The proposed project envisages designing and fabricating a wheel chair equipped with versatile features aiding the physically challenged person to have more mobility while moving through various surface. The major challenge faced by the existing designs of normal wheel chairs in the market is their inability to climb steps even with the help of a bystander. However the existing step climbing wheelchair are designed only for that purpose and not economically designed for movement through flat normal surfaces. The proposed design of the wheelchair alleviates aforesaid disadvantages and is able to climb steps, move more easily through flat surfaces and rough terrains and more importantly it is economical. The proposed wheel chair employs caterpillar track mechanism. The centre of gravity is controlled by hydraulic shocks. This type of traction belt is responsible for contact with two steps at a time, thus enabling the wheel chair to move up or down over the steps. The forward, reverse and sideways motion of the proposed wheelchair is controlled with the aid of an electric motor and steering is operated by a mechanical pedal. This innovation made the wheel chair highly versatile and flexible in application.
