Embedded Wheelchair Controller

Work presented in this paper is about IOT based wireless control of motorised wheelchair used by patients both for self-use as well as remote control by third party. Wheelchair is moved in different directions based on the differential voltage applied to the two wheels. Digital control techniques are superior however, it is very appropriate given the trends of utility is being made on top of android mobile phone to use a mobile phone based wireless control for such purposes. This enables the common people to use the system since there is no significance learning curve and it gives the digital stability to the system which is not dependent much on environmental variations and user interface is made much simpler.
