A robot shares a work space with a person, to perform an operation. The robot includes a shock-absorbing member which covers the periphery of at least a base part of a working tool attached to an robot arm, a detector which is provided for the robot arm, to detect an external force input via the shock-absorbing member, and a robot control device which stops the robot when determining, based on information of the detected external force, that the working tool collides with the person. The external force is transmitted from the working tool to the robot arm, and is detected by the detector.

The present invention provides a holding mechanism capable of well preventing misalignment of a workpiece even if the outer diameter of the workpiece is changed when the workpiece is supported at three points by a flat face and a V-shaped groove. Additionally, the present invention provides a holding mechanism of a transfer device capable of stably detecting a chucking error of holding claws for a workpiece.

The invention discloses an embedded system for dexterous hand, comprising: a central communication unit, several fingers, a palm; wherein the central communication unit communicates with the fingers, the palm and a host computer, and is configured to receive an operation instruction from the host computer, and convert the operation instruction into a control instruction and send it to the fingers and the palm; the fingers and the palm are designed to be compatible in hardware structure, and are connected by serial communication; the fingers and the palm move according to the control instructions. The fingers and palm are designed as embedded compatibility standards, which makes the dexterous hand more flexible and easy to maintain and use with lower cost. Thus, the dexterous hand has the advantages of high flexibility, high reliability, strong anti-interference, low cost, high transmission speed, convenient maintenance, and good user experience.

Disclosed herein are implementations that relate to determining tactile information using encoders coupled to one or more fingers of a robotic gripping device. The robotic gripping device may include a finger. The finger may include a deformable front face, a base link, a first encoder, and a second encoder. The first encoder may be coupled to the base link of the finger, and configured to detect a grip angle of the finger while the robotic gripping device is gripping an object. The second encoder may be coupled to the deformable front face of the given finger, proximate to the base link of the finger. Additionally, the second encoder may be configured to detect a bend angle of the deformable front face of the finger while the robotic gripping device is gripping the object.

Disclosed is a compact, lightweight hydraulic manipulation system used for underwater applications consisting of two parts: a modulus hybrid underwater manipulator and a compact lightweight hydraulic control framework. The system is used for general underwater work such as underwater sampling, hyperbaric welding, and marine aquaculture.

A reusable mechanism is disclosed for coupling two robotic appendages, such that an unintended force acting against a side of one of the appendages may decouple the appendages. The mechanism includes a revolved male dovetail mated to a revolved female dovetail. The mechanism may further include a channel within the male dovetail and a detent that inhibits rotation of the male dovetail in relation to the female dovetail.

A gripper for industrial manipulators includes: at least two jaws one of which being movable allowing it to be opened and closed; and a gripper body. A first gripper body portion housing an actuator device and a second portion supporting the jaws and at least one pin element, defining a pivot axis of the movable jaw, or a pivot axis of at least one transmission element operatively interposed between the at least one movable jaw and the actuator device. The gripper arranged so that the pin element also acts as a locking pin to firmly lock together the first and second portions of the gripper body in assembled condition. The pin element having a circumferential groove which allows a snap coupling of the first portion and the second portion of the gripper body: an elastic element separating them and engaging the edge of one of the two in the groove.
