Design and Implementation of Low-Cost Intelligent Wheelchair
The main aim of this project is to design of low-cost intelligent wheelchair. This chair is designed for physically disabled persons.
It designed to control devices and to ask others their minimum basic needs like water, food etc. wheelchair movement is controlled by using MEMS sensor which attached to their hands; based on hand movement the direction wheelchair is changed.
If the hand moves towards right wheelchair move right direction if hand moves towards left it moves towards left. The movement of the wheelchair is done by using motors connected to the controller through driver IC.
To wheel chair two modes (Mode0, Mode1) particular mode can be selected by using push button. Keys are used to control the devices when it is one mode and in same way same keys are used to tell his basic requirements through voice using APR9600 voice IC.
Devices are connected to controller through relays. The communication between wheel chair and devices controlling board is done by using RF technology. If RF communication is used we require RF transmitter connected to wheel chair and RF receiver connected to devices to control.
The system uses a compact circuitry built around AT89S52 microcontroller Programs are developed in Embedded C. Flash magic is used for loading programs into Microcontroller.
