A gripping mechanism according to the present invention is provided with: two gripping pieces pivoted about a pivoting axis; a gripper main body that supports the gripping pieces at a distal-end portion; a pulley that is supported about a rotation axis that is parallel to the pivoting axis; an opening wire that is wound around the pulley that has one end secured to the gripping pieces or the gripper main body, and that causes tensile forces that cause the rotation axis to be moved in one direction pulley, wherein the pulley is disposed so that a resultant force of the tensile forces in the opening wire that acts on the rotation axis becomes greater than the pulling force, and so that a moment that causes the gripping pieces to be pivoted in the directions in which the gripping pieces are opened relative to each other is generated.

A finger mechanism includes a base portion and a plurality of finger portions supported by the base portion, wherein each of the finger portions includes a first bone member, a second bone member rotatably coupled to one end portion of the first bone member, and a pair of third bone members each being rotatably coupled to another end portion of the first bone member and the base portion, and forming a parallel link mechanism between the first bone member and the base portion.

The invention provides a multi-degree-of-freedom instrument for robot, which comprises an instrument base, an instrument rod and an instrument pliers head, wherein one end of the instrument rod is rotatably arranged on the instrument base, the instrument rod can rotate around a central axis of the instrument rod, the instrument pliers head is hinged to the other end of the equipment rod, and the instrument base can drive the instrument pliers heads and the equipment rod to act. The invention has the advantages of multiple degrees of freedom, high flexibility and high reliability.

A robotic surgical instrument comprising a shaft, an articulation attached to the distal end of the shaft, and a driving mechanism at the proximal end of the shaft. The articulation comprises a plurality of joints for articulating an end effector, the plurality of joints driveable by at least first and second pairs of driving elements. The driving mechanism comprises a pulley arrangement and a pulley drive. The pulley arrangement comprises first and second pulleys attached together such that their separation is fixed, wherein the first pair of driving elements is constrained to move around the first pulley, and the second pair of driving elements is constrained to move around the second pulley. The pulley drive is configured to linearly displace the pulley arrangement, such that a linear displacement in one direction away from the distal end of the shaft causes the first pair of driving elements to be tensioned and the second pair of driving elements to be de-tensioned, and a linear displacement in an opposing direction towards the distal end of the shaft causes the second pair of driving elements to be tensioned and the first pair of driving elements to be de-tensioned.

An end effector for use and connection to a robot arm of a robotic surgical system, wherein the end effector is controlled and/or articulated by at least one cable extending from a respective motor of a control device of the robot surgical system, is provided. The end effector includes a wrist assembly, and a jaw assembly. The jaw assembly includes a cam pulley rotatably supported on at least one support plate of the jaw assembly, wherein the cam pulley is operatively connected to a proximal end of each of the jaws of the jaw assembly such that rotation of the cam pulley results in one of an opening and closing of the jaw assembly.

Compliant manipulators are provided, in which the manipulators include a plurality of slideably interlocked filaments each having a proximate end and a distal end. The interlocked filaments can be formed from a flexible material. The compliant manipulators can also include at least one filament-actuating device operatively connected to the respective distal ends of the plurality of slideably interlocked filaments. The at least one filament-actuating device can be manipulated directly or remotely to push and/or pull the respective filaments to impart a desired movement to the manipulator. The stiffness or flexibility of the manipulators can also be controlled to provide varying degrees of stiffness during use.

A gripping mechanism includes: two gripping pieces pivoted relative to each other about a pivot axis; a base supporting at least one of the gripping pieces; a pulley rotatably supported about a rotation axis parallel to the pivot axis; a wire wound around the pulley, causing tensile forces that move the rotation axis in one direction to act, and transmitting a pressing force; and a force-receiving portion receiving the pressing force. The pulley is disposed so that a resultant force of the tensile forces of the wire acting on the rotation axis generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be closed. The force-receiving portion is disposed so that the pressing force applied from the wire generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be opened.

The embodiments described herein can be used in a variety of grasping, cutting, and manipulating operations. In some embodiments, an apparatus includes a first joint member, a second joint member, and a flexure. The first joint member includes a first connection portion and a contact surface. The second joint member including a second connection portion. A first end portion of the flexure is coupled to the first connection portion, and a second end portion of the flexure is coupled to the second connection portion. The flexure is configured to deform elastically when the first joint member and the second joint member move from a first configuration to a second configuration. When in the first configuration, the central portion of the flexure is spaced apart from the contact portion. When in the second configuration, the central portion of the flexure contacting the contact portion.

Devices, systems, and methods for autonomously separating and sorting a plurality of individual articles from a pile of laundry articles into two or more sorted loads for washing are described. For example, an autonomous sorting and separating system includes a stationary surface configured to receive thereon at a first location the pile of laundry articles. A plurality of actuatable grippers are disposed at spaced apart positions adjacent the stationary surface and comprise a first actuatable gripper configured to grasp, hoist, and deposit at a second location at least one of the plurality of individual articles within reach of a second actuatable gripper. A terminal gripper comprising at least one of the second actuatable gripper and another actuatable gripper is configured to release an individual article into one of the two or more sorted loads. At least one controller is in operable communication with the grippers.

A gripping mechanism according to the present invention is provided with: two gripping pieces pivoted about a pivoting axis; a gripper main body that supports the gripping pieces at a distal-end portion; a pulley that is supported about a rotation axis that is parallel to the pivoting axis; an opening wire that is wound around the pulley that has one end secured to the gripping pieces or the gripper main body, and that causes tensile forces that cause the rotation axis to be moved in one direction pulley, wherein the pulley is disposed so that a resultant force of the tensile forces in the opening wire that acts on the rotation axis becomes greater than the pulling force, and so that a moment that causes the gripping pieces to be pivoted in the directions in which the gripping pieces are opened relative to each other is generated.
