Development of Electromagnetic Unmanned Robot Applied to Automotive Test

Abstract:

A novel electromagnetic unmanned robot applied to automotive test (URAT) based on the conversion principle of electric-magnetic-force is proposed. Electromagnetic URAT adopts electromagnetic linear motor (EMLM) as its drive mechanism. The mechanical system structure and the control system structure of electromagnetic URAT are designed. The coordinated control method of multiple manipulators is given. Experiments are performed using a Ford FOCUS car. Experimental results shows that electromagnetic URAT can smoothly achieve starting, acceleration, shifting, steady speed and deceleration. The overshoot of speed tracking control during transition from the acceleration stage to steady stage is small. Moreover, the speed fluctuation at the steady stage is smooth, and the speed control accuracy can meet the requirements of national test standards. The robot can automatically drive different vehicle models instead of human driver without need of any automobile modification.
