Abstract: An innovative Antarctic roaming robot is presented based on windsurfing & sled. According to the aerodynamics analysis of the windsurfing and the mechanical analysis of the sled, the mechanical model of Antarctic roaming robot is established, and the principle of locomotivity is analyzed. By the simulation experiments, the basic driving condition, velocity and motion range of robot are determined. Based on the theoretic analysis and simulation calculation, the structure parameters of the robot are optimized, and its principle prototype is designed and manufactured. Finally, the results of theoretic analysis and simulation are validated by the snowfield experiments.
