Two Legged Robot Sets Speed Record 149
An anonymous reader writes "Researchers in Germany and Scotland have made the fastest two-legged robot yet (for its size) called RunBot. It is controlled by a simple program that mimics the way neurons control reflexes in humans and other animals. From the article: 'We wanted to show that a very simple system with a simple neuronal controller could walk in a natural manner - and fast,' says Florentin Wörgötter, from the University of Göttingen in Germany. The story also features couple of videos of RunBot in action."

replace the word "legs" with "about 27cm" (from the looks of the thing).
Also, from the video (which is kind of silly), it looks like it's attached to a pole, which may mean it can't stand or walk on its own (certainly not without power or instruction, but maybe also not without physical guidance). I donno, neat toy at any rate.
PS, I mirrored the video here [tenthousandpercent.com]. Yeah I'm taking it down in 24 hours.

Probably just to stop the experiment needing a shitload of space without worrying about explicit turning. Of course, you could have just quoted the entire paragraph (two sentences) - bold face added:
RunBot currently walks around the edge of a circular room and is connected the centre of the room by a boom. But Wörgötter plans to develop a freestanding version next, and thinks it should be straightforward because the boom has only a small influence on its ability to walk.
Doesn't seem quite so problematic now, does it?

This isn't the first time we've seen great mobility from tethered robots, but somehow these guys never manage to produce the untethered version. Getting power and proper balancing to an untethered robot seems to be the critical stumbling block and I would be shocked if this one doesn't hit the same issues.

As to the whole walking thing - it's a fascinating topic I think:
1) walking is a controlled fall, the only thing preventing you from going face-first into the pavement is that next foot fall.
2) Maximum cruising speed is attained in a single revolution. No other animal or engine can claim the same (AFAIK).

1) stand still.
2) begin walking.
3) measure speed after single step.
speed = cruising speed.
ipso facto: 1 revolution = cruising speed.
And in fact, it's more like HALF a revolution, because two steps is a full revolution.
Other animals can claim to achieve the same effect for their walking gait, but none can claim the efficiencies of the human gait, in terms of calories expended per kilogram carried per kilometres traveled.

In all seriousness though, in the video it looked like the robot wasn't balancing itself.
