An Intelligent Wheelchair for Disabled Person

Every new development in sensors and ultrasonic technologies has always been a bonus for electronics traveling aids (ETAs). This sets way to the development of smart vehicles for disabled people. These smart vehicles are used by physically disabled people. This electronic intelligent wheelchair is designed to help disabled people to move independently to any place without a caretaker. It consists of a smartphone app-based operation along with obstacle avoidance, fall detection and narrow way locomotion. An android application is used to control the wheelchair. This smart chair can function in full automatic mode. It uses GPS-guided system and magnetic compass to determine location and stores the location to return back to the location automatically. The fall detection system tilts the seat when it moves around any inclined plane and alerts the nearby caretaker with an SMS when a fall is detected. It has an intelligent collision avoidance system to avoid any type of obstacles including potholes and can move around narrow pathways and doors without being hit or bumped against any obstacle.
