Abstract
A wheel-type personal mobility robot is expected as a personal transportation machine near the future. In this paper, a new transportation system combined with a personal mobility robot and a train transportation is proposed. The personal mobility robot supplements a weak point of the train transportation, that is, lack of door-to-door movement. Some wheel-type personal mobility machines have been developed. While the Segway is one example of the practical use machines, those machines can not have high mobility on discontinuous rough terrain like a step. In this paper, a personal mobility robot that can move on discontinuous rough terrain is also introduced.
