The proposed system consists of a wheel chair the benefits and modification to facilitate climbing of stairs through its special designed features. The purpose of this work aims at developing an automatic Stair-Climbing Wheelchair, a mechanism for climbing upstairs and down stairs for physically disabled people. A Stair-Climbing Wheelchair is a chair that moves upstairs and downstairs. It has speciality to maximize comfort, ease the usage and attractiveness in the home, which is a safe and affordable solution to conquer the challenges that disabled people experience on the stairs. A unique mechanism for climbing stairs, used here is a tri-wheel mechanism, due to its simplicity and ease of design. The tri-wheel mechanism can be easily fabricated, thereby reducing the total cost of fabrication of wheelchair. The tri-wheel mechanism for stair-climbing wheelchair makes it easy to move up and down on stairs. The smart wheelchair is designed to assist disabled and elderly people leading to a higher quality, more independent lifestyle
