Abstract
A robotic tool coupling system includes a first connecting unit including a piston movable along a longitudinal axis. The piston includes a multifaceted contact surface comprising a tapered locking surface; an initial actuating surface having an angle with respect to the axis not greater than the angle of the tapered locking surface; and a failsafe surface interposed between the tapered locking surface and the initial actuating surface. The system includes a second connecting unit having a plurality of rolling members disposed in a retention chamber including at least one angled surface operative to lock the first and second units together when the rolling members are forced against the angled surfaces by the tapered locking surface. The piston contact surface may additionally include a step surface, generally normal to the longitudinal axis, and a retention surface generally parallel to the axis.
