Problems solved by technology

[0003] At present, the arms of small humanoid robots generally use steering gear as the joint drive component. Since the structure and size of the general steering gear have been finalized, the connecting parts and shell of the robot arm can only be designed according to it.
However, the motor shaft of the general-purpose steering gear and the output shaft of the reduction group are not in the same axis, which makes the design of the connecting parts of the robot arm complicated, and the structure of the arm is difficult to modularize and miniaturize

Abstract

The invention relates to the technical field of robots, in particular to a multi-joint robot arm. The multi-joint robot arm comprises a shoulder rotary joint, a big arm swing joint, a big arm rotary joint, a forearm swing joint, a forearm rotary joint and a wrist swing joint. The device provides a modularized mechanical joint and the robot arm using the modularized mechanical joint, the design ofthe robot arm can be more simplified, and the installation space is effectively reduced. The shoulder rotary joint is welded with the big arm swing joint, the big arm swing joint is connected with thebig arm rotary joint through a bolt, the big arm rotary joint is welded with the forearm swing joint, the forearm swing joint is connected with the forearm rotary joint through a bolt, and the forearm rotary joint is welded with the wrist swing joint.

Description

technical field [0001] The invention relates to the technical field of robots, and more specifically relates to a multi-joint robot arm. Background technique [0002] A multi-joint robotic arm can imitate the movement of a human arm, and the more joints there are, the more realistic the imitation of human arm movements will be. To accurately imitate the movement of the human arm, the arm of the robot usually needs to have: the upper arm swing joint, the upper arm swing joint, the upper arm rotation joint, the lower arm swing joint, the lower arm rotation joint, and the wrist swing joint. [0003] At present, the arms of small humanoid robots generally use steering gear as the joint drive component. Since the structure and size of the general steering gear have been finalized, the connecting parts and shell of the robot arm can only be designed according to it. However, the motor shaft of the general-purpose steering gear and the output shaft of the reduction group are not i...
