But still in sense of the the term "Full Court Shooter" that everyone is this thread is implying is a shooter that won't be blocked by a 60" robot and can stay in the corner indefinitely if needed until they want to climb.

Our robot shoots from 60"..unless we are facing an 84" tall robot..no one will be blocking our shots...(I speculate this)
We have the ability to shoot from the autoline, the half courtlline and pyramid as well as floor load (maybe). So in my opinion a 60" tall full court shooter is 100x more effective.

Its not a forced penalty. The full court shooter is playing the game and the defender is impeding the flow and would get the penalty.

No it wouldn't. Its just like last year. If you are close enough to get touched by a robot in a loading zone or touching their pyramid and you get touched, while they are still touching said locations, you will get a penalty not the robot in the safe areas .

Here are some numbers to toss around:

--assuming the full court shooter is approximately 52 ft away from the high goal.--

-A robot shooting from 30" off the ground can be blocked by a 60" tall robot standing ~7ft or closer.
-A robot shooting from 30" off the ground can be blocked by a 84" tall robot standing ~13ft or closer.
-A robot shooting from 60" off the ground CANNOT be blocked by another robot that is 60" tall.
-A robot shooting from 60" off the ground can be blocked by a robot 84" tall standing ~5ft or closer.

*This is assuming none of the shooting robots have exceptionally high arcing shot trajectories.

Basically, 30" high full court shooters will have to be opportunistic while 60" high shooters will be able to shoot all 45 disks regardless of defense so long as a partners agrees to sit in front of them.

3. Where are you getting 40% is 18 discs?


3) 40% x 45 white disc = 18

2) Absolutely true; if there are no discs on the floor (i.e. discs are not being shot from the feeder station), the floor feeder is absolutely useless.

1) It would be ALOT easier to defend a robot trying to leave the feeder station (and transverse the field) than it would be against a cross-court shooter who has no plans of leaving. As BJC has put it, a 60" feeder-bot would be blocked by an 84" defender 4' away. That is far enough away to avoid the auto-zone penalty but close enough to still block shots (very hard shots mind you).

In that case, one possible solution is to use your 3rd teammate as a buffer for your cross-court shooter; to keep the opposing defender out of the parabolic path of the discs.

Is the system perfect? No; none is. But it's WAY more efficient than any other.

You do realize that each alliance has way more than 45 white discs.

??? No they don't. Each alliance starts with 45 white discs and 6 red or blue discs divided among the HP's how the alliance sees fit.

Ummm... 3.1.1.C&D
6 Red & 45 White DISCS are located in the Red ALLIANCE STATION.
6 Blue & 45 White DISCS are located in the Blue ALLIANCE STATION.

Unless I'm reading this wrong...

Oh, I thought the rules said each alliance got 118 discs. My bad.

118 is the total number of discs.

If each alliance had 118 discs the rules would allow us to carry more than 4 at a time.

It sounds contradictory in terms of what is easier to defend.
If you can successfully park your robot and block feeder station shots, how is that not easier to defend?

You're right in the qualification matches, but in my experience, no one plays defense in qualifications. You'd be lucky to run into a team that is humble enough to play defense instead of offense. However, I think it becomes very evident to those higher ranked teams in eliminations that if there is a cross court shooter, then immediately following autonomous, it becomes priority to stop that shooter. You'll likely see alliance picks and defensive strategies geared to stop that shooter. I think it will be likely that your cross court shooter bot might have some heavy pressure placed on it in the match, which will make you miss some shots, even if you are 60" tall. Don't forget that humans are intimidated by pressure.

Also defensive robots have the quicker trip to your protected feeder station than you do. If they can get in your way and slow you down or stop you from getting into position you have become useless.

I can see how my statement may have been clear. Let me word it differently.
Any robot with wheels and a passable driver can play defense on a robot trying to transverse the field. ONLY a robot 84"(or so) tall within a certain distance can play effective defense on a park-and-shoot.

AND... if push comes to shove, all the park-and-shoot needs to do to overcome the defender 4 feet away is to pull away from the wall (like they are going to leave the feeder station), turn to their right, and fade back to the opposing teams driver station to distance themselves from the defender and make their shots. Then load up and repeat.

This routine should take mere seconds and should still allow you to to empty 36-40 of the feeder station discs. Meaning the 84" bot would have to jockey for blocking position.

Of course you could always go the easy route and just have your robot #3 play D for your cross-court shooter.

How are you calculating this number?
A relatively flat shot will rise 54" (114"-60") over ~50 feet. Which gives a slope of ~1 inch of rise per foot of travel. That would require 24 feet of space(almost half of the field!) before a frisbee would clear a 84" tall robot.

That's not how Frisbees Fly. You can get them to altitude quickly and they naturally level off and travel relatively flat for quite a distance.

Also, many of you are not taking into consideration Frisbee curve and the defensive robot's own tower. A tall defensive robot can get blocked by its own tower if a cross court shooter has dialed in their trajectory.
