A system for harvesting berries comprising a tendon-driven gripper having fingers made of a compliant material.

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.

Prosthetic hand (1) with a wrist (13) and provided with a hand palm (2) and fingers (4) attached to the hand palm (2), wherein the hand palm (2) and fingers (4) comprise bars (5) and joints (6) connecting the bars (5) forming a construction (7) supported by the wrist (13), wherein said bars (5) occupy a position with reference to each other de-pending on an external load applied to the construction (7), wherein a reaction force for said load applied to the construction (7) is provided by or through the wrist (13), and wherein the construction (7) has an unloaded position wherein the fingers (4) are stretched and a plurality of loaded positions corresponding to loads applied to an inner side of the hand (1) wherein the construction (7) is deflected from the unloaded position wherein the fingers (4) are stretched into a series of loaded positions in which the fingers (4) are flexed into increasingly bonded positions so as to eventually close the hand (1), and that said construction (7) is provided with a locking mechanism (9) to lock the construction (7) in one of the plurality of loaded positions.

A gripping device for handling sample containers is presented. The gripping device comprises a number of rigid fingers having non-gripping surfaces adapted to reduce adhesion between the non-gripping surfaces and labels. The number of rigid fingers collectively grip a sample container. Each finger comprises a gripping surface to contact the sample container while the sample container is gripped by the gripping device. The non-gripping surface of each finger is different from the gripping surface. The non-gripping surface of at least one of the fingers is at least partially corrugated. A sample container processing system comprising such a gripping device is also presented.

A robot hand includes three or more holding portions arranged at intervals from each other along a circumferential direction about a predetermined axis, and configured to hold a work piece, and a driving portion configured to move the three or more holding portions toward a closing direction for approaching the axis and toward an opening direction for moving away from the axis, wherein at least one of the holding portions is swingable, about the axis, at a position at which the at least one holding portion is in contact with the work piece.

A gripping device has at least one tendon associated with a gripping arm and guided in a freely slidable manner along a first and second arm portion thereof through a succession of guiding elements. The guiding elements associated with a first proximal arm portion of the arms are carried by an inner yielding panel so that when the inner yielding panel on the inner side of the first proximal arm portion engages against an item or component to be gripped, the guiding elements of the tendon carried by the inner yielding panel cause a tensioning of the tendon, which results in an articulation and/or inflection movement of a second distal arm portion with respect to the first proximal arm portion.

Provided is a robot hand including: a plurality of claw members configured to grip a gripping target member; a support member that holds one end portions of the respective claw members such that the claw members are swingable; an actuator configured to drive the claw members; and a plurality of sensors attached to the respective claw members, each of the sensors being configured to sense an amount of deformation of a corresponding one of the claw members to which the sensors are attached, when the claw members grip the gripping target member.

A finger for a robotic gripper may include a flexible backbone, a plurality of jamming layers, and a membrane bag. The backbone may have a first side, a second side, a third side, and a fourth side. The backbone may include a flexible beam, and a plurality of branches attached to the flexible beam and spaced apart from one another. Each branch may include a first end surface extending along the first side, and a second end surface extending along the second side. The first end surfaces may collectively extend along a majority of the first side, and the second end surfaces may collectively extend along a majority of the second side. The jamming layers may be positioned along the third side or the fourth side. The membrane bag may be positioned over the jamming layers.

A robot multi-degree-of-freedom clamper has a short stroke biaxial cylinder installed on the clamping jaw supporting frame and an output end connected with a pneumatic clamping jaw A. In addition, a clamping jaw finger A is connected with an output end of the pneumatic clamping jaw A. A long stroke biaxial cylinder is connected with a pneumatic clamping jaw B. A clamping jaw finger B is connected with the output end of the pneumatic clamping jaw B. A pneumatic clamping jaw C is positioned between the pneumatic clamping jaw A and the pneumatic clamping jaw B. A clamping jaw finger C is connected with the output end of the pneumatic clamping jaw C. The clamping jaw finger A and the pneumatic clamping jaw A are driven by the short stroke biaxial cylinder to move back and forth on the clamping jaw supporting frame.

A hand mechanism grips an object more favorably, regardless of the attitude and surrounding conditions of the object. When an object is to be gripped by a hand mechanism having three or more finger portions, at least one finger portion among the three or more finger portions functions as a state-altering finger portion for altering the attitude or the position of the object while contacting the object, and at least two finger portions among the finger portions other than the finger portion functioning as the state-altering finger portion function as gripping finger portions for gripping the object in a state where the attitude or the position has been altered by the state-altering finger portion.
