Only one problem with whizzing around those "slow" six wheelers. If they get between you and your objective(s), one "slow" robot, driven right, can block a mecanum. We actually tested this out, and it was one reason we chose not to use mecanum this year. Our mecanum Kitbot could not get around or through our '03 bot by any means, and '03 is not easy to steer (though we didn't need to to block Kitbot). Also, you need your CG pretty well centered, or your robot will not get the full mecanum effect. Moral of the story: TEST FIRST! It could save you a lot of pushing and other fun stuff at competition.
