Multipurpose Electronic wheelchair for indoor navigation (E-WHEELS)

Mobility is one of the greatest challenges faced by elderly and physically challenged people. Solution to their problem is powered wheelchairs with automatic navigation system. This paper presents a wheelchair which can be trained to self-navigate in indoor. The main objectives is to store the indoor paths covered by the chair and reuse it for future navigation. IR sensors are used to overcome obstacles when detected, a digital compass is used to detect the direction of movement of wheelchair. This system has a manual mode for the user to train and save new paths and also for navigation in outdoor. There is also a processing unit which saves the path and which is connected through a wireless communication protocol using zigbee.
