Consider the way we walk... we start by effectively starting to lean
slightly forward, and we swing a leg some distance in front of ourselves
to stop from falling.  We then start to bring the other leg forward as
we reupright ourselves and repeat the process, each time stopping
ourselves from falling with a leg that we bring forward.   If we
alternate legs, it is called walking and if we use the same leg each
time, it is called limping.

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?

(...) Hi Mark, I have never seen a walker like this. I'd be the last person to say it can't be done. Kevin (...) (21 years ago, 18-Dec-03, to lugnet.technic, lugnet.robotics)

Now, think about what physically goes into making yourself walk. How much energy and control is involved? Try walking on a flat, level surface (or better, one at a slight decline, like a very long handicap ramp). Walk with your natural gait, at the (...)

(...) Parallax markets the Toddler, which is a walking Robot that shifts its center of gravity to walk. It turns by sliding its feet in opposite directions. It has 34 possible movements. (21 years ago, 19-Dec-03, to lugnet.technic, lugnet.robotics)

Lots of responses to my post, so I'm following up my own post to address all of them. A lot of people are pointing out that this has been done before in the field of robotics, but what I was actually asking about is if it's been done before in (...)
