Diseño e implementación de un sistema de control electrónico de una silla de ruedas eléctrica con ubicación GPS y mando local o remoto a través de una aplicación celular android, para personas con discapacidad motriz reducida en miembros inferiores.

Abstract

This degree work is focused on designing and implementing an electronic controller based on Arduino for an electric wheelchair (Modified conventional wheelchair), with two modes of operation Local control, through an integrated master controller that allows control of the chair through a joystick and a series of components with different functions, such as, speed controller, remote control, panic button, horn and automatic table. - Remote control, through a cellphone with bluetooth communication and an application that contains a joystick and speed regulator, that allows to control the movements and speed of the chair. The integration of a GSM / GPS module allows the controller to receive / send text messages and request geographical position coordinates. For the implementation of the project several designs of printed circuits board were made to integrate the different systems previously proposed. Motion and speed control algorithms were designed to control the wheelchair locally and remotely. The design of a multifunctional application for Android phones, allows the chair’s user and a legal guardian to have several options: Remote control, explained previously. Location, allows the user’s guardian to receive and visualize the geographical coordinates of the wheelchair at the requested time. Security: Allows security locks of the functions of the wheelchair with or without coordinate reports, in case of theft, emergencies or fortuitous events. Functionality tests were performed, with different individuals, and satisfactory results were obtained that allow the beneficiary, Robert Hidalgo, to use the electric wheelchair with an autonomy of 14 hours and an approximate performance of 25 kilometers, satisfying his needs for mobilization and those of his mother, giving her the security of knowing where her son is, when he is away from home.
