What is so ridiculous? FIRST made a rule, don't go into the corner goal. They listened last year and said we'll spot you ~3 inches.

What would you have them do better?

The scoring system this year is real-time. Once points for robots on platforms are added and any penalties are given, the score is ready to be displayed.

The scoring in the lower goals is counted by a camera (of course with a human back-up in case a robot goes into the goal). There are lights under the goal, with a camera mounted at the top of the player's station. A wire mesh is mounted inside the goal to keep the HP's from reaching over the light (one swipe of a hand across the light and the camera counts 5-7 balls). The 2-3 inch margin teams are given for going into the goals is the space from the outer edge of the goal, to where the camera begins scoring. Anything that crosses that light can be scored by the camera, including a robot.

FIRST designed a system which allows you 3 inches of space, so follow it. Almost every team at VCU didn't have a problem with it, why should it be changed to help the few that don't follow the rules? This isn't by any measure a new rule. It's been in place for the entire season, you should plan accordingly. In 2004 there were similar rules, that didn't even give those 3 inches.

I don't really think it's a minefield...the only DQ's ive seen so far have been from incursions into the corner goals. The rule has been in place since day 1, so it should be no surprise to teams. I know a number of dumper-bots developed guards to keep them from getting pushed in.

All i'm saying is that they should strive to make disqualifications as rare as possible, since they really make the game less spectatorish. What they could have done differently is design the scoring mechanism so that it can't be thrown out of whack by a robot accidentally sticking something in there 3 inches.

Just my 2 cents.

Personally, i think Triple Play had much more chances for DQ/penaltys than this years game. Who doesnet remember the plexi triangles we had to TOUCH to be able to pickup tetras?

I Saw only one DQ and a small handful of pentalties for the 3 hours i watched on saturday, thats hardly a "Minefield"!

As far as I know, there were about two teams at VCU that kept being disqualified. Once you see how far those robots went into that goal, you would see how and why they were disqualified. The cameras are extra sensitive. They could pick up anything that passes through the corner goals.

On this note, if anyone has noticed a few extremely high scores posted in the results of the first week regionals. The one case that stands out to me is a score of 11109 at VCU, but if that were a typing error of a score of 109, there were also scores of aver 200, which I find hard to believe given the other scores we saw, even in the finals. I believe that the reason for these errant scores may be robot incursion into the corner goals. I believe that if a robot enters the goal, it will be counted as much more than a simple hand, and thus even a short infraction would greatly inflate scores. This would make FIRST's position on DQing any violators very reasonable, as it would be a major hassle to figure out the right score, and it may not be possible. Thus they are trying to make it as fair for everyone as possible, so that there is no dispute over scores. This is the most equitable process for dealing with this inherent shortcoming in the ball counting technology, and as they clearly published the penalties for goal infraction, it is by no means unfair to DQ any team found in violation of this, especially in light of the problems that it causes in scoring the matches.

At NJ we actually had a team that accidently waved their hand in front of the camera when they were getting the ball and that resulted in points for their opponents, and incidentally cost them the match.

In Match 75, did 1610 get DQ'd?? It's they only way to explain why first lists them as 6-2-0 instead of 7-1-0.

They may have been dq'd there. I saw a few matche were teams should have been dq'd and weren't. Not only in VCU but in NJ also.
Example:
In match 75 @ VCU when 1137 hit 623 in the side, continued to drive, and eventually flipped 623.

edit:
post's orginal intent was same, but I thought soap108's post meant they didn't get DQ'ed

Yes, they were disqualified. They may have been ranked #1 if they had not been disqualified. Anyway, that disqualification didn't hurt them at all considering that they won the regional. ;)

Thanks. I caught it in the video- it looks like the ref raises her arm to signal that they invaded the 1pt scoring zone.

I have noted the following Qualification DQs:
match 32 - team 1093
match 63 - team 1467
match 69 - team 587
match 72 - team 1184
match 75 - team 1610

Its kinda interesting that most happened on Saturday.

After spending Thursday, Friday, and Saturday standing beside one of the corner goals at VCU I've been wondering how the 3 inch rule is interpreted. The bumpers extend 3-1/2 inches beyond the frame of the robot and end 8-1/2 inches above the floor. The opening of the corner goal is 10 inches high so the bumpers will extend into the goal when the frame of the robot is against the polycarbonate. If the goal starts at the field side of the polycarbonate, the bumpers are 3-1/2 inches into the goal. If the goal starts at the corral side of the polycarbonate then the bumpers extend 3-1/8 inches into the goal.

I could flex the center of the polycarbonate about 3/4 inch with my fingers, so a hit by the corner of a robot would flex it even more. It seems to me that a legal bumper system could easily draw a penalty.

Any refs out there who could tell me how the 3 inches is determined during game play?

Greg
