Abstract—In field of providing mobility for elderly and disabled, the aspect of dealing with stairs continues largely unresolved. This thesis focuses on presenting the development of stair climbing wheel chair mechanism with high single step capability. The mechanism is based on four wheeled cluster connected to base via. Powered linkages so as to permit forward direction and high single step functionality. Primary considerations were inherent stability, restriction of size, aesthetics and low cost. This research work presents a design of a mechanism that aims a wheel to climb steps of 220 mm high. The proposed four bar mechanism installed on each wheel of assembly. Which can be capable to climb stair height suitable comfortable motion. The compactness of the mechanism design makes it suitable for staircase climbing assembly for aiding people with disability.
