Joint robot motor manufacturer reveals: basic principles of joint robots。
In this era of rapid technological development, robots should be familiar to everyone. For robots, joints play an important role in connecting and driving various components, and their design and performance directly affect the robot's mobility and work efficiency. Today, let's learn about the basic principles of articulated robots.
1. Control section
The control system of a robot is a computer that not only controls the motion of various degrees of freedom, but also is responsible for many other things, one of the main issues being how to ensure safety. For the drive of each axis, a separate servo system is set up, which consists of a three ring system. The control system of the robot also includes a servo system, with several degrees of freedom corresponding to several servo systems. Currently, the most common type is the electrical servo system. In some special occasions, hydraulic and pneumatic servo systems are also used.
2. Execution section
So far, the mechanical structure of robots has only achieved certain functions of human arms and hands, and these arms of robots are motion chains composed of interconnected components and motion pairs. The connecting rod (component) can be called an arm, the motion pair is called a joint, and the joint can be divided into translational joint and rotational joint. The end of the robot is called the wrist. In robots, the arm determines the position that the robot can reach, while the wrist determines the robot's posture. To complete specific tasks, robots not only need to reach the designated position, but also must make the required posture at that position.
