Actualization of safe and stable stair climbing and three-dimensional locomotion for wheelchair

Abstract

Leg-wheel hybrid mobile vehicle has been regarded as the best combination and many of them have been presented recently because of the high terrain adaptability of legged walking robots on rough ground and the high mobility of wheeled mobile vehicles on flat terrain. We discuss the detailed actualization of safe and stable stair climbing and three-dimensional locomotion for wheelchair - with mainly indoor or ordered terrain environments - in mechanism sensor system and control method based on the developed leg-wheel hybrid mobile vehicle Zero Carrier I in this paper.
