Robot bionic finger

Abstract

The invention relates to a robot bionic finger, comprising a palm component that is connected with four common finger components and a thumb component. The thumb component comprises a thumb tail joint, a thumb middle joint and a thumb tip joint which are connected in sequence; an independent swing mechanism is arranged in each of the three thumb joints for the purpose of driving; the three swing mechanisms can drive the three thumb joints to bend and wing to the longitudinal axis of the palm; the thumb tip joint is connected with a second rotating mechanism that may drive the whole thumb component to rotate along the transverse axis of the palm; the second rotating mechanism is connected with a first rotating mechanism that may drive the whole thumb component to rotate along the longitudinal axis of the palm. The robot bionic finger has high flexibility; the thumb component has five degrees of freedom and is available for independent control; the thumb component can cooperate with other finger components to arrive at the moves, such as opening and closing of the part of the hand between the thumb and the index finger, flexible nipping of each finger, fist making, palm standing, andgrabbing.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a robot bionic finger. Background technique [0002] In recent years, the application of robot technology in both industrial and civil fields has developed rapidly. The manipulator is the final actuator of the robot's work, and its performance directly determines the working ability of the robot. Similar to humans, the development of manipulators with high versatility and dexterity is necessary. [0003] Most of the existing robot fingers use cable control to control the activities of each joint, and the degrees of freedom of each finger are relatively limited. For example, the Chinese patent (publication number: CN104942818A) applied by Tsinghua University discloses a five-fingered manipulator with 7 degrees of freedom. , the thumb is composed of two knuckles, has a bending degree of freedom and a swinging degree of freedom, the degree of freedom of each finger is mainly achiev...

AI Technical Summary

Problems solved by technology

[0004] This application provides a robot bionic finger, which solves the problem that the cable-controlled control method of the bionic hand in the prior art makes each finger implicated in movement, and each finger, especially the thumb, has less degrees of freedom, and cannot independently rotate and cooperate with each other at multiple angles, and can only complete a very small amount. Simple movements, technical problems that most bionic movements cannot complete
