Defensive Strategies

[KingBK]

I really don't see a way to stop the other team from scoring on you. You could be able to put a lid on your trailer if you still fit in the dimensions but that is all your robot would really be able to do. I really think the best defense is going to be a good offense. Controlling the balls and making sure that you make them in the other alliances trailer before they make them in yours.

What if you just backed yourself into a corner of the arena and used your robot to block your goal? That could be useful end-game to prevent being supercelled by the other alliance.

not a bad idea but there is no real corner.

Depends on how good the human players were. 1073 won a playoff match in 2004 when the human player threw a playground ball into the goal from clear across the field at the last second.

But I agree, this is not a bad endgame strategy if you have no other defensive options (i.e. no lid, etc).

e: you do have to keep in mind that there is a red payload specialist on the side of the field and vice versa...there is no location for the robot to be that is more than 20 feet away from a human player...

What makes you say that?

I would personally say that the fact that a "moon rock" is put in at the beginning is a great advantage for the end of the match when there is less room for a "super cell".

as of now, and i hope moving forward, that is inncorrect information, unless you can show a rule that spicificly states this situation

<G07> B. If a TRAILER tips over, the points SCORED for that TRAILER at the time it was tipped will be preserved for the remainder of the MATCH.

your comparing apples to oranges. totally different situations.

I was thinking about this for a while


how about using air cannons to deflect cells?
How much would it take to actually have an effecton an incoming cell?
Most likely there wouldnt be enough pressure and volume for there to have an effect on an orbitball.


however i dont think it has been tried

Apologies for the incorrect information, however if you are allowed to descore, then, I would assume descoring from allies is also allowed. If from yourself, then why not your teammates? This would a low a single robot on you team to be designated a "descorer" perhaps with a conveyor-hook settup to simply go up to allies and remove balls through the grates of their trailers. This seems to be against the spirit of the competition, leading to my previous point.

I still believe that it is not a good idea however, as I mentioned before, one moon rock in at the beginning means less room for a super cell to be tossed in during the last 20 seconds.

But as soon as you start restricting its motion from the inside, I'd call that some form of attaching to.


Realistically, I think this will end up in Q&A very quickly. I would expect that the answer would be something to the effect of "As long as no rules on contact outside the bumper zone are violated, it's fine."

Which then means that all one robot has to do to get you in trouble is tangle you up. If it's done enough, you have to modify your design.

Firstly, vaguely restricting the motion of an object isn't "attaching" to it. Apply that definition to robots, and pinning a robot would suddenly count as attaching to it. It's more on the lines of entanglement, which is judged case-by-case, and you have to actually end up caught up with the trailer.

Secondly, if the GDC restricts this by the contact outside the bumper zone rule, it simply makes it slightly more tricky. Remember that you're descoring on a trailer attached to one of your partners. They have a vested interest in not screwing you up. Also remember that a robot can not be forced into a penalty by an opposing robot. If an opponent is trying to stop you from descoring and this causes you to violate a rule, you shouldn't be penalized.
