G12 Update clarification

[RRLedford]

This still does not clarify whether positioning lower goal blocking robot extensions sufficiently across (but outside) their faces, and then leaving them statically positioned while an opponent tries to score the ball past them, would be considered a defensive trapping violation.

If the defensive blocker remains static, the ball's contact with their defensive elements is 100% initiated by the offense bot's pushing of the ball, so IMO it should not be a trapping foul.

If it is not a foul, then many bots will be able to easily prevent any balls being scored at a lower goal with minimum deployment(s) of lower goal blocking elements. It will also raise another concern for when a goal blocking element might be deformed by the ball pushing against it to point of passing inside the plane of the goal face. Since the offensive bot would be causing it to happen, it should not be a foul, but what if ball then gets wedged against inside of goal, against a deformed blocking element such that ball cannot pass further inward or be pull back outward.

That would put scoring on permanent hold for the offensive team, yet it would seem they caused their own demise by trying to force the ball past the goal blocking element. Yet the defender may have intentionally designed their blocking elements to specifically cause this kind of a result.

I feel this is completely legal. The tradeoff is not being able to block both low goals at once (unless you have 2 robots doing this....) and without proper design, the ball will almost instantly go into the low goal the second the defensive mechanism is retracted if the ball is stuck upon the mechanism.

My question is, if the ball is on your mechanism or you attempt to move with an opponent's ball stuck in between your defensive extension and the wall and the ball travels with you, is it possession?

(Emphasis Mine)

I think in the situation you described here, the defending team has caused the ball to be stuck in the goal. This would not be the fault of the offensive team, they are just trying to score. If I were a ref(which I'm not), I would probably call trapping here. The ball is "trapped" inside the goal, and this situation is being caused by the defensive team. Additionally, if the defender is unable to pull free, they could be subject to an additional technical foul and/or red card.

The easiest way to determine possession is if that drive team changed directions to impact the ball. Or went OUT OF HIS WAY to get to the ball.
Strategically speaking a team might not be fouled for a possession once, but this is not the only time they are seeing you. You should get a good idea of what the robot will be capable of doing by the second match. So if the refs think this is the second time they have seen that same idea it might turn on some ideas.
