Car Nack Predicts 12-1

[Nathan Streeter]

Assuming Car Nack meant that a single alliance will never score more than 36 points in auto, I would say he's likely going to be wrong, but very rarely!

Given that we could have some robots feeding into a great scorer, a robot getting the balls from one or both of their available ramps, etc. I think this'll happen on a few occasions throughout the competition season... it'll be attempted many, many more times!

I'm seeing a lot of bots that collect on the opposite side of their shooter. With a second bot that tips the bridge from the side, these balls roll straight into a center key shooter rear collector if they keep it running in autonomous (please do this if you're competing in Florida!). I think 36 is very possible.

Technically, Car Nack wins. Our alliance at Kettering (862, 3322, 3601) scored 6 balls in the top hoop in autonomous, but the last score was counted in teleop. I will post video as soon as I can find some... we had a Rube Goldberg autonomous setup.

I hope someone caught it on camera! Sounds pretty interesting.

Came here to say this. It was seriously awesome.

This was done with Team 3322 (a consistent, very very strong shooter), Team 862 (a shooter) and team 3601 (a feeder bot with an open top) by lining the three up very close to each other, with 3322 being at the key.

KEY
3322
3601 862

They were all touching each other. When autonomous begins our robot shoots its two balls (which it has never missed as far as I'm aware,) then 3601 passes its two balls to us through the feeder by reversing the feeder motor (something I believe was already a part of their design, they simply modified their autonomous to do it.) As its doings this, 862 shoots at a very low RPM their balls into 3601's open-topped ball holder. The motors still turning, it sends the balls to us as we have already shot the first two 3601 gave us. We then shoot the two 3601 passed to us.

I don't believe we ever got less than four, except for during one field error which we re-played and I believe that was the match in which we got all six (technically.) Our average was about five. The reason we didn't get six every time was simply due to the variables: the way the balls that 862 shot to 3601 bounced before getting sucked down into the feeder, a ball which just barely bounced off the rim (almost unheard of for our autonomous until we tried shooting so many balls.)

It was really great.

Doesn't really show how it works though...

The 3322-3601-862 maneuver was honestly one of the coolest things I have ever seen in FRC. I am seriously impressed you guys put that together, had it soo successful, had it so repeatable, in Week1! That deserved a creativity award in my book. It was one of those moves that people talk about, but it was truly amazing you guys did it.

[Joe J.]

This was team work at its finest, that strategy was all student thought up and implemented.

It was amazing watching all three teams work this out on the practice field, deploying the final code in queuing right before our match and to have it work so consistently.

[Steven Donow]

Wow, that passing maneuver is seriously just too cool.

[Nathan Streeter]

Wow, sounds truly awesome! Yeah, definitely the kind of play teams talk about often, but that I've rarely seen implemented... Congratulations, guys!

(Just to confirm, you never ended up getting all 6 in during hybrid... to get 36 auto points?)

All six balls passed the rim before the buzzer, but the 6th ball didn't pass the sensor (how the FMS scores a match) before the buzzer.

We got 33 in the third final match. We shot the sixth ball in auton and it went in the top basket, but by the time it passed through the ball counter it was the teleop period.

Here's a video of us testing the autonomous code during lunch (we didn't get to test the slight modification which put us within the time limit, but we made 862 fire two seconds quicker): http://www.youtube.com/watch?v=zo-SUmQRjRM

Although I'm not quite ready to say Car Nack I wrong, I think most teams should do fairly well in hybrid, potentialy beter than in teleop. The conditions are similar to all those team youtube demos we saw, were robots seamingly always made three pointers. No defense, balls already loaded, repeatable position. In teleop (where I at least was underwhelmed by shooter preformance), you need autoaim to score consistantly, which most teams can't use. Hybrid performance doesn't need as sophisticated software.
