Has anyone ever tried to build or design a bipedal walker that imitates
this form of motion?  I'm thinking that it probably wouldn't even be
possible to do without flexible knees.  Is this level of sophistication
even implementable in LEGO to the point that it's genuinely useful and
not just a proof-of-concept?

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.
