Smart wheelchair based on ultrasonic positioning system

We present a robot wheelchair based on a UPS (Ultrasound Positioning System) for the elderly or the disabled. The proposed robot wheelchair system, called Smart Wheelchair, is a standard powered wheelchair equipped with a laptop computer which supports a variety of GUIs (graphical user inter-faces) for the disabled and a microprocessor system equipped with UPS and external connectivity modules. The Smart Wheelchair incorporates state-of-the-art technology providing information about the location of the wheelchair based on its movement, which is beyond comparison to ordinary wheelchairs that have just one function: to move patients. The Smart Wheelchair can provide users with driving assistance and take over low-level navigation to allow the user to travel efficiently, safely and easily.
