Re: Odd 8 Wheel Tank Drivetrain Idea

We used it in autonomous to get the second hot goal. During tele-op, we mainly used it to get out of t-bones; we could easily spin out of a perpendicular friction pin. For actual maneuverability on the field, it never saw too much use other than maybe adjusting for shots near the one point goal.

If I would change something about what we did this year, it would probably be to not use the center wheel and instead go for a 6 CIM single reduction with the same setup of omnis and traction wheels. We ran 4 CIMS this year because two were being used on the center wheel.

In a game like 2011, it could definitely be useful, and I believe 148 had originally planned to use a nonadrive again that year, but then left it off and went with what became known as butterfly, or now "Tex-Coast Drive." Why they chose not to use it I'm not sure, maybe someone from 148 can expand on that.

If we ever get around to it, something I would like to see is putting the traction wheels in the center and omnis on the outside; the idea being you can still turn on a dime even when in traction for more controlled turns.
