Advancement in Solar Powered Wheelchair by using Intelligent Electronic Devices

The paper proposes an automatic Wheelchair which will help the physically challenged people and serve as a complete and save means of mobility. It is an automatic wheel chair which requires less secondary assistance and moreover is self-propelled. The desire of self-mobility can be fulfilled by this chair. It also focuses on the safety of the person. This is a doubly powered device which runs on solar as well electric energy. The renewable energy is harnessed therefore there is less stress on electric energy. When used outdoor it can benefit the person by saving energy as well as on the other hand switch to solar energy. As old people are not so quick in action their safety is a major ensured by providing the obstacle detector by using ultrasonic sensor. The GSM system is also facilitates the safety by further providing messaging facility when the person is in danger. The DC gear motor is used easy speed control is achieved and even direction can be changed. The ultrasonic sensor is used to detect the obstacle and further operate the panic switch ensuring safety of the personnel. The entire analysis has been carried out in this paper.
