I believe the blue alliance in qualification 24 of Northern Lights just achieved Triple Tortuga!

post video, get starbucks!

I know it seems mean, but I can't wait. Someone please post a link. In the mean time, any details you can tell? The first one came out of the blue, how did this one unfold?

Do tell...

I do not have video of the match, nor can I find an archive of it. I have been watching from home on a low quality, lagging stream, (my home internet connection is very slow). For this reason congrats to whoever has video of the match. This is what I remember seeing.

I do not remember which robot was which, so I will refer to the blue alliance robots as: blue 1, blue 2, and blue 3.

Blue 1 was stuck in the moat, so blue 2 tried to help them out. Blue 2 was able to push blue 1 off the moat, but in doing so blue 1 flipped, blocking the mid-field entrance/exit of the moat. Meanwhile blue 2 got stuck in the moat where blue 1 had been. Blue 3 appeared to not be moving, and was positioned it front of the low bar. They appeared to be more dead/disabled than stuck.

This is what I remember seeing, and is likely not a perfect account of what happened, but I am looking forward to seeing a video of it to see what actually happened. It could have very easily not been a triple, but instead a double if blue 3 happened to move again, or if blue 2 had freed themselves from the moat. (The webcast finished the final seconds of the match focused on the red robots surrounding/climbing the tower, so I was not able to see a definitive shot of a triple tortuga.)

Waterbury - I'm not sure it was a triple, but of interest: a match (somewhere in the 30s), one robot flipped over in the courtyard, one stuck on the moat, the third on top of the second robot. Yep. My team was on top of the other robot.

Our "Tortuga" song hasn't been played yet at Waterbury, but with the help of mooretep, I think you all would enjoy.

Re: The Triple Tortuga is Contest born.
 

It finally got played. I forget which match. Only a lone Tortuga.

Hope mohave more tomorrow as there are several candidates with a high C.O.G.

Alright, since I was wondering the likelihood of all your gift cards being claimed and since doing FRC-related statistical analysis is basically what I do for fun, I decided to crunch some numbers over it. After a lot of math, this is what I found:

In order for it to be more likely than not that all 5 of your Tortuga prizes are claimed, the mean probability of a robot getting stuck in any given match needs to be at least ~6.3% (i.e. the average robot would have to get stuck at least once every 16ish matches).*

From my prior knowledge in FRC, I would say this number is conservative enough that all 5 of your prizes will almost certainly be taken by the end of the season.

*To calculate this figure I assumed 127 competitions with 75 qual matches each on average (I eyeballed this average from TBA event pages). Also, this model relies on some tenuous assumptions about the distribution of likeliness to tortuga so, uh, don't use it to place any bets.

Re: The Triple Tortuga is Contest born.
 

Is that implying all Tortugas are caught on video right away?

Re: The Triple Tortuga is Contest born.
 

Yes.

Re: The Triple Tortuga is Contest born.
 

I believe your calculations assume that tortugas are independent events. I think it highly likely that double and triple tortugas will be more common than the number of singles would indicate. The 3T from Palmetto is a great example of why this would be the case - none of those robots would have been a single tortuga. Only by interacting did the robots become immobile. The double tortuga reported by Hitchhiker 42 sounds like a bit of a cascade as well.

Like this?

Re: The Triple Tortuga is Contest born.
 

That's impressive.

Re: The Triple Tortuga is Contest born.
 

It's amazing how such low robots are able to get tipped over.

Re: The Triple Tortuga is Contest born.
 

With the speeds of crossings and how high these robots jump, I am surprised it is not more common. Our robot flipped in one match at Mount Olive because we went full speed then reversed the wheels while in the air. DOH! We will endeavor not to do that again.
