It does if you have 400 years to let it think about it.

Why the hell is that thing walking on top of those obstacles. Think about how a human would walk through that: cherry-picking the floor spots between the debris. If we step on one of the boards, we're not going to try to make our foot work partway on the debris and part on the floor. We're going to use the ball of our foot to plant in the middle of the board, then roll over the top of it, letting the ball of our foot rotate with our fibula as we pendulum through. That things trying to walk through it like one of the idiots in Dumb and Dumber. Totally weird approach.

To be fair, we humans attempt to avoid walking on those things too.

It is kind of a weird approach (and probably just narcissistic) to bother making a robot bipedal in the first place, when you have total control over its form. If it's really going to be doing any lifting, carrying, navigating difficult terrain, it's going to be better at it with more than two legs. But I guess this project is about trying to make a robot move like we do.

True, but I don't believe that's what they've done in this instance. We avoid obstacles unless we're in tanks.

I get the feeling that this is "phase 1". Once they get past the difficulty of keeping a bipedal robot upright in worst-case scenarios, they're probably going to work on some kind of obstacle/environment recognition system.

Agreed, it will evolve. I think that the worst-case scenario here is worse than what humans can reliably deal with. Put blinders on someone and have them walk through that. You'd have some falls and stumbles. It seems like now is the time to work on step placement strategies. Then again, what we're seeing may simply be training for Atlas, and after a couple weeks of this, it will be tipping through the gaps and stepping up on the stable ledges consistently...

Like any complex system a good initial design gets polluted by the spaghetti required to make it work. You can almost see the hacks in the ankle and hip movements with the delays to start jittering and that it always moves forwards first to balance.

What I don't understand is why they insist on going with bipedal robots. Two legs are inherently unstable and can lead to the uncanny valley that we all want to avoid with our world dominating robot design. 4 legs, wheels or tracks make much more sense and is why we have these bomb disposal robots on wheels and not legs.

Oh well, put enough gyroscopes on a broom stick and you can make it stand up.

Sounds to me like they need to add in some recognition algorithms. I recommend this:

That's no longer as bad as people think. I've worked with some very well implemented commercial JVMs. Computers are fast and cheap enough these days that you can just jam more cores on it to make up the now small differences between a virtual machine and native code.

Its also easy, open, and well supported with a very large community. Much smarter to write in that kind of language than something that may be easier but isn't open or well supported. Programmers need Google.

I just think its hilarious that they want a humanoid robot so bad when the fact is different designs would be far superior for the tasks at hand.  Humans need to adapt to challenges... robots can swap out parts.  Advantage:  robots.
