摘要

A screw tightening robot with AC servo motors, without any torque sensor was developed for a variety of screws. In order to detect the accurate tightening torque, we developed a new torque estimation method by measuring the electrical current of the motor and calculating in real time. The screw-driving process is controlled for the 4th joint's motion of the robot. Thus, this robot tightens screws accurately and reliably without extra cost.
