According to an aspect of the disclosure, a robot arm gripper device includes a grip unit capable of gripping an object by a hinge movement, a power transmission unit coupled to the grip unit and transmitting power to the grip unit, and a buffer unit having one side connected to the power transmission unit and another side connected to a robot arm body, wherein the power transmission unit is movable on the buffer unit.

A transfer system in the form of a robot line used in one embodiment to transfer products, such as slices of meat or other fresh food, while complying with the hygienic requirements. The robot line may transfer the products, simply and with little constructive and financial effort. The robots used for this purpose may be very simply constructed with only one swivel arm and the robot base may be guided below the working plane, and only the swivel arm and the gripper may be disposed above the working plane.

Techniques for a conformal gripping end effector such as a gripping finger are provided. In an example, a conformal finger mechanism can include a proximal link, a connecting link, a distal link, a finger link coupling and a spring. The proximal link can be coupled via a proximal link pivot to an actuator housing and the connecting link can be coupled to an actuator rod of the actuator and the distal link. The distal link can be coupled to the connecting link and the proximal link. The spring can be coupled to an offset portion of a proximal end of the proximal link.

A method is for controlling an actuation force exerted by an actuating device having a first working chamber and a second working chamber supplied with pressurized air from a source of pressurized air by a first pressure regulator and a second pressure regulator. The method includes calculating, by an optimization algorithm based on a dynamic model of the actuating device and of the first and second pressure regulators, desired values for control signals for the first and second pressure regulators to generate an actuation force equal to a desired value for the actuation force. An estimated value for the actuation force, estimated values for pressures inside the first and second working chambers and for first derivatives of the pressures, are determined by a state observer based on a measured value for the actuation force and on measured values for the pressures in the first and second working chambers.

In one embodiment, a robotic end effector configured to mount to a robotic manipulator includes gripping elements configured to grasp objects, a drive mechanism configured to open and close the gripping elements, a central controller configured to control operation of the drive mechanism and the gripper elements, the central controller hosting a control program that enables control of the end effector independent of the robotic manipulator, and at least one of a forward-facing ultrasonic distance sensor configured to measure a distance between the gripping elements and an object to be grasped, and a forward-facing camera mounted between the gripping elements configured to capture video data of an object to be grasped.

A slim and long multifunctional gripping mechanism has a bending- and torsion-resistant structure, on which several finger, suction, magnetic head and other mechanisms for a multitude of tasks are arranged. The gripper arm is composed in sandwich configuration of several cages placed on top of each other, like a multi-stage tower. The individual cages consist of two plates in parallel in lightweight construction, with their mutual distance being ensured by several rods, spokes, wires, ropes and strings. Most of the drives are contained within the first cage after the flange. From that position, all mechanisms participating in the action of the gripper are driven by rods, shafts, ropes, chains or belts traversing the cages. Further cages are used to attach and accommodate the components of finger mechanisms. Movable cages are used as drives for finger, suction or magnetic head mechanisms. Several finger mechanisms perform a different task each.

The automated gripping tool enables a user to move a food product from a first position to a second position while maintaining the integrity and appearance of the food product. The automated gripping tool makes use of flexible gripping elements on the ends of banks of opposing pairs of gripping arms. The flexible gripping elements are positioned to cradle a stacked food product between them with sufficient force to allow the food product to be repositioned and without damaging the integrity of the food product.

The present invention relates to a gripper assembly for gripping a product. The assembly comprises first and second mounting members; an actuator for causing relative movement between the first and second mounting members; and a plurality of gripper members spaced apart about a primary axis. At least one the gripper members comprise a resiliently deformable body comprising a distal end and first and second connection formations spaced from the distal end and from each other, the first and second connection formations being connected to the first and second mounting members respectively such that an axial component of movement between the first and second mounting members caused by the actuator in use imparts a rotation of the distal end of each gripper member in a direction towards and/or away from the primary axis.

An attachment module constructed to enable a vehicle charging robot to attach to a vehicle and to thereafter insert its charging connector into the vehicle's charging socket. Once the vehicle is charged and the charging connector is disconnected from the charging socket, the attachment module is further constructed to enable the robot to detach from the vehicle.

A finger assembly of a robot hand includes a main frame, a tip portion rotatably connected to the main frame, and a band portion connected to the tip portion.
