Design and Construction of Smart Wheel Chair

Abstract

Nowadays, more and more inventions and researches are carried out for giving aid to disabled persons using different strategies. In order to make them feel independent simple automatic techniques have to be developed for movement of wheelchair and so on. These kinds of wheelchairs are getting more attraction during these days as they are easy to handle and use. This project deals with hand-controlled and Apps controlled wheelchair where the movement of a wheelchair is controlled by hand and Apps have given to Arduino. Along with this obstacle detection is also carried out using the ultrasonic sensor. It was also able to run a challenging place like this wheelchair is able to run on a stair. According to research, there are about 6 million populations in the world who are paralyzed or disable and need a wheelchair for their mobility. Earlier the wheelchairs had to be moved and be externally supported by any person. To help overcome this “Smart Control and Automated Wheel Chair for Disable People” are developed. But in regular use, these joystick-controlled wheelchairs became difficult to use. Especially in the case of paralyzed people, the use of joystick became more difficult due to the hard buttons and unidirectional use of the joysticks. To overcome these problems, This can be used in both hands and can be controlled to come to the user from a distance. The current work is implemented with Arduino based devices such as Arduino UNO processors and programmed through Arduino IDE.
