Are idea is the walker coaster and it helps people get up and down the stairs with a walker independently. Essentially we will build a contraption to attach to the railing of the staircase to carry the walker up the stairs.
-what if your outside
-balancing on only on the railing
-how would the front legs go up cause it sounds that the legs of the walker would just hit the stairs
-the railing might have to much friction keeping the walker from going up
-brain storm just helping up the stars or just get it up the stair
-portable or nah
