DESIGN OF LOW COST ARM CONTROL ROBOTIC MOVING WHEEL CHAIR FOR ELDERLY & PHYSICALLY DISABLED PERSONSAbstract
This paper deals with the concept of design and implementation of a low-cost model of an arms control moving chair using ATmega8.This moving chair can move forward, backward, left, and right. This is done with the movement (tilt) of the accelerometer, and the chair stops when there is no movement of the accelerometer. The values of the three-dimensional axis of the accelerometer can be varied and adjusted. The programming has been done through AVR compilers and burned into the ATmega8.The ATmega8 receives the information from the accelerometer and transmits it back via RX and TX pins.ATmega8 has also been interfaced to motor driver IC-L293D, wherefrom the connections go to two motors to drive the wheels of the chair. This model has been successfully implemented at a low cost, and it will benefit physically challenged persons, especially with the poor background.
