The main objective of the project is to provide stability to the person when climbing the stairs. A disabled person with lower limb does their daily activities on wheelchairs. The disabled person encounters difficulties when they have to ascend or descend the stairs. This leads to a risk of injury for both the disabled person and the assistants. Therefore, this project presents a prototype of a stair-climbing system for a wheelchair. This research was aimed to enhance the quality of life for the lower limb disabled person by enabling the wheelchair to climb the stairs with only one assistant to control the wheelchair. The designed stair-climbing system consisted of two 5-spokes wheels and the slot plates. The 5-spokes wheels were used for climbing the stairs. The slot plates were used for sliding the rear wheels of the wheelchair. The 5-spokes wheels were installed at the rear of the wheelchair and were driven by power from an electric motor. When climbing the stair, the rear wheels were slid to the front of the wheelchair. To move on the floor, the rear wheels were slid back to the rear of the wheelchair. From test results, the wheelchair with the stair-climbing system could ascend and descend the stairs with the maximum riser height of 200 mm. The maximum payload was 80 kg. The stair-climbing system could reduce the number of the assistants to only one person and the wheelchair could still move on the floor as a general wheelchair.
