In the era of rapid development of automation and intelligentization, multi-joint robots, with their excellent flexibility and versatility, are becoming a key driving force for transformation in various industries. They can simulate the complex movements of the human arm and accurately perform various tasks in three-dimensional space, greatly improving production efficiency and operation precision. This article will deeply explore the working principles, wide-ranging applications, core advantages and challenges, as well as future development trends of multi-joint robots.

 

The core of multi-joint robots lies in their flexible structure composed of multiple independent rotating joints. Each joint is usually driven by a high-precision motor, and by precisely controlling the rotation angle and speed of each joint, the robot can achieve complex motion trajectories in three-dimensional space.

 

Joint modules are the key components for multi-joint robots to realize motion, and their design directly affects the robot's performance. These modules are responsible for efficiently converting the energy of the motor into the required physical motion, which can be either rotational or linear. In pursuit of ease of use and energy conversion efficiency, the design of joint modules often embodies the wisdom of precision engineering, ensuring that the robot is both flexible and efficient when performing tasks.
