Robotic fingers and manipulators

Abstract

The invention provides a mechanical finger and a manipulator. The mechanical finger at least comprises a first knuckle, a second knuckle and a third knuckle, the second knuckle and the third knuckle are fixedly connected with the first knuckle, the second knuckle bends and extends based on a first linkage component connected with the third knuckle, the third knuckle is lifted up and pressed down based on a second linkage component connected with a palm, the third knuckle and the second knuckle bend and extend based on a third linkage component of the third knuckle and a fourth linkage component connected with the palm, a motor respectively connected with the first linkage component, the second linkage component, the third linkage component and the fourth linkage component is arranged in the palm, and four mechanical fingers, one mechanical thumb and the palm can form the manipulator. The mechanical finger has the advantages that the mechanical finger is simple in structure, flexible and low in material requirement and cost, a finger portion is not provided with a power motor and the like.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a mechanical finger and a mechanical hand. Background technique [0002] With the continuous development of science and technology, the concepts of mechanization and automation continue to penetrate into people's production and life. As a common equipment, manipulators have completed a lot of repetitive work on the factory assembly line. [0003] As the imitation of human beings to their own hands, the bionic manipulator has extremely high flexibility in many manipulators with different structures. However, due to the wonderful results of biological evolution, the bionic manipulator is far from reaching the level of "ingenuity". Numerous joints, joint power miniaturization, joint coordination and other problems limit the hand flexibility of the machine. [0004] In the development of manipulators, some use advanced small motors, which solve the problem of joint dexterity, but increase the...

Problems solved by technology

like Figure 1a and Figure 1b As shown, a slender finger includes: first phalanx 11, second phalanx 12, third phalanx 13, first joint 14, second joint 15, third joint 16, visible, slender finger And a large number of joints make the human hand have unparalleled flexibility, and it is precisely because of the slender structure of the fingers that it is difficult to place joint dynamics in the fingers; at the same time, it is difficult for the control system of a large number of joints to reach the human brain. inadvertent control effects

If advanced technology is used, of course better results can be achieved, but it will also greatly increase the cost of manipulators.

Therefore, due to various reasons, the current low-cost bionic manipulators are still difficult to achieve the flexibility of human hands.
