Controle de movimentação de cadeira de rodas por comandos de voz utilizando Google Assistant

Abstract

Electric wheelchairs are essentials for the movement of handicapped people. Although, most of the electric wheelchairs are joystick controlled, which is hard or even impossible for some handicapped person, depending on the disability. Many researches have proposed alternatives, though most of them are complex, requires high computational capacity or are expensive. On other hand, Voice User Interfaces popularity has been growing due to the high range of devices that supports the applications and the availability of internet nowadays. Therefore, this undergraduate thesis has developed the control of wheelchair's movement through voice commands using Google Assistant. To represent an electric wheelchair, it was used a robotic chassis controlled by an ESP32 and developed and architecture connecting an action of Google Assistant, a database from Firebase Realtime Database and the ESP32 in order to send voice commands to the robotic chassis. Finally, through the results obtained, it was seen an acceptable performance on the architecture of the system, though the movement control part of the thesis leaves possibilities for future improvements.
