Abstract: The present disclosure relates to flexible vacuum fastener gripping attachment for a screwdriver and an adjustable screw feeder operable to provide screws to an automatic screwdriving unit. The flexible vacuum fastener gripping attachment may be made of flexible material and may be operable to surround a bit of an automated screwdriving unit while a vacuum is communicated to the gripping attachment. The fastener feeder may be easily adjusted to different types and/or sizes since it may be adjusted by rotating a thumb screw accessible from the outside of the casing of the fastener feeder while the fastener feeder is operating.

Abstract: A gripper may include a plate, a suction manifold, one or more attachment mechanisms, and one or more suction cups. The plate may have a body and one or more extremities and each extremity may have one or more slots formed therethrough. The suction manifold may be connected to the body of the plate. The one or more suction cups may each be attached to the plate via one of the attachment mechanisms and may be fluidly connected to the suction manifold. The attachment mechanisms may each extend through one of the slots of the plate. Each attachment mechanism may be configured to be tightened, loosened, and repositioned by hand.

Abstract: In one aspect, the present disclosure provides a robot gripper with a closing mechanism that while providing a desirable closing speed avoids exerting a force on the rigid object which is greater than the holding force required to hold the rigid object in the gripper. In another aspect, the present invention provides a robot gripper capable of detecting a slip or loss of an object held by the gripper. In an alternative aspect, the present invention provides a robot gripper capable of being hand guided. In another aspect, the invention provides a robot gripper brake drive circuit with faster operation. In one other aspect, the invention provides a connector for connecting a robot end effector to a robot arm with an adjustable cable.
