Head-Motion Controlled Wheel Chair Direction Using ATMega328p Microcontroller

Abstract: Wheelchair is a device used to move physically challenged people or patients from one place to another who are unable to walk by themselves. The main aim of this paper is to prepare a Head-Motion Controlled Wheelchair for physically disabled people who cannot move by their own. Electric wheelchair are very expensive and costs more than 60000 Rupees. Standard wheelchairs are controlled manually by means of other persons or self-propelling. Head-Motion Controlled Wheelchair is an electric wheelchair which can be controlled by head movements of the patients or physically challenged people and does not require any effort as it works electric motors. Accelerometer is used to sense the forward and backward movement of head which can be used to control the wheelchair forward or backward respectively.
