Research on calibration method of base coordinate system for Dual robots

Aiming at the complex calibration process and low positioning accuracy of the base coordinate system of double robots, this paper proposes an improved base coordinate system calibration method of double robots based on "three-point circle determination".By analyzing the error principle and introducing Gaussian white noise error, the experiment is designed by combining theoretical analysis and software simulation.The results show that the improved calibration method has accuracy and stability, and maintains good positioning accuracy.
