that's frigin insane. probably not too many people on DA understand that this isn't an animation but that it's a physics simulation.
I would like to see the legs able to pitch forward more so it could walk further each step, but to compensate for the longer time the foot would be raised you could rotate the grounded foot to keep it balanced. Just an idea, not trying to impose anything on you.
I'm assuming you're not a sketchup user and thus you're definitely not a sketchyphysics user. Sketchup has no efficient way of taking videos other than taking snapshots (there aren't even plugins to do that)
if you don't believe that it's a model with physics then look at his earlier robot (sketchup.google.com/3dwarehous... and download sketchup and sketchyphysics which are both free.
it may not be wobbling because he might be using gyroscopes, which make it significantly easier to keep it upright (cheating or not it's still a very impressive accomplishment)
Your link appears to be broken. I've downloaded SketchUp, and it does appear to run on Linux under Wine. I haven't found a downloadable version of SketchyPhysics. Maybe I should try the Windows version.
True, I'm not, though I used to use SketchUp for architectural modelling. At that time it was recommended mainly for modelling buildings for display within Google Earth. You could find some examples in my Gallery.
I'd like to use it again, but that will not be as straightforward as it was then, as I now do everything on Linux. There is no version of SketchUp for Linux, to my knowledge, but I'm hoping it can run under WINE.
I didn't know about Sketchyphysics. Very glad to learn of it through you. I hope both turn out to be free in the Open Source sense, though Google's track record in that respect has not been stellar.
