Abstract
A mechanically intelligent end-of-arm tool includes a valve that is actuated by the action of the arm, such that a force applied to the object to be grasped opens the valve to expose a suction cup to the vacuum pressure. A spool valve, poppet valve, and butterfly valve, et al., can perform the valve function. The tool may include a button that has a rigid contact surface or may be deformable to provide a smoothing force to the object.
