SMART HEAD-CONTROLLED WHEELCHAIR SYSTEM

Abstract

In today’s rapidly advancing technological era, assistive mobility solutions play a vital role in enhancing the independence and quality of life of physically disabled individuals. People suffering from paralysis, spinal cord injuries, or severe motor disabilities often face difficulty in operating conventional wheelchairs.This project presents a Smart Head-Controlled Wheelchair System, designed to allow users to control wheelchair movement using head gestures. The system utilizes motion sensors such as an accelerometer and gyroscope (MPU6050), integrated with a microcontroller like Arduino or NodeMCU. Head movements such as forward, backward, left, and right are detected and translated into corresponding wheelchair movements.The system also includes ultrasonic sensors for obstacle detection to ensure user safety. When an obstacle is detected within a predefined distance, the system automatically stops the wheelchair and alerts the user.The proposed solution is low-cost, reliable, safe, and user-friendly. It reduces dependency on caregivers and provides enhanced mobility and independence to differently-abled individuals.
