In this work the main objective is the development of systems for the motorization of conventional wheelchairs. Most of the simplest types of wheelchairs now available in Brazil do not allow the pure and simple conversion to motorization. In this aspect, the problem comes as a challenge because the great variety of models and types of wheelchairs and the lack of a rigorous normalization demand the use of technologies so as to search for solutions and apply methodological know how and a systematical approach of project. In this way, first a study will be carried out on the wheelchair, consisting of: history, origin, type and characteristics. The following step will be to search for possibilities of motorizing conventional wheelchairs, their limitations and applications. Eventually, after the definition of a basic type to serve as a model, the systematical approach of the project will be applied for the development of a product and the execution of a prototype in scale or its function for the evaluation of possibilities. In the development of the product, a methodology and system of project will be used. The objective of this work is study the possibilities of motorizing a conventional wheelchair. This article analyses the possibilities of motorization.
