Side swing mechanism, dexterous hand and robot

By employing a lateral swing mechanism with drive components and linkages in the dexterous hand, the problem of structural complexity and large size caused by the need for independent drive of each finger is solved. This enables lateral swing of multiple finger joints, reduces the size and weight of the lateral swing mechanism, and improves the anthropomorphism and biomimicry of the dexterous hand.

AI Technical Summary

Technical Problem

Each finger of a dexterous hand requires a lateral swing mechanism for actuation, resulting in a complex structure and large size, which reduces its anthropomorphism and biomimicry.

Method used

A side-swing mechanism is adopted, including a drive component, a first link and a second link. The side-swing of multiple knuckles is realized through a single drive component, which reduces the complexity and size of the side-swing mechanism.

Benefits of technology

It achieves lateral swing of multiple finger joints, reduces the complexity and size of the lateral swing mechanism, makes the size of the dexterous hand closer to that of a human hand, and improves anthropomorphism and biomimicry.

Abstract

The application relates to the technical field of robots, in particular to a side swing mechanism, a dexterous hand and a robot, which solve the problems that the side swing movement of each finger of the dexterous hand needs a side swing mechanism to drive, leading to the problems of complex structure and large size of the dexterous hand. The side swing mechanism comprises a driving assembly, a first connecting rod and a second connecting rod. The driving assembly is connected with a first phalanx and drives the first phalanx to rotate to realize the side swing of the first phalanx; the first phalanx drives a second phalanx to rotate through the first connecting rod to realize the side swing of the second phalanx; and the first phalanx or the second phalanx drives a third phalanx to rotate through the second connecting rod to realize the side swing of the third phalanx. Therefore, the side swing mechanism realizes the side swing of multiple phalanges through one driving assembly, reduces the complexity of the side swing mechanism, reduces the size of the side swing mechanism, thereby reducing the size of the dexterous hand and making the size of the dexterous hand closer to that of a human hand.
