One question... do you plan anything (i.e. a push down friction pad?) that prevents being spun like a top by a defender, or is that not a concern?

It's not a concern primarily because a defender ought not be wasting their time with us and an offensive machine's time is better spent trying to score (or outscore, as it were) our robot than to get in its way. We can switch between one or two pairs of omniwheels in about a minute, so we have some flexibility in determining how we want the robot to perform.

Are you speaking of the fenders at each of the four corners? If need be, I can mill those to be a vertically oriented 'wedge' that will help to stop other machines from getting caught on or in the channel.

Thanks! I posted an annotated rendering of the mecanum drive base that we built in the off-season, but I don't think I've posted any other images of this particular drivetrain. In any case, the overall dimensions are a slim 27" x 36" -- while the wheelbase is approximately 24" wide and 28" long.

Nope -- it's not a legal COTS component, and it's heavy and ugly. It just happened to be a convenient platform for support the battery while testing.

Especially considering you're still using a drive-train designed for precision turning, and are in the 5', 110 lb. weight division.

As I mentioned above -- we can easily switch a pair of omniwheels for something that has more traction -- so this is a very versatile design. Defense will be important in this game given how imbalanced the effort to score is as compared to what it'll likely take to prevent someone from scoring, so I geared for a slight pushing advantage over most teams. We're making no effort at pushing those with drivetrains designed expressly as tanks because we don't see those types of robots spending much time hassling us.
