  • Patent number: 11573140
    Abstract: This invention relates to force/torque sensor and more particularly to multi-axis force/torque sensor and the methods of use for directly teaching a task to a mechatronic manipulator. The force/torque sensor has a casing, an outer frame forming part of or connected to the casing, an inner frame forming part of or connected to the casing, a compliant member connecting the outer frame to the inner frame, and one or more measurement elements mounted in the casing for measuring compliance of the compliant member when a force or torque is applied between the outer frame and the inner frame.

  • Publication number: 20220184818
    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.

  • Publication number: 20210213607
    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.

  • Patent number: 8973958
    Abstract: A mechanical gripper being adapted to automatically perform a stable pinch grasp and an encompassing grasp and a method of determining a system geometry thereof. The gripper comprising at least one mechanical finger comprising. The at least one mechanical finger comprising a first phalanx and a second phalanx that are pivotally connected. When a load is applied on a stable pinch grasp region, an actuation mechanism is adapted to allow the second phalanx to translate and allow its contact surface to maintain a constant orientation in order to automatically perform a pinch grasp, when a load is applied on the first phalanx or below the stable pinch grasp region, the actuation mechanism is adapted to allow the second phalanx to pivot and automatically perform an encompassing grasp.
