Electric wheelchair module: Converting a mechanical to an electric wheelchair

There is a growing need for transportation, either inside a house or office, as well as in the streets and other public spaces. This constant need is a disadvantage for anyone with some kind of disability, specially those that suffer motor disabilities. Electric wheelchairs are part of the technological solutions to this demand. However, their cost are very high in constrast to mechanical wheelchairs. In that sense, this paper aims to present a new module device that can be used for converting a mechanical wheelchair to an electrical one. The proposed device was designed for simplicity in installation, high benefit-cost ratio and easiness in control movement. Preliminary results showed the implementation of the proposal in a functional prototype.
