Protótipo de baixo custo de uma unidade de tração para cadeiras de rodas manuais com sistema embarcado

Abstract

The present work aimed to develop a traction unit for manual wheelchairs with an embedded system. With a mechanical device it was possible to attach a traction unit to the wheelchair that made it possible to move and with the help of a mobile application it was possible to signal panic and locate the wheelchair user. Initially, the theoretical basis for the development of this work will be presented: medical and scientific concept of paraplegia, locomotion of an individual with low mobility, study on motors, sensors, energy management, atmega328 microcontroller and bluetooth communication networks. In addition, the location can be sent to a relative or friend and follow the route via the app. Subsequently, the steps and materials necessary for the construction of the traction unit, monitoring, are presented, followed by a detailed description of the experiment, tools used and implementation of what was mentioned. Finally, the data obtained were observed in the autonomy tests with the best result of 37.04 km, with an average speed of 10 km/h. The panic button sent the location via SMS to the contact registered in the application and the satisfaction survey confirmed that the prototype developed meets the proposed requirements when helping the displacement of a person with low mobility in outdoor environments.
