Interesting leg actuators on this stair climbing walking chair thingy . . .

The walker is very interesting – but I can’t tell if it has its own stability control, or if it’s just being controlled by a very skilled driver. It looks kind of tippy in any case, and I’m not sure I would want to try it out on the stairs! I got the feeling from the sound, that the actuators might be linear motors, or leadscrews, as opposed to pneumatics, but I can’t tell for sure from the resolution of the video.

I wouldn't want to tumble down the stairs sitting on that thing. Appears that would scale up from a few bruises and maybe a broken bone or two, to a broken spine/neck and crushing injuries.
Maybe a roll cage?

I'm under the impression that the Honda robot (the name escapes me for some reason) has to have steps made for it.
I think with this one, the same would probably apply.
But then, i'm probably jealous. lol.

Oh I forgot to mention that I saw an ICRA presentation by the guy who worked on the actuators for this thing. They used dual linear actuators - a single motor that pushes a rod up and another rod down.
This effectively doubles the speed of the actuator.

Toyota has some of those chairs as well.
