Re: Direct drive minibot - output diameter?
We have a ~1.8 second minibot that is very consistent, and we don't have access to a lathe (due to some stupid crap... There are three lathes in the shop in which we work, but we aren't allowed to use any of them due to silly school politics that six years of effort have not circumvented.)

We modified and kept the gearbox, but removed two stages for a total 5:1 reduction. We then added custom wheels that are machined to match the radius of curvature of the pole.

It is very consistent and pretty fast, but not as fast as, say the Thunder Chickens' press-fit 1/4" (or maybe it's 3/8") direct-drive minibot.
