Abstract

Nowadays, the number or elderly people has increased. Some live with their children, some live in the adult foster home and some even live by themselves. The problem arises when the elderly people lose their ability to walk. Not everyone can be present to help them at all time. This project is built to help those who have trouble using their feet to walk around due to some difficulties such as helpless elderly people or people who met with accidents and end up with paralyzed legs. The aim of this project is to develop Wireless Android-Based Wheelchair Control and System that consists of an android device and a control box that controls the movement of wheelchair by using DC motor. The source code is written in (Basic-4- Android) software. IOIO is the main controller that controls motor, sends signal to RF receiver and receives serial data from android phone. Bluetooth communication protocol is used for communicating between the android device and the control box. The motor direction and speed are controlled by motor driver MD30C through IOIO. Three control interfaces which are D-pad, joystick and voice are used to control for the wheelchair movement. The four conditions can be described as forward, backward, right and left. This system also has the ability to control electrical appliances by using radio frequency as the wireless communication. Electrical appliances can be switched on and off wireless by using radio frequency transmitter to send a signal to radio frequency receiver. As a conclusion, this product not only allows, the handicapped people to control the wheelchair by themselves without help from others but also allows other people to use the android phone to control the wheelchair and the electrical appliance, as well as providing Qibla’ direction for the Muslims to pray.
