<SG3> Stay on your side in Autonomous. During the Autonomous Period, Robots may not do any
of the following:
Contact the foam tiles on the opposing Alliance’s side of the Autonomous Line.
Contact the opposing Alliance Platform.
Become Center Parked.
Violations of this rule will result in the Autonomous Bonus being awarded to the opposing Alliance.
Intentional, strategic, or egregious violations, such as intentional contact with an opposing Robot
while completely across the Autonomous Line, will result in a Disqualification
In SG3, the first two lines are clearly saying what your robot is not allowed to do, not what it's impossible for your robot to do, so I assume the third line is the same way: the robot is not allowed to become center parked.
I assume that means the robot is not allowed to be in a position where it would normally count as center parked, although it seems the robot is technically allowed to be mostly on top of the center platform, as long as it doesn't meet the criteria for being center parked.
Center Parked – A Robot status. A Robot is Center Parked when it is:
o Contacting the Center Platform.
o Not contacting any Alliance Platform.
o Not contacting the foam field tiles or white tape.
(Rules are quoted from @536Mentor and @Gear Geeks, respectively.)
Edit: It would definitely be good to check in the Q&A, too, so we can be sure, and so there can be documentation of the correct interpretation.
