Re: Questions Regarding Defense
 
From QA today. If the robot being defending has a camera or some type of targeting sensor, you could be penalized under R9-C.

Question
Game Manual - Robot » Safety & Damage Prevention
Q953 Q. I understand that you cannot determine whether or not a device is legal sight unseen. I am asking this question because an LRI said it would be a violation of R9-C if we had a piece of lexan on our robot standing vertically to prevent a camera from seeing the reflective tape on the goals. I see no difference between having a sheet of lexan standing 48" and a robot standing 48". Please clarify what is meant by "interfering with remote sensing capabilities" in R9-C

A. A piece of plastic installed to prevent a camera from seeing the reflective tape on the goals is a device specifically designed or intended to interfere with another ROBOT'S sensing capabilities and is prohibited by R9 and the added language included in its Blue Box.

I believe it's technically possible to block the high goal outside of the last 20 seconds by having a "jumping" mechanism. Your robot could jump into the high goal, thus blocking it.

G12-D,F,G might stump you there.

An alternative strategy:
If your team is capable of capturing the tower, then focus on preventing the opponent from capturing. Focus on the 2nd robot that is scoring and stop them. I have yet to see a robot that can score 8 boulders from the outerworks by itself (but I hope to!). And grab any missed boulders and shove them into the secret passage so they have to cross the OW to get more.

Is shooting from the outer works legal? In other words, would shots from the outer works still count?

Er, yes? Why would it not be?

Here is the Q and A about it

Quote:
Q. "A robot carrying a boulder crosses a defense into their opponents' courtyard. They then move back such that a part of its bumpers are within the opponent’s outer works while their robot is still in contact with the courtyard carpet. They attempt to line up a shot, but an opponent contacts them. Does the opponent incur a G43 penalty?"
2016-01-14 by FRC3322
A. This situation does demonstrate a violation of G43. Per G43: "A ROBOT is considered traversing the opponent’s OUTER WORKS if any part of its BUMPERS are within the opponent’s OUTER WORKS." Even if you are shooting a BOULDER, you would be protected by G43 if your BUMPERS are within the OUTER WORKS.

Re: Questions Regarding Defense
 
Another great way to play defense, besides just blocking their shots, is to bump the shooter around a bit. Just watch Semifinals 2 and 4 from the 2016 Midland District. Our alliance partner, 5222, would wait for the opponents to begin lining up for their shots and then bump them just enough to mess with their line of fire. This made it almost impossible for the others to make a shot.

We hit 8 boulders from the outworks at least once, and maybe twice at CVR. I think you'll see more of that in the next 3 weeks.

Re: Questions Regarding Defense
 
So in general (sorry to change subject) defense, could you have a robot that reaches over the top of another robot? Like for example have like an arm that extends out so when the ball is fired it stops it from even truly leaving the other robot's frame perimeter.
