Thank you Team 1756 for the assist and Team 4028 for being so trusting. We couldn't have done it without you.
No really, we couldn't have :D
That is truly a splendid thing. Did 1756 go up first, and is there a place where we might see video?
I'm pretty sure that's our teams bumper sticking up in the bottom of the picture. We tipped two of our alliance's robots over (including our own) by trying to triple balance. We'll have to work on that for Milwaukee. Congratulations guys on winning Boilermaker!

The sequence of events;
1) Team 1756 goes on to the bridge first followed closely by Team 4028. We continue shooting and scoring :rolleyes:
2) The two on the bridge tip the bridge away from us.
3) We pull under the lip of the bridge while they tip the bridge back on top of our Fantail.
4) Team 4028 drives onto our Flight Deck.
5) We back away with 4028 on top of us. We only loose contact with the bridge once.
6) Team 1756 tips the bridge towards us and we climb on behind them. All the time 4028 is driving toward our tower to keep them in place in case we over balance the bridge.
7) BALANCE 3!!!
Easy peasy lemom squeasy :D

You can see those pictures on Flickr under "2012 - Boilermaker Regional"
Doesn't the G30-1 rule have an issue with this sequence? It's the "lose contact once" part that might be problematic. Another rule added after kickoff...
[G30-1]
A Robot may only be supported (fully or partially) by another Robot if one of the Robots is in contact with a Bridge.
Violation: Technical Foul for extended, strategic, or repeated loss of contact.

Fembots were so close.
Congrats!

Great work 1501! We were watching the elimination rounds while building our new bridge device. Couldn't believe you actually got the 3 robots on like that :) We saw you on the practice field in Smoky Mountains balancing but it never happened on the field unfortunately :(.
Great too see the potential from these Landing Pad robots. You were the one alliance i was scared of in Smoky Mountains. Great to see you came out with a victory though :)
The head refs were told that momentary loss of contact with the bridge was consistent with the spirit of the rule and was OK.
That is truly a splendid thing. Did 1756 go up first, and is there a place where we might see video?
1756 pushed the bridge down with 4028 following them up. Both would tip the bridge down towards the alley, where we would then place our "flight deck" under the lip of bridge so that once the bridge would tip down towards us, we would catch the bridge and keep it level. 4028 would then navigate it's way onto our "flight deck." We then balance with 1756.
However, this is only one strategy. We have done one other, and have plentiful of more stacking plans. ;)
Why didn't I think of this?

GDC said "Repeated lose of contact". If you loose contact only once, then it's not Repeated.

Good luck a Milwaukee.

Wayne,
Is there any way you can send me a link of that picture of our three robots balancing? No one got a good picture of it from our school, but we'd really like to show it off.

We also need to find a video of us getting up on there. That was so awesome :)
GDC said "Repeated lose of contact". If you loose contact only once, then it's not Repeated.
Call me a hardnose, but I'd have ruled against you. I'd suggest that it is "strategic" loss of contact here -- strategy is to get on top of the bridge, you have to back away and allow the bridge to swing down, and then engage the bridge in order to do that. Sounds "strategic" to me.
At the moment I think you're starring in "A Robot Named Desire", depending upon the kindness of strangers.
I love cool ideas as much as the next guy, but I'd make one suggestion -- get legal. Get legal in the letter of the law. Look at my affiliation, we have some experience in this area. :-) I'm the mentor tasked with knowing the rules letter by letter. Yes, I was around "that year".
At worst case, with the current situation and a hardnose ref, you will take a 9 point foul for a 40 point success. Sounds modestly ok. However, do you have any length to give? Is your flight deck 14" out from the frame perimeter? If not, how about leaving a feeler out on the bridge -- something expendable even, a plastic straw, anything remaining in touch with the bridge as it articulates. The naysayers can go say ni somewhere else at that point. Just a thought!

I think Dan's face really says it all in this picture. Great job! I was waiting to see the success of this strategy!

OK hardnose :) Only the head ref can make this call and they have been told that it is legal so there is no need for them to "get legal"
Sure would be nice to see that in writing, though. All I'm saying. Some independent agreement reached by whatever means falls short of "public knowledge" as appearing in the canon of the game.
It's still a cool idea. Rack and Roll, we built a double lift bot with an aircraft carrier sized flight deck, one of my favorite bots...
Good luck!

Hopefully watchFIRSTnow on youtube will have the elimination rounds up in the next couple days. They have 47 of the qualification rounds currently up. I really want to see a video too. I know that some of our team were taking videos in the stands but we have yet to upload them I think.

Very proud of you guys. These stacking robots seem to be capable of success and i hope your teams and ours continue to be able to show off this unique way of scoring in future competitions. :)
i almost lost my voice cheering so loud after i saw this

Because all head refs share a hive mind, right?

I still can't talk after all of the cheering at Boilermaker.

That guide on top is made of extruded polystyrene and garolite. Almost everyone in the 1732 cheering section almost had a heart attack when it went down, not because we knew that we just lost the match, but because we thought that we had just snapped off the money-maker. Luckily, the tower frame took the fall and the guide is intact and operational.
Also, did anoyne manage to pull off a double-triple balance at Boilermaker? I missed a few of the final matches.

A Robot may only be supported (fully or partially) by another Robot if one of the Robots is in contact with a Bridge.
Violation: Technical Foul for extended, strategic, or repeated loss of contact.
Just for clarification, this was answered in the QnA: (i wished we could link direct...) so this is a copy and paste:
Game - The Game » Robot-Robot Interaction » G30
Q. If a robot uses the ramp to become completely supported by another robot. Will a foul be called if the ramp momentarily disconnects from the robots?
A. There will be no Technical Foul called if the Referee determines that the loss of contact wasn't extended, strategic, or repeated.

In my mind, intentionally losing contact with the ramp for the purpose of gaining points via triple balance certainly qualifies as "strategic." Even if the loss of contact is just momentary. But that's a very vague call, and could decidedly go either way.
If it used frequently, I see no way it couldn't be considered repeated.

We were lining up for the triple balance and 1756 ended up not going up on the bridge straight and got their wheel hooked on the wall. After that 1756 drove in reverse along the wall with the wheels that were touching the ground, making room to put the bridge back down and allowing us to double balance with 1501.

Huh, that's pretty awesome! Nice job on the quick thinking backing off the bridge!

Thanks! Our alliance was able to work really well together and had great communication between coaches/drivers throughout the match. There were multiple times during the elimination rounds that we improvised and changed up our play midgame.

Wow. Great effort by both alliances. Red very nearly managed to make it a double triple until they were thwarted by the bridge dynamics of doom.
I'm impressed by how smoothly the robot stack maneuver appears to have gone.

You guys are awesome, 1501! We are very very proud of you here at Knightstown! Your first regional win was much, much deserved. Love you guys!:D
