An adjustable gripping assembly having a first or holding end with a trigger assembly rotatably held therein and connected to a wind assembly having a flexible, non-resilient link held by one end therein for operating a pair of gripping elements, movably mounted on a distal end of an adjustable, multipart hollow body. The trigger assembly including a trigger lock thereon and the multipart body including telescoping locking element mounted on the telescoping joints to control adjustment of the length of the assembly when the portions of the multipart body are moved with respect to each other. And, a pivot joint formed on an outer end of the multipart body, adjacent the pair of gripping elements to allow the gripping elements to be pivoted to different angles on the outer end upon release of a locking element held in the pivot joint.

The present disclosure relates to a 4D printed gripper with flexible finger joints and a trajectory tracking control method thereof. The 4D printed gripper with flexible finger joints includes: a palm unit and five finger units connected to the palm unit, where each finger unit includes two flexible finger joints and two phalanges; each flexible finger joint is divided into one upper layer and one lower layer of liquid crystal elastomer (LCE), and each LCE is used to implement a bidirectional bending movement of the finger unit. The present disclosure can precisely control the gripper with flexible finger joints.

The present disclosure relates to a robotic gripper comprising a body and two robotic fingers mounted to the body. Each robotic finger includes a first link, a second link, a third link, a fourth link, a first joint, a second joint and a third joint. The first joint connects the first link and the second link, and the second joint connects the second link and the third link, and the third joint connects the third link and the fourth link. These links and these joints are comprised of elastic material and are formed in one piece.

The present invention will provide a device in which the gripping action is achieved by a compliant membrane manipulated by electromagnetic forces. The gripping force provided by the present invention is best suited for delicate objects, as it gently applies the gripping force necessary for displacement. This is accomplished through a chamber, a membrane, a plunger attached to the membrane, and a solenoid configured to manipulate the plunger, and thus, the membrane.

According to one embodiment, a gripping tool includes a gripper. The gripper is flexible. A granular material is provided in an interior of the gripper. The gripper is configured to grip a workpiece by being in close contact with the workpiece in a state in which an outer perimeter of the gripper is held, and by the interior of the gripper being depressurized.

The invention relates to a gripping finger (1) for an adaptive gripping device (10), comprising a first strip element (2) and a second strip element (3), which are flexible, and a plurality of spacing elements (7, 13, 16), which are arranged between the first strip element (2) and the second strip element (3). A first end (8) of each of the spacing elements (7, 13, 16) is movably connected to the first strip element (2) and an opposite second end (9) of each of the spacing elements (7, 13, 16) is movably connected to the second strip element (3). At least one of the spacing elements (7, 13, 16) is designed as a curved spacing element (13), the curved spacing element (13) having a predefined curvature.
