After worlds. Across the season I believe. I'm not exactly sure what part of the portcullis during putting it together/taking it apart gave volunteers injuries.
It tried to take fingers off. really. Some of the injuries were severe.

...
Nice adjustments, as usual. So, if a robot goes the wrong way out of auton, G13 applies as it did during the season?


The G13 modification does not mention the award of a crossing to the robot contacted. In the event that a robot attempting a two-boulder auton contacts an opponent's robot which has become stuck in the outer works on its initial attempt to cross, do you intend to retain or remove the crossing award portion of the penalty from the rule?

Large constant force springs are dangerous... They're pretty much spring steel knives that are also tensioned and capable of rapid movement w/ reasonable force.

Very easy to hurt yourself if you're not knowledgeable and careful.

I'll concur. We had a large CF spring on our elevator in 2015. It was always a tense moment attaching it to the carriage, making sure only the people needed during the installation were the ones near the robot at the time. Injuries would not surprise me at all.

FIRST discontinued the portcullis due to safety. It apparently gave a number of volunteers injuries and sent a couple to the hospital. (while putting it together/and taking it down, field reset volunteers didn't get injured but it was the volunteers who made sure it was ready/volunteers that needed to take it apart I think)
One of the field supervisors recently posted a rather graphic) picture of his rather damaged fingers due to the portcullis mangling it (he needed screws placed int his broken fingers). We don't need any more injuries.

We are working on a listing to capture the scenarios we can think of and how they would be decided. Hopefully not needed, but we want to have it defined in advance.
That's exactly how I interpreted the rule. I don't think you need to spend too much time calculating all the possibilities. Something simple like, "If teams get a tie score in 3 matches in an elimination round, the tie-breaker rules will apply to subsequent matches for those 2 teams in that round."

Is IRI planning on continuing the patch's that go on the standards? For that matter, does any other off season event plan on making any?

It would be pretty awesome if their was an IRI sticker that teams could put on! It was a cool aspect of this years game.

If the robot goes the wrong way initially, the rule still applies.

If there is contact after a robot has crossed a defense and come back, there is no crossing award.

We don't give away all of our surprises :D

(there could be one in the works ...)

Yeah, my point was more along the lines of "better", not "perfect". Obviously I wasn't clear enough... To be fair the play style was somewhat unique in IN (compared to other areas) which may explain our lack of panel breakage.

We did break a couple batter dividers though (1 in Indiana, 1 on Carson) and had various light string short-outs (which I'm not going to comment on further), so it wasn't field repair utopia. You can't win them all...
That one batter divider in Indiana was because of our team. After the match, a volunteer gave us the broken pieces and we have them in our shop. ;)

Yeah... we snapped a panel in half at the Hartford Regional this year, doesnt take much to snap it when you have a 6cim 3:1 drive, haha.

If they are using the CDF setup that we had to add on to ours at Arizona West in Week 6, I want to meet the robot that can break them without breaking the base. It was a steel plate added along the full length of the bottom of the panel. I just barely missed dropping them on my feet when I *tried* to pick up the box when I didn't know what was inside and was opening my FTA presents from HQ. I still can't believe that FedEx actually shipped them in one box, they were so heavy.

I got lucky this year. Four events with zero CDF/Portcullis breakage as far as I know. One drawbridge panel that didn't look so healthy, but was fine for practice field use.

Will the boulders at IRI be used, new, or a combination of both?
