2565: Forcing a DQ through SG6, G15, and diagonal corner guarding


15797A
23-Feb-2025

At our state championship, the head referee decided that when a robot is guarding a Mobile Goal placed in a corner while possessing another Mobile Goal, another team could push them into the goal they were guarding, and the defensive (guarding) team would automatically receive an <SG6> violation. Below is a diagram of how this could happen, with the red alliance defending the goals and the blue alliance pushing them into the corner:

However, most of us at the competition thought that this ruling was in direct contradiction with <G15>, which states:

You can't force an opponent into a penalty. Intentional strategies that cause an opponent to break a rule are not permitted, and will not result in a Violation for the opposing alliance.

During the competition, teams were able to ram a bot guarding a corner while possessing a goal into the corner (in the scenario described above), giving the guarding team and instant <SG6> violation and giving the alliance an instantaneous 2 win points. The referee's logic for this decision was that by guarding the positive corner while possessing a Mobile Goal, the guarding team was forcing any team that wanted to contest the corner into a <G15> violation, and consequentially, the <G15> violations "canceled out." They also stated that the guarding team should be able to move out of the way or drop their goal to avoid a disqualification, but this logic doesn't make sense, because it forces the guarding team to either give up a mobile goal or give up the positive corner to avoid a disqualification.

This leads us to our main question:

  • Does guarding a Mobile Goal placed in a positive corner while possessing another goal void you from <G15> protections? (i.e, should a team be able to force you into a Disqualification if you are guarding a corner in the scenario described in this post?)

We'll start by reminding you that Head Referees' ruling are final, and that we cannot and will not overturn them. However, should similar scenarios come up at future events, the following guidance applies.

...the head referee decided that when a robot is guarding a Mobile Goal placed in a corner while possessing another Mobile Goal, another team could push them into the goal they were guarding, and the defensive (guarding) team would automatically receive an SG6 violation.

To violate <SG6> in this scenario, the red Robot would have to Plow or Possess that second Mobile Goal in the Corner. Contact alone does not warrant a violation. As described in our answer to Q&A 2304, minor, incidental contact with a Mobile Goal likely wouldn't be considered Plowing. Unless the actions of the blue Robot are forcing the red Robot to Plow or Possess the second Mobile Goal that's in the Corner, there is no <SG6> violation being forced upon the red Robot. If the red Robot is indeed forced into Plowing or Possessing a second Mobile Goal by the blue Robot, the <SG6> Violation simply wouldn't be enforced on the red Robot in accordance with <G15>.

The referee's logic for this decision was that by guarding the positive corner while possessing a Mobile Goal, the guarding team was forcing any team that wanted to contest the corner into a G15 violation...

It is perfectly legal for the red Robot to defend a Mobile Goal in the Corner while Possessing a different Mobile Goal, as stated in Q&A 2013. More importantly, this action alone cannot be a <G15> Violation. The red Robot defending the Corner is not forcing the blue Robot into doing anything in this scenario. In an effort to gain access to the Mobile Goal in the Corner, the blue Robot is choosing to drive into the red Robot and push it into contact with the Mobile Goal in the Corner. The blue Robot might be incentivized to make a play for the Mobile Goal in the Corner, but that doesn't mean the blue Robot is forced to go along with that play. That is a critical distinction that must be made in regards to <G15>.
