A gripping device having a holder and two gripper units. Each of the gripper units has a base body and two base jaws. The base jaws can be moved synchronously in opposite directions relative to the respective base body. The gripper units are arranged side by side on the holder so that the base jaws of both gripper units can be moved parallel to a common gripper plane. The gripping device is designed as a single gripper in that only a first gripper finger is attached to each of the two outer base jaws. It can very easily be converted to a double gripper by attaching two further gripper fingers to the inner base jaws, or by removing the first gripper fingers and attaching a second gripper finger to each of the four base jaws.

A robot hand includes a motor with a rotary shaft, an accommodating member accommodating a distal end of the rotary shaft, a plurality of swing members swinging with respect to the accommodating member due to rotation of the rotary shaft, and a plurality of claw members swinging with the plurality of swing members.

Provided is an apparatus for piston insertion, including an insertion robot having a plurality of robot arms connected by a plurality of articulated joints, a piston insertion module directly mounted on the insertion robot, gripping a piston assembly, and inserting the piston assembly into a cylinder bore of a cylinder block, and a controller controlling an operation of the insertion robot and an operation of the piston insertion module.

A gripper for capping machines intended for screwing a cap onto a container adapted to being capped, in particular has a threaded neck for being capped. The gripper has a body capable of revolving on the axis of rotation, and at least two levers adapted to taking at least two different positions. The first position in which it is possible to insert a cap between the gripper levers and the second position in which the cap is locked between the gripper levers at least rotationally. At least one moving guiding shackle hinge-is mounted to the body and at least one lever which is slidingly mounted to the gripper body by means of a guide enabling movement of the lever in a horizontal direction, perpendicular to the axis of the gripper, and the end of the guiding shackle is slidingly and rotatably mounted to the at least one lever.

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 example device includes fingers that are adjustable longitudinally and configured to grip a workpiece. A clamping or locking mechanism can be used to secure the fingers at desired longitudinal positions. In examples, a retaining component is disposed through the fingers and is configured to retain the fingers in lateral directions.

Object manipulation in warehouses and logistics facilities is a challenging task because of the unstructured environment. The unstructured environment can have items/objects with different form factors, weight, shape, and size. Traditionally, multiple robots have been used to handle for specific task to be performed by an individual robot which requires high floor. This leads to higher cost and infrastructure. Embodiments of the present disclosure provide a gripper apparatus that addresses a single gripper design handling multiple parcels, wherein the apparatus consists of ‘m’ fingers parallel to each other and can be independently controlled through actuators, each finger has a force sensors feedback and also actuators which are controlled with force. Each finger comprises a linear slider for actuation for gripping objects and wherein bottom fingers are moved to provide enough gravity support. Further, apparatus comprises bellows attached to each finger end for grasping object using pneumatic grasping mechanism.

An automatic picking fixture device: a fixture locked with a mechanical arm and includes a coupling orifice, a motor, a rotor, and a gear. The fixture includes four elongated orifices and two movable holders. The two movable holders have four through orifices corresponding to the gear, four passing orifices, and two toothed sections received in the four through orifices and meshing with and driving the gear. The four passing orifices of the fixture is configured to lock with the four pneumatic cylinders or four servo motors, and the four pneumatic cylinders or the four servo motors are configured to push four jaws outward or inward, the four jaws include four symmetrical clamping grooves configured to clamp at least one material. The four racks are fixed on the top of the fixture, and a respective rack has two rollers rolling along a respective elongated orifice.

A workpiece holding apparatus includes: a main body; at least one shaft member capable of coming into contact with a workpiece; a clamping device into which the shaft member is inserted, the clamping device being attached to the main body and capable of switching between an unclamping state that releases the shaft member and a clamping state that clamps the shaft member; and a trigger member configured to switch the clamping device between the unclamping state and the clamping state. The trigger member comes into direct contact with the workpiece, or comes into indirect contact with the workpiece via at least a part of the shaft member, thus moving relative to the main body, and the clamping device switches from the unclamping state to the clamping state.

A robot control apparatus for controlling a robot manipulating a target object includes a measurement unit configured to measure a change of a gripping unit configured to grip the target object when the gripping unit contacts the target object, a first acquisition unit configured to acquire the change of the gripping unit measured by the measurement unit, a second acquisition unit configured to acquire a gripping state, which is a state of gripping of the target object by the gripping unit, based on the change of the gripping unit acquired by the first acquisition unit, and a control unit configured to control an action of the robot based on the gripping state acquired by the second acquisition unit.
