Dunno but this non-LEGO robot (with knees) has been taught to run

I wish there was a video available on the net somewhere - I saw it on TV
yesterday, and though it's difficult to tell it's running, it does seem rather
more "human-like" than most walking robots I've seen.
I'd also be interested in seeing a robot that more accurately imitates 4-legged
animal gaits - being able to walk, trot, pace, and gallop.
