Abstract
Systems and methods to grasp objects using vacuum-actuated end of arm tools may include extending pistons and suction cups. For example, responsive to application of negative pressure, a piston may move from a retracted position to an extended position. In addition, responsive to grasping an object by a suction cup, the piston may remain in the extended position due to continued generation of pressure differentials that apply forces to the piston toward the extended position. Alternatively, a piston may be biased toward an extended position due to a spring force, and may remain in the extended position responsive to grasping an object. In the extended position of the piston, an object may be grasped with an amount of passive compliance to external forces that may be applied to the object.
