Looks like it was trained on Shaolin Drunken Fist videos. Does it look drunk because of the videos or because there's a discrepancy between videos and it not accounting for gravity and physics in general?

My guess would be lack of actuators. For instance, this robot looks like it has an ankle that can only go up and down, but not roll like a human's. Also, I wonder if there's a center of gravity issue, as it almost always appears to be leaning backwards to even out.

I think it's still pretty impressive in its recoveries, even though there's an unnaturally large number of them necessary. About 8 seconds into the video on the homepage, it almost misses and ends up slipping off the second step. I've eaten shit at missing a couple inch curb, though I don't think "graceful" has ever been used as a descriptor for me. So the fact that it just recovers and keeps going without issue is impressive to me.

I'm pretty sure that's just a matter of reaction speed and it maintaining a constant focus/vigilance on it's movement that you'd usually not reserve outside of some sports and situations pre-identified as deserving the attention due to danger, like concentrating on balance and not getting into a position that overstresses your joints when you know it's icy.
