Background Robotics are increasingly being used in a number of fields, such as industrial manufacturing, warehouse logistics, emergency rescue, and even home services. As a core driving part of the robot, the performance, reliability and service life of a joint motor (usually a servo motor) directly determine the working performance of the whole robot. Therefore, before the motor is installed, the motor is fully simulated and tested, and the key link for ensuring the quality and stability of the robot is realized.
