Wheelchair climbing stairs GIF

[Frank S]

I don't know how architecturally. Aesthetically appealing I would call their solution. But I would most defiantly class those stairs as a health hazard.
I count at least 2 dozen possible toe stumble points. At no time should any tread ever extend above ant landing either horizontal or inclined thereby creating a possible place where a persons toe or heal of their shoe may be caught . All of those treads should have been ground away to the same level of the inclined ramp. Additionally most safety codes require a handrail to be within a persons extended reach from any vertical assent or decent path of a stair . this would mean that there should be at least 2 additional sets of handrails going up the stairs.
As for the tracked chair that looks like a variant of the one a man by the name of William Robertson of Robertson machine was developing before his cancer overtook him in the early 1990's
The thing he was working on had a positive lock ratchet to the tracks in case of some mechanical failure. and his cylinders were electric linear actuators ( screw jacks if you will).
