Re: Smaller Diameter Wheels - What's the advantage?

Compared to our older robots, everything was the same except going from 6 6" to 8 8" wheels. Without getting into gear ratios, we are getting a hell of a lot more torque and pushing power.
As far as CG goes, we adjusted for it, by placing everything a lot lower this year as it was well-suited for the game. We like it so much that I think we are sticking to 8" wheels hopefully for next year.
