Abstract: This article deals with the designing and manufacturing of a Stair Climber, considering the aspect of wheel modification .Stair climber is the vehicle which can climb stair or move along very rough surface. The technical issues in modification of wheels of this vehicle are the stability and speed of the vehicle while climbing stairs. However, the steepness of the stairs is also the important concern of this study. The uses of this special vehicle are in the frequent lift of goods such as books for library, medicines for hospital, regular mails for any institutes, or transportation of any toxic material for industries and give freedom to the retarded person or paralyzed patients to move anywhere over flat surface as well as stairs. Wheel of Stair Climber is modified on the basis of Different criteria like strength, cost, and mobility etc. using complete product design approach. Different types of Stair Climbers are analysed like Legged Stair climber, Wheeled Stair Climber and tracked Stair Climber .On the basis of different criteria it was find out that wheeled Stair climber is better than other Stair climbers. Pugh chart is used for selection of best concept for different wheel climbers. Using of this vehicle, the labour cost can be reduced as well less power is consumed for lifting of heavy loads. Moreover, considering some drawbacks due to lack of implementation of all techniques during manufacturing phase the test and trial run showed considerably significant and encouraging results that might help the future researchers to incorporate a gear box and steering mechanism to make the vehicle more versatile.
