Abstract
When a wheelchair is driven on a waving ship, the operation becomes very hard, and it is highly dangerous. In this study, we consider the operation of a wheelchair that has a small side-rolling motion. Then we have developed several types of assistance devices for a waving condition. In this paper, we show the special wheelchair with the assistance device, which has a limited slip differential gear mechanism. It is expected to get a safety and comfortable operation at the waving condition
