Abstract

The essence of mobility in humans cannot be over-emphasized, thus the difficulty that persons living with motor impairment suffer with impeding effect on their physical development and social interactions. Electronic driven wheelchair (EDW) can mitigate against the effects of the aforementioned suffering. However, the cost of acquiring an EDW is beyond the reach of an average Nigerian. In this paper, the design and fabrication of a locally produced low cost EDW was reported. The device was designed for outdoor use with two rear motor driven wheels, two 12V DC deep cycle batteries, angle bar, galvanized metal pipes, solar panel, rattan (cane) and bamboo. Control for the EDW is achieved through the use of a joystick. The batteries can be charged either by using 220V AC mains or a solar module. The framework of the wheelchair is made up of about 50% metal, 35% rattan, and 15% bamboo. Available anthropometric data for Nigerian adult was used in designing an applicable prototype. The product of the study is a functional EDW. The essence of the innovation is to afford average income earners the opportunity to acquire and use an electric wheelchair.
