SOLAR POWER MOTORIZED WHEELCHAIR-DESIGN AND DEVELOPMENT

Electrical Engineering

This project aims to develop a Solar based Wheel Chair System for the physically handicapped people at an accessible cost. An assistive technology known as motor controlled with solar power chairs is used to deal with loss of mobility for the patients who are not able to walk normally due to some injury or some other age related walking disabilities (permanent or under treatment). There is a vast development in the field of wheelchairs. Researchers are going on to develop reliable, low cost and easy to use devices. Out of all the advantage of using Motorized System when patients become completely paralyzed, the only resource available to them for moving is wheel chair. Non bio-signal based devices provide 100% accuracy and require less training for patients but the usage of these by using the solar power for charging of the battery flexibility in usage increases .Wheel chairs is limited to patients with partial or complete flexibility in their body parts.People are switching over the renewable source of energy for their requirements, Solar energy is one of the source which is free of cost and present in abundance so by automating the wheelchair with the help of power generated by solar energy it can cut the overall cost of fuel and become eco-friendly in nature and can set a limit in the world of Automation. In this paper “Solar Powered wheelchair”, its construction, working and component used is studied in detail, and all the project work is done in Nagpur In today’s world there are many disabled persons who find it difficult to perform movements or perform daily activities. This types of persons are mainly dependent on others for their assistance. But they can become self-independent and perform some daily activities on their own with the help of assistive devices. The most widely used assistive devices are Wheelchairs. Wheelchairs is basically a chair fitted with wheels, which can help people move around who cannot walk because of illness, disability or injury. But there are many disabled people with weak limbs and joints who cannot move the wheelchair. Thus, Smart Wheelchair can benefit a lot to them and everyone in society. Smart Wheelchairs are electric powered wheelchairs with many extra components such as a computer and sensors which help the user or guardian accompanying wheelchair to handle it easily and efficiently. The recent development in the field of Artificial Intelligence, Sensor technologies and Robotics help the growth of wheelchairs with new features. This paper is to review the current state of art of Smart Wheelchairs and discuss the future research in this field.
