This prototype, called the Scalevo,
has rubber, tank-like treads mounted to the bottom of the chair. The
user approaches a set of steps backwards with his or her back facing the
steps. The treads sprout out, lifting the chair up at an angle,
allowing it to crawl up the steps.
The user is kept level at all times.
The headlight-and-taillight-equipped chair has two extra sets of wheels
that pop out at the last step to provide smoother transition back to
flat ground.
