I am more than pretty sure, I'm certain that they have a crab drive.


@EagleEngineer:
Sideways movement does not indicate mecanum.

Mecanum, kiwi, slide, crab and nonadrives can all move sideways. I personally prefer crab or nona because they sacrifice little forwards power (with nona/slide you still can still put 4 CIMS to the forward direction, and add, say, two banebots to the slide wheel, with crab you can orient all wheels forward for maximum forward power)

(for those who don't known a Nonadrive is a 9-wheel slide drive, with articulating traction wheels. It was named by JVN, who is obsessed with the number 9. It was used by teams 148 and 217 in the 2010 seasons, and almost used by team 148 in the 2011 season (they pulled the slide wheel, but keapt the lifting traction/omni combos)
