Abstract
The paper introduces a novel auto-leveling system applied to the obstacle-surmounting robot with six wheellegs. The leveling model of the robot with six wheel legs and one articulated steering is analyzed. Besides, the kinematic model of the robot is presented. In order to optimize the leveling algorithm, a special PID control strategy with the leveling matrix is applied to the leveling system. The experiment shows that the new leveling system can improve the efficiency and the stability of the leveling performance: the leveling time is reduced by 3.5 seconds and the obvious tilt fluctuations are decreased by 5 times.
Keywords: Efficiency, kinematic equations, leveling system, wheel-legged robot.
