hmm, with a leg configuration like this - how would you handle
Turning. I was thinking about the brute force method of one motor
for lego motions and two for just picking the whole assembly up and
rotating it. Not very pretty, but.... anyway... With a separate motor for
each leg pair - this would be difficult.
wait a minute - hmm,
I have seen a few leg designs where the motion is 90 degrees to what I
was attempting. If using the three motors you keep the center motor
stable, and have the outside motors moving in reverse of each other - you
could probably have the bot turn. I'll try this and post some pictures this
weekend....
Again thanks for the response....
