Dancing robots.
That is very cool.
I, for one, welcome our new robot overlords.
T-2000 is coming
That's pretty old, but still cool.
I had never seen this clip before and thought it was the dancing robot "girl" that I've been hearing so much about over the last week.

No, the "girl" looked like a human female, but I haven't seen any video of it to see if it could do realistic pelvic thrusts, or anything.I had never seen this clip before and thought it was the dancing robot "girl" that I've been hearing so much about over the last week.That's pretty old, but still cool.

Well, as somebody who actually has a PhD in robotics, I'd say it's probably mainly balance---that is, keeping the robot's center of gravity over its feet. As DrChaos said, it's got some pretty heavy batteries on it back.
Another thing to remember is that you probably don't ever want the robot's joints to hit their limits. That is, you probably never want to completely straighten the knee, or at least for any length of time. What you've got here is a very complex non-linear control system, and so you want the joints to be able to move in either direction. When you hit the limit, you can't go any further, so if you needed to go further, you couldn't, and the robot could fall over.
It's like how when you turn your amp up to 10, then if you need that extra push over the cliff, where can you go? Nowhere, because you're at 10. You need to go to 11.
