To calibrate a robot, we first need to understand the factors that may cause the robot to appear wrong.
There are many factors that form robot errors, which can be summarized into two main categories, one is kinematics, mainly processing errors, mechanical tolerance/assembly errors, zero point errors, reducer return errors, 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 entire system of the robot. Once calibrated, the error range of the robot can be greatly 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 main reason for the low accuracy of the robot is that the planning parameters of the robot are different from its actual 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 development process of robots, 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.
