Go to Post If you don't have anything nice to say, don't say it all. I mean, I know we all get frustrated during build season, but we still need to make an effort to be polite and helpful. - Karthik [more]

There has been no limitation on keeping robots away from the trackballs.

Quotes from the Q&A which show the GDC has reiterated this:
  • FIRST Overdrive has never been defined as an "all-offense, no-defense game." Defensive strategies, used appropriately, are perfectly acceptable.
  • A Robot, and any Trackball in the possession of that Robot, only receives protection from interference while it is in the process of Hurdling (as specified in Rule <G42>). Neither the Robot nor the Trackball receive any special protection at any other time.
  • There is no rule that would prohibit the blocking robot's action. There are also no rules that would prohibit an appropriate counter measure by your robot. This scenario would likely become a pushing match.
Very good post. I agree that many teams are scared to play defense due to some of these rules or don't think robot to robot defensive interaction is allowed/approved.

There are no rules that say you can't push a team (using bumper to bumper interaction), preventing them from going around the track outside of thier zone. This is one aspect that would be very effective at stopping a hurdler. Instead of trying to hit the bouncing ball away from a hurdler, why not push the hurdler (a much more predictable movement and usually slower and larger than the ball and thus an easier target)? Or once they have the ball, push them against the wall for 5 seconds? I think teams are trying to get too cute with defense and comming up clever 'ball defense' instead of playing effective defense from the past two years, pushing the opponents robot.
