    It must have one heck of a gyroscope inside. Pretty impressive indeed. What was the deal with it jumping? They programmed it to do that, or it recognized the pink below and made sure not to land on it?

    The jumping of this robot somewhat goes into the roots of how it works... for a long time the 'traditional' way we envisioned robot movement was along the lines of Honda's ASIMO style, very calculated, slow, just like the 80's dance.

    hehe this is a good one... yes... face plant for the investors!





    Then some got the idea, hey that's now how we move until we're 80, nor is that how animals move. And a lot of projects began to watch the locomotion of various animals, snakes, pumas, kangaroos, etc. Once we got a good understand of how they don't fall over and why, some came up with 'jumping bots.' MIT Legs lab did some great robots that looked like plungers running around. Basically these robots that don't stop, they always move. "Big Dog" seems to be somewhat of a mix, but defiantly has its roots in the jumping category.

    While big dog looks sad on the ice, it's truly amazing. I'm not even that skilled on ice, falling 3 times leg up in the air style this winter alone!

    but sigh... It's only a matter of time before big dog is scrambling to my car with an attached taser accessory and ticket printer.

    This is actually related to my field (biomechanics of animal locomotion), and I know the guy they consulted with for this robot. The difference MrFlytrap is talking about is dynamic vs static stability. In robots like Asimo, the robot is always stable - you could hit 'pause' at any time and it wouldn't fall over. The same is not true for real animals, who 'bounce' as they walk and run. Overall, they're stable, but only due to repeated applications of force via the legs, which is why if you disrupt the pattern (say, by tripping them), they fall over.


    Also, I'm not sure this thing uses servos. It sounds awfully like it's got an air compressor, especially with the 'clicks' in the externally-powered one. Pneumatic muscles are actually being used more and more in biomechanics, since they simulate some properties of real muscles (such as the length-tension curve).

    4 legged robot looks clumsy and slow. I suggest they make a robot in the image of a large centipede with red glowing eyes, an exoskeleton made of steel, and sharp metal legs. That way it'll have stability, traction, speed, and powerful mandibles that can tear human flesh.

    That sounds more plausible better holding power,a air compressor and an air tank that sounds better I did not listen to the clip... The holding to energey ratio would be better.. The human form is less practicle for robots bipedic movement for robots sounds more complex and harder to control. Okay that has to be an air compressor
