One of the problems I'm faced with when doing mech designs for Griffon, is that the "chicken leg" design doesn't work for large robots.
Despite that it looks totally awesome, it would require either an extremely light chassis or incredible metal for any moving joints.
And this is a problem even for a small mech. Anything over the size of a small car would be too much stress. The chicken leg design is definitely not feasible for a large mech. If you've ever built something even a little larger than a human, that has joints, you know what I'm talking about.
WAIT A SECOND! What about Dinosaurs?
That got me curious. So I looked around, and came up empty. Oh I found a lot of people who claimed this or that based on 'computer models', but either they're 'doing computers' wrong, or they're just wrong. I can't imagine the current info on theropod walk cycles is correct, because it's not even practical for a *metal* dinosaur.
I drew you a picture that explains the problem.
I have a number of Paleontologist, Biologist, and mechanical engineers as friends, so I'd be really, really happy to be proven wrong about this. That's the thing though--I need actual proof. So if you know of any papers or theories that might explain how an 8 ton creature could walk on two legs, with theropod leg structure, please let me know!
