Abstract
Ability to walk and run through different terrains is ability with which as humans we are blessed with but due to many unfortunate happenings or some deficiency many people lose this ability but with the advancement of technologies several mechanisms are devised for such people wheelchairs being the one. Some limitations with them is the mobility while moving through stairs thus this paper works on designing and studying a mechanism which is able to climb on the stairs . The proposed design is drawn on Solidworks and a 3D rendered view is obtained using keyshot. Considering the standard stair norms required force analysis has been done considering a no slip condition. Further calculation of the design parameters for the mechanism has been calculated at stable state.
