A rotatable wheeled mobile robot applied in special rough environment, such as climbing slop and turning a somersault was stadied. The climbing capacity and the dynamic modeling of turning state were analyzed. Some factors affecting the maximum angle of climbing slop were obtained. The dynamic modeling of turning states was inferred by Alembert Principle. Some parameters are analyzed combining driving ability. The robot’s condition of overthrow and reset was gained. The designing the wheeled mobile robot, which can run successfully in a complicated environment, and developing its adaptability
