Disabled Persons are one who has either legs or hands and it is duty of every individual to safeguard them. Government is helping through various schemes by supplying wheel chair etc. there is need for sophisticated vehicle for them to work in the factory by moving inside the factory premises, moving inside the house premises and office premises. The primary objective of this project is to develop a vehicle for Disabled Persons especially for people without legs. Hence extensive research was carried out to come out with this idea and its methodology by Voice of Customer and Quality Functional Deployment (QFD) analysis. Here handle bar is used with accelerator and brake incorporated. The Permanent Magnet Direct Circuit (PMDC) Motor is used in the brake drum driven by battery / solar current since this is a vehicle primarily designed for Disabled Persons, the vehicle is designed considering their disability in mind and much importance is given regarding the safety of the passenger after. Hence driver ergonomics plays a key role in the designing of vehicle for legless persons. Handle bar designed to suit both manual steering and electric steering. Chassis design and center of Gravity is calculated and the Brake is kept in the Handle Bar.
