A NEW WHEELED AUTONOMOUS MOBILE WELDING ROBOT SYSTEM BASED ON ROTATING ARC SENSOR

A new wheeled mobile welding robot based on rotating arc sensor is presented. The front wheels are used to veer and are controlled by step motor, and the near wheels are used to drive and are controlled by AC servo motor. The cross-slider is controlled by DC servo motor. These four motors are controlled by a four axis motion controller. The integration grade and control efficiency are improved greatly, and at the present time it is a new automatic welding equipment.
