Abstract
A suction-cup end effector conforms to and grasps objects upon application of vacuum force. The suction cup assembly can have isotropic stiffness in a plane defined by a contact surface of the suction cup assembly and thus can conform regardless of the orientation of the suction cup to the object. The suction cup includes a foam suction cup body, a thin structural ring to provide a spring bias toward a rest position, and a sealing membrane within the structural ring to seal the suction cup.
