Normal person can travel easily by utilizing the facilities such as bicycles, bikes, cars, public transports, etc., but for disabled persons travelling is not so easy. Depending upon the disability (i.e. which part of body is not in function),

Manual wheelchairs are largely used in hospitals, which are generally driven and controlled by helping person. If the user himself is operating it, the controlling and driving of wheelchair is done by hands only. But as compared to legs, the hand work is less efficient and more straining; this leads to lower physical capacity of user. Therefore long term of use of manual wheelchairs is not advisable.

To reduce the local discomfort and fatigue other propulsion mechanisms are available now. This alternative mechanism reduces drawbacks of hand rim driven wheelchairs. Many experiments on lever and crank propelled wheelchairs have shown reduced straining and more efficient working. The tricycle like arrangement as shown in fig.2, in using these mechanism proper movements of arm shoulder joints is happening, which allows the higher velocity of travel with less physical strain. The new design of wheelchair is improved by considering the guidelines of ergonomics; also many innovations came in picture to improve the suitability of
