Abstract

The invention provides a dexterous hand which comprises a thumb structure and a plurality of four-finger structures, wherein the thumb structure comprises a first linear steering engine, a first transmission piece connected to the first linear steering engine, a second linear steering engine, a second transmission piece connected to the second linear steering engine, and a thumb shell; the first transmission piece and the second transmission piece are both connected to the thumb shell; an included angle is formed between the movement directions of steering engine push rods of the first linearsteering engine and the second linear steering engine; and each four-finger structure comprises a four-finger linear steering engine, a third transmission piece connected to the four-finger linear steering engine, and a four-finger shell driven by the third transmission piece. According to the dexterous hand, through cooperation of the first linear steering engine and the second linear steering engine, movement of the thumb shell in all directions can be achieved, and the thumb shell is made to be more similar to the thumb of a human being to move.

Description

technical field [0001] The invention belongs to the technical field of robots, and more specifically relates to a dexterous hand. Background technique [0002] There are many types of robots, such as humanoid robots, industrial robots, and service robots. Humanoid robots have a high degree of similarity to human actions. Therefore, the movements of the hands of humanoid robots are relatively fine and can achieve a variety of actions, thus the emergence of dexterous hands. The finger movement of the dexterous hand imitates the movement of human fingers, but the finger movement of the current dexterous hand is simple, the movements that can be realized are few, and the imitation of human is poor. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a dexterous hand to solve the technical problems in the prior art that the movements of the fingers are simple and the movements that can be realized are few. [0004] In order...
