Abstract
Escalator is an effective mass transportation method. But ordinal wheel chair cannot use escalator because of its instability on the uneven height steps. If the stability is obtained by changing its configuration, the wheel chair can move by an escalator simultaneously together with other pedestrian. This paper describes about the feasibility study of the escalator travel by the variably configured wheel chair, which changes its configuration by means of parallel link mechanism. The experimental result shows that the stability on the escalator can be kept and the escalator travel using the proposed wheel chair is possible.
