Electric wheelchairs have been widely used by the elderly and care recipients. Since the wheelchairs require hand-operation, drivers cannot deal other tasks requiring their hands. It is preferable driver's hands is free for safety. Additionally it can get over a low level difference smoothly. In this study, an inverted pendulum type wheelchair is developed that enables turning based on sensing air pressure of the cushion, and back and forth movements by the motion of the driver without the hand-operation. Back and forth movements and rotational control systems for the wheelchair are designed using a disturbance observer.
