If your robot were traveling 35 MPH, it'd be able to cross a football field in six seconds. Can it?

We did have trouble tripping the breakers. The first time we tried it out we only had one CIM per gearbox, but we added two more. The road we tested on had a slight hill, so if we started off in first gear and shifted into second it did fine. As for the football field in 6 seconds, it would be close. I need to find a radar gun somewhere.
I admit that it isn't practical and we wont use this setup on our robot next year (most likely), but it sure is fun.
