units and operative to engage the ball members in the first unit and to urge the ball members, by rotational movement of the rotating cam surface ring, against a coupling surface of the second unit to lock the first and second units together; a handle operative to rotate the cam surface ring to couple and decouple the first and second units; and a one-way clutch mechanism operative to allow rotation of the cam surface ring in the coupling direction and to restrict rotation of the cam surface ring in the decoupling direction unless by actuation of the handle.
