Dancing robots.

That is very cool.

I, for one, welcome our new robot overlords.

That's pretty old, but still cool.

I wanted to see some hand springs and stuff. I wonder why they can't get them to stand up straight. They all keep their knees bent.

Remind me to be in my goddamned bunker when SKYNET goes online.

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.

Wow, talk about human rights violations. They're making side shows out of those midgets. How de-humanizing!

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.

Think it's a balance thing. Same reason fighting stances keep the knees bent.

I figured it was a balance thing. But why to that degree? Would they fall over if the stood up? Why? Not that anyone here has the answer. . . was just something I wondered while watching it.

It's probably a counter balance to the power pack on its back. Otherwise it would be heavy in the caboose.

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.

Back to the bent knees, if they weren't bent and a heavy adjustment needed to be made to keep balance, then all that force would need to be applied at the ankles. I would think that would torque the hell out of those joints.

Nothin an oil can can't rectify.
