Last year we had a two-wheel drive robot that rolled very easily. We also had a cart that rolled like it had square wheels. We got tired of it and finally just rolled the robot from the pit to the field with no cart at all. We loved it because we didn't have a cart to move out of the way or try to maneuver through the pits in Chicago. We did use our cart in Atlanta, though, because we didn't want to roll the robot that far.
