That's an incredible robot. It looks like to defend against it you must:

A. Block the tunnel in autonomous, just long enough to get any balls scored out of the ball return. (And incidentally, do they have a way to stop themselves from going over the center line and incurring a penalty if they glance off of an opposing robot during autonomous?)

B. Clear their zone of balls very, very quickly. (This will require a good defensive bot with the ability to kick balls, preferably two zones).

If you can manage those two things, and then play relatively typical ball denial in the middle zone for the rest of the game, you should be able to pull off a win.

If you can't...
