Researchers and scientists have contributed a lot for handicapped or physically disabled people to adopt techniques that may help to smooth their mobility in daily life reducing their painful effort, instead of being dependent on others specially while using traditional tools like wheelchair. Many people continuously need help of someone while moving somewhere with the wheelchair. By having an automated control system incorporated with the wheelchair, they would become more independent. The main goal of this project is to fabricate an android controlled wheelchair using Arduino, which can be navigated easily by disabled people with own effort. The inputs will have to be provided through android application which has navigation control and other features, also this application is integrated with home automation system for controlling home appliances. This wheelchair is able to detect any obstacle or crack on the path towards the direction of motion and alerts the user with the help of sonar sensor and IR sensor. The enriched results of this project fabricated a path for further advancement of this technology and finally being manufactured. Please take a look at this link; https://bit.ly/2NStcZ9
