Desenvolvimento de um sistema de controle para cadeiras de rodas automatizada baseado em movimentos da cabeça

Abstract

In the world cenario there is half billion of people with some kind of disability. In Brasil, there are around 45 millions of people with disabilities and, among them, 65,9% earn monthly up to the minimum wage, wich indicates that this population is mainly composed by poor individuals and, however, motorized wheelchairs and other acessibility equipments have a market price that is not affordable for this part of population. In this perspective, this work develops a low cost helmet that reads the user head movements and triggers the adapted wheelchair for individuals with tetraplegia. Then, was used low cost components in the project as Arduino R, IMU, among others. Simulations were made to evaluate the system in virtual system and a mobile robot that intends determine environment limitations, filtering and achieve an economical and funcional prototype. Furthermore, concerned with engineering education, was developed a tutorial for this prototype development by engineering students or engaged people in this area, working in benefit of education and improving the project constantly.
