Multicontroller based Wheelchair Safety using Android, Touch, Speech & Gesture Control

Download Project Document/Synopsis

Locomotion is one the basic needs of humans which is lacked by people having limited abilities which render them to use wheelchair for moving from one place to another. The purpose of this project is to serve these people by automating the process of moving in any direction using Different methods over Raspberry Pi.

This project is based over Raspberry Pi as its core processor. The objective of attaining automated locomotion is obtained by using different interface as follows. First kind of interface is touchscreen in which displays arrow keys so that the user can move in any direction of his/her choice. Similarly wheelchair can be controlled using Hand guestures, Voice, as well as android phone. The wheelchair circuit consists of a RF and Bluetooth receiver used to receive these commands and then operate the wheelchair motors in order to achieve desired movement. This allows the disabled person operate the wheelchair easily as well as another person can operate the wheelchair from 3-4 meters distance.So in this way, the wheelchair system is taken to a new level by the usage of automation and safety to the user using the Raspberry Pi based Wheelchair system.
