Abstract:

This work presents the development of a robotic wheelchair that can be commanded by users. It provides flexibility to choose different modalities to command the wheelchair, in addition to be suitable for people with different levels of disabilities like partially paralyzed, by birth disabilities, accidental injuries etc. Users can command and control the wheelchair based on their head movements. Also, the user can control some home appliances. As a trial, we work on the lighting system in a room that is ON and OFF mechanism of a light. The wheelchair can also operate like an auto-guided vehicle, with the help of obstacle sensors, which detects the obstacles in front of it, and it either stops or takes deviation. A main door detection section is provided with a magnetic sensor in the wheelchair and a magnet fixed at the main door for safety and then the wheelchair stops. A security as well as a safety alarm is provided in the device, which beeps when the device may hit somewhere or an emergency situation occurs. Head movements are used for both moving the device and for controlling directions of the device. This device is capable of lighting the room by eye movements.
