Improving the mechanical design of new staircase wheelchair

Purpose This paper aims to present a new stair‐climbing wheelchair that tries to solve adaptability problems of previous prototypes. Design/methodology/approach A new prototype has been built using a new strategy. The climbing process is splint into two subproblems: climbing a single step and positioning the wheels on the staircase. Findings An optimized solution has been found for each subproblem, due to this the presented prototype is able to...
