In this paper, the way of extended Kalman filters combined with registration algorithm is proposed to improve position precision of the robot, the problems such as the low precision of terminal trajectory and the inaccurate analysis of control compensation have been solved. First, the mathematical model of SCARA robot and error analysis evaluation model are established. Based on extended Kalman filters and registration algorithm, the terminal trajectory precision has been improved. As result, through simulation by professional software, analyzing the difference of using algorithm and not using algorithm, the reliability and accuracy of the algorithm is proved
