Last year, I calculated our robot to a gear ratio of 13ft/sec. Realistically it went aroun 10-12ft/sec.
It was a 2.66:1 gear ratio, or 48:18 gear tooth ratio. We were ~75lbs only that year.
If you want a fast robot that you do not expect to be carrying a load, feel free to use our gear ratio and gain from our experience using it. We had the drills at high gear that year, btw.
