SMART WHEELCHAIR

Abstract

Many disabled people in today's environment find it difficult to perform movements or daily chores. These people are primarily reliant on others for assistance. They can, however, become self-sufficient and conduct some everyday chores on their own with the use of assistive technology. Wheelchairs are the most used assistive aids. "Smart Wheelchair" is a mechanism that provides those with limited mobility with more mobility and independence. The technology entails the creation of a wheelchair that is coupled with an Android application and offers two ways of controls, joystick controller mode and Line Following Robot (LFR) controller mode. The Android app allows users to control the wheelchair with a virtual joystick, and the LFR mode allows for autonomous movement along a predefined path. Moreover, the wheelchair is equipped with various detection features, including obstacle detection, stair detection, collision detection, and ramp movement. A seatbelt is also included for safety, activating the wheelchair's functions only when firmly fastened. The system's aim is to improve the overall mobility and safety of people with limited mobility by giving them more independence and flexibility ofmovement.
