Well, after speaking briefly with AoP, who advised me to post this here, I have an idea for a walking system for a mech. I don't know how open you guys are to new ideas (if you're close to finalizing or want to stay with the BT theme) but here goes:
I looked at the newsletter last night and skimmed over the mech models, and they were all conventionally bi-pedal. I found that a little boring and had a few interesting ideas flash through my peanut sized brain. The most viable one would be somewhat of a two stage walking system for a new model. BTW, I don't have any decent progs installed on this POS right now, so I can't draw any images, not like they'd be viewable anyways... LOL.
Lower Leg -- the "calf" would be significantly out of proportion with the thigh and much, much longer. It would resemble a motorcycle fork and have a tank tread (foot) half the length of the "calf" inside the fork.
Upper Leg -- the "thigh" would be half of the length as the foot and would be sandwiched between "calf" and the body.
Movement -- for sprint obviously you could roll along the tracks at high speed along somewhat even surfaces. Like a giant skating mech.
Walking however would be an entirely different story, what would happen is the foot would rotate in side the calf and the thigh would move in a train like manner kind of hard to explain but with a little imagination I think you'll get it. It'd be intresting to see something a little unconventional.
With the walking it would give a very "even" ride, to allow for easier shooting, and you could handicap this benefit by limiting either speed or turning ability.
Let me know what you guys think.
