Innovative stair climber using associated wheels

Girish Sudhir MODAK,Manmohan Manikrao BHOOMKAR

Frontiers of Mechanical Engineering 2016, Volume 11, Issue 3, Pages 299-310 doi: 10.1007/s11465-016-0374-1

Abstract:

The study proposes an innovative and completely new but low-cost configuration of a platform that can easily climb stairs. This platform serves the purpose of a chassis. Different versions, such as staircase-climbing wheelchair or staircase-climbing trolley for material transferring, can be derived depending on the structure built on the platform. The driving wheels have a shape that completely matches with the profile of the steps. Complex components are eliminated. Thus, this platform is conveniently applicable in the configurations useful for climbing staircases.

Keywords： stair-climbing platform matching wheels impaired mobility affordable configuration
