To calibrate a robot, we first need to understand the factors that may cause the robot to go wrong.
There are many factors that form errors in robots, and there are two main categories, one is kinematics, mainly processing errors, mechanical service/installation errors, zero-point errors, reducer returns, reduction ratio errors, calibration errors, etc.; The second is kinematics, mainly mass/center of gravity, inertia tensor, friction, joint flexibility, connecting rod flexibility, etc.
In practice, it is found that there are generally 15-30mm errors in the base of the robot without calibration, 5-10mm errors in the center end of TCP, and 5-10mm errors in the whole system of the robot. Once calibrated, the size of the robot's errors can be significantly reduced.
· If the robot is not calibrated, the robot cannot share the program, the accuracy is very low and unstable;
· calibration can improve the robot's ability to deal with environmental uncertainty;
· The primary reason for the low accuracy of the robot is that the design parameters of the robot are different from its practical parameters, and the robot calibration is a measure to improve the accuracy of the robot, which can often improve the accuracy by several orders of magnitude;
· In the process of robot development, it is necessary to obtain enough accurate data to analyze and evaluate the static and dynamic of the machine, and these data rely on a complete calibration system to obtain.

Characteristics of industrial robot joint transmission chain - Denso robot
The drive source of the industrial robot drives the movement or rotation of the joints through the transmission parts, and then completes the movement of the body, arms and wrists. Therefore, transmission parts are important components of industrial robots. According to different transmission types, transmission components can be divided into linear transmission organization and rotary transmission group.

Misunderstanding of industrial robots - Denso robots
Myth 1: Only recognize the brand, brand first. The correct concept is that when buying a robot, the brand can be used as a reference, but it can't be too sure. It is mainly considered by looking at the composition of the central elements, the degree of design optimization with its own use, and the degree of consistency between the intention and function of use.
