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.

The prosthesis or orthosis comprising a moveable component, a motor operable to move the component, wherein the motor has at least one operating parameter, the application of which to the motor results in the component having at least one operating condition; and an electronic device operable to: determine at least one operating parameter of the motor and determine at least one instantaneous operating condition of the component from a predetermined operating profile of the motor and component and the determined at least one operating parameter of the motor, the predetermined operating profile of the motor and component being based on one or more operating parameter inputs to the motor and one or more resulting operating condition outputs of the component.

A finger-detachable dexterous hand includes a palm (10) and a plurality of fingers (20), wherein the palm (10) is provided with a plurality of finger mounting slots (101) for the fingers (20) to be inserted and mounted therein; and the dexterous hand further includes: locking assemblies (102) mounted in each of the finger mounting slots (101), and locking blocks (201) arranged at an inserting end of each of the fingers (20), wherein the locking assemblies (102) and the locking blocks (201) are connectible and lockable to each other for attaching and detaching the finger (20) to and from the finger mounting slot (101).

A system and method for a prosthetic assembly that includes a first prosthetic component, comprising a prosthetic hand base; a set of second prosthetic components, comprising a set of prosthetic fingers, and a set of actuating systems, wherein one actuating system connects a pair of distinct prosthetic components, enabling actuation of one prosthetic component with respect to the other. Each actuating system, from the set of actuating systems, includes a linkage and a sensored brushless motor; wherein the sensored brushless motor comprises a brushless motor, a field oriented control system, a rotary encoder, and a gearbox.

Provided is a joint structure for a robot which can prevent leakage of a lubricant which is charged to the interior of the joint structure while improving a drip-proof property. The joint structure for the robot includes: a first arm which is hollow; a second arm which is rotatably mounted to the first arm; a power transmission mechanism which is provided adjacent to the outside of the first arm, the power transmission mechanism including a gear and an inner space which houses the gear and is charged with a lubricant; a booster section which increases a pressure in an interior of the first arm to be higher than an outside pressure; and a one-way communication section which allows the interior of the first arm and the inner space to communicate with each other and a gas in the interior of the first arm to flow into the inner space, while preventing the lubricant in the inner space from flowing out to the interior of the first arm.

In a finger mechanism and a robot hand having the finger mechanism, the finger mechanism uses a link based mechanism, and performs three degrees of freedom including two degrees of freedom of MCP joint and one degree of freedom of PIP join, via a driving part disposed at a side. The driving part is not disposed at each knuckle of the finger mechanism and additional sensors may be easily equipped, and thus modularized robot hand may be performed using the finger mechanism.

An electric motor has a first carrier having an array of electromagnetic elements and a second carrier having electromagnetic elements defining magnetic poles. The first and second carriers each define an axis. An airgap is formed between the first and second carriers when in an operational position. An inner thrust bearing connects the first and second carriers and is arranged to allow relative rotary motion of the carriers. An outer thrust bearing connects the first and second carriers and is arranged to allow relative rotary motion of the carriers. The electromagnetic elements of each of the first and second carriers are arranged radially inward of the outer thrust bearing and radially outward of the inner thrust bearing. The inner thrust bearing and the outer thrust bearing are arranged to maintain the airgap against a magnetic attraction of the electromagnetic elements of the first and second carriers.

Disclosed is a gripper for robot hand capable of adaptive grasp, including a finger unit having one or more finger which includes a first link of which one end is rotatably fixed to a casing; a second link of which one end is jointly coupled with the other end of the first link; a third link of which one end is rotatably fixed to the casing, which is operated by receiving a driving force from the outside; a fourth link of which one end is jointly coupled with the other end of the third link; and a gripping member jointly coupled with the other end of the second link and the other end of the fourth link.

A humanoid robot capable of identifying an individual in a natural way is described. This humanoid robot shakes a hand of a person to acquire biological information of the person and identify the individual person. Particularly, a near infrared light emitting device and a near infrared sensor are installed in a hand of the humanoid robot to irradiate a hand of a human being with near infrared light emitted from the near infrared light emitting device and detect a vein pattern by the near infrared sensor. The individual person can be identified by recording and collating this vein pattern.
