Abstract
In this paper, we would like to report the advanced structure of electric-powered wheel that can go upstairs or downstairs. One of the reasons of electric wheelchair accidents that occur recently is the rollover accident from wheel jamming at a step or stairs. Commercially available electric-powered wheels have a serious problem with malfunctioning of electric wheels. When the gap or step difference is larger than 5 cm, the electric wheel is not working properly. We have intensively investigated this matter by using a variable track wheel method rather than the conventional triangular wheel method that had been studied mostly in the past. We have engineered a prototype electric wheel with a variable track wheel which is tested at various conditions. Our result shows that the performance of the electric-powered wheel with variable track wheel is stable for both of flatland and stairs due to the contracting action of actuator.
