Recently, simplified electric wheelchairs, that is, wheelchair with a motorized device attached to a manual wheelchair has been gathered attention. Simplified electric wheelchairs are relatively lightweight and can be folded. However, simplified electric wheelchairs have a risk that the wheelchair will fall backward when running over a step. To solve this problem, we developed the 3-wheeled simple electric wheelchair. This wheelchair has two large wheels and an active-caster, a type of powered caster which can move in any directions. With this structure, the active-caster saves as a support, the risk of falling backwards can be reduced when the wheelchair running over steps. However, 3-wheeled simple electric wheelchair have a problem that stability of straight running is poor. In this paper, we will clarify that deflection of 3-wheeled wheelchair traveling direction is caused by human control by experiment. Also, confirm the improvement of running stability by the angular velocity feedback.
