In the aging society, the demand of the movement assisting devices for the elderly gradually increases. As one of these devices, an electric wheelchair is used. An electric wheelchair has two passive casters and two driving wheels. By the attachment position of the driving wheel related to the wheelchair frame, electric wheelchairs are divided into two types of drive systems such as front-wheel drive and rear-wheel drive. Each electric wheelchair has advantages and disadvantages about the operability and maneuverability. Especially, in the front-wheel drive, the wheelchair frame is moved in right and left direction in spite of commanding the straight motion. In this paper, we validate the cause that a front-wheel drive sways in right and left. Therefore, we built a simulation model and compared it with experimental results.
