G<aggressive play>

Overly Aggressive Play is loosely defined as actions beyond strong defensive pushing and blocking interaction. Strategies aimed solely at the destruction, damage, tipping, or entanglement of robots are not allowed. Accidental tipping is allowed at the discretion of the head referees.
Head referees (with help of other refs judgement) have the right to issue yellow warning cards to any team deemed to have crossed the boundaries of aggressive play at any point in a match. These cards will be carried and tracked throughout the entire competition, including all qualification and elimination/final rounds. A team may receive a maximum of 3 yellow cards. Any warning beyond the 3rd will be a Red/DQ card for each additional occurrence of overly aggressive play.
Teams are encouraged to build their robots robust, using common sense meaning of the word and taking into account game objectives and possible strategies.

I borrowed the yellow card idea because I think it's a great suggestion. It gives a tangible and visible warning to the teams who border on overly aggressive play. It also allows the referees some room to warn without having to immediately make the huge decision of DQing a team for questionable actions.

I feel the yellow cards should be carried throughout the entire event because if you only apply it to 2 or 3 consecutive matches, it gives more opportunities to take advantage of aggressive play. Since we didn't see many calls or blatant aggressive situations this season, I don't see any problem in having the warnings apply to an entire event - it shouldn't become a huge issue. I think it would be sufficient to give a set limitation of warnings. Plus it would be easier to track - 3 yellow is all you get.

I also included parts of the existing rule because I think it's worded well and makes the point of disallowing intentional "battlebot" behavior. And although I think it's unnecessary, I included a statement about "robustness", but it should be simply common sense.
Although "intention" will always be a tough judgement, this would give teams the notice that other people are seeing driving habits on the verge of unacceptable. If they want to discuss it with the ref, that's fine, but at least they weren't DQ'd on the spot, which is worse than a warning. I feel the warning is enough without any "enalty shutdown periods".

Strong defense should be expected to be part of the game and there are plenty of ways to play it without becoming overly aggressive.
