Sistema eletrônico para motorização de um protótipo de cadeira de rodas convencional.

Abstract

Physical-motor disability is a complete or partial change related to muscle groups and bone structures, compromising people to perform their physical functions. When those affected by the disability are the lower limbs, the individual in some cases is forced to use a wheelchair to move around. The main objective of this work is the development of an electronic circuit aimed at the motorization of a conventional wheelchair prototype. Due to the high cost in relation to motorized wheelchairs, access to the equipment becomes increasingly difficult for the population with low economic power. This project was divided between the construction of a wheelchair model made from PVC tube that will be used as a demonstration and the elaboration of the electronic system responsible for transmitting and controlling signals, which will be coupled to the structure of the chair, which enabled movement. of the prototype with a joystick, it drives the DC motors that constitute the operation. Therefore, the combination of a PVC heelchair structure with an electronic control system allows the user to move the chair in a simplified way using a joystick, providing an option that helps wheelchair users who do not have high purchasing power in their daily commute.
