First of all, I think all the threads involved with "the drivetrain story" are GRRREAT. Kudos to Patrick Wang for getting us going on something important. I was even inspired enough to go buy a CAD program.
Anyway, what I really posted for is I was wondering how many robots use treads instead of wheels? Does it give that much more traction? I would personally use them for the coolness factor alone but the pulleys are between $80 and $120 apiece!!! How hard would it be to make our own. Could it be done on manual mills/lathes or would we need CNC.
What CAD program did you get? Also, while an NC machine isn't required to do belt pulleys, it would save time and effort. You could use a thing called a dividing head on a manual mill. It could also be used to make gears.
