The wheeled-legged robot has excellent stable flat driving and ability to overcome obstacles. However, when faced with a narrow footprint, there is a limit to the ability to move. To solve this problem, we developed a CMG (control moment gyroscope) unicycle robot. A scissored pair of CMG was applied to control the roll direction balance, and the pitch direction balance was controlled assuming that the robot was a double inverted pendulum. In a system where the control systems in the roll direction and the pitch direction were decoupled, LQR and MPC optimal control were performed, and the performance of these controllers was verified as gazebo simulator.
