Team 578 - Blue Lightning, had a great time at the Canadian regional.

Thanks to all the Canadian teams for your warm hospitality (we needed it, under the masonite floor was an intact hockey rink - ICE included! :c)

We had one totally awesome match. We were doing our best to block the ramp at the bottom, to keep both robots from the other team on our side

and we got smacked so hard the shaft on our front wheel snapped - and the skyway wheel fell off our Bot!

The driver almost hit the kill switch, but he saw me on the side line jumping up and down, waving towards the ramp, screaming, " GO! GO! GO! GO! GO!"

it took a good 15 seconds, but our 4-wheel-drive-minus-one robot dragged itself up the ramp, leaving the 4th behind on the carpet.

I dont remember what happened after that - it was the coolest thing Ive ever seen.

FIRST is awesome!

And what kind of person says robotics competitions aren't exhilerating. :)

The matches where things go wrong but still end up the right way are the best ones of them all :)

Awesome. As much as people like to complain about the contact element of the games, contact is what puts rear ends in the seats. It's fun to watch, and it gives you an opportunity to fix your robot.

We had a match last year, in our division finals at nationals, when our goal grabber was ripped off the robot in a battle with 469 and was hanging by a thread (it might have been a pneumatic tube). Our drivers and those of 25 still managed to pull out an amazing victory with some great driving and more than a little luck.

we won a match with one of our chains laying under the mesh. Truth, though, I wasn't as thrilled as you. the sprocket was off because we didn't locktite the set screw. we had some good ones, tho, like one match, where the real monster of the day, a team who had been knocking all the boxes down in auton, zipping under the bar with ease, team 547, match 62 from stl.

Anyway, we had gotten together with our partner and agreed that our auton would put us at the bottom of the ramp, waiting for the bins to fall so we could try to persuade 547 that they would look better on OUR side as soon as human control began. Anyway, the programming paused at the bottom, but then a well meaning bug in the program made it continue in a straight line. We hit the boxes just as 547 did. Our robot had more power (same four motors, geared to half the speed) and the boxes shook alittle, but didn't fall one way or the other. It was just us on one side, 547 on the other, and the immobile boxes in the middle. Unfortunatly, our wheels were on the mesh, and they had gotten there slightly before us and had the sticky top to sit on. Our wheels spun, and they won the match. Still, a moment I will never forget. Our pod, 877. I don't know If I am right, but i believe 877 weighed in in seventh ranked. We faced them again in match 110, last of the quals, and defaced them and our pit partner 73-3. So much for strategy, but I was hoping a landslide victory would encourage them to select us as alliance mates. Well, really I was just into the heat of the thing and couldn't see their side very well and thought they were winning, but it was worth a hope. Too bad, no joy here.

I think play of the day at the Cdn had to be one by my team in the semifinals(i think it was the semis... that or the quarters) Big Mo, one of our alliance partners had been flipped on the ramp.. it didn't look like they were makin it up.. which got us all worried cause we needed koh to win the round.. well our driver went and rammed into Big Mo a lil... and somehow in an amazing feat, flipped em back over!! It was the coolest ever! We managed to get both bots on top after that if I remember right.. hehe it was so cool!!

That reminds me, if anyone happens to have vid of that, if they could toss that my way, I'd love a copy! Thanks!!

At the spbli regional I saw this happen at the practice round:
Robot A runs into wall flips itself over.
Robot B runs over Robot A's arm and gets stuck.
Robot B helps Robot A flip back over.
Robot A and Robot B are now intertwined.

We had a similar experience at UCF with the wheel falling off... if you could watch match #101 at UCF on www.soap108.com, im not the best at links, and dont know the exact address of all the movies.... but our DRIVE wheel fell off (2 WS up front) and there were two robots on the ramp. w/ about one sec left we got up the ramp and had enough power to knock the other one off giving us a 5 point victory, or some ridiculously low number like that. It was crazy style up there. I think our driver was about to hurt me b/c i kept yelling at him to get up the ramp not knowing that he couldnt really steer the bot too well....

We sheared off an arm one match. We were just driving along when we hit the lexan and the anouncer says "And 696 has just sheared off an arm!" You could just imaging the expression on my face (I was driving). I didn't even see it happen or see where the arm went.

That match was awesome. The fact that you guys and 25 ended up on the same alliance means that some people didn't do thier scouting. No one should have let that happen.

Good job in that match guys. I have the vids but it'll be a bit before I put them up; note that I was also yelling at you guys while pushing and jumping up and down so the camera work is off by quite a bit at times.

Good job 783 and 314; we picked you and you did what we needed.

Awesome! when you do just give me a shout.. my contacts should be somehow attatched to my name.. thanks a ton, I'm thinking of trying to work it into a tech project.. somehow... I'll find a way (maybe hide it in a transition..)

I couldn't believe what happened to your wheel (I was in the driver booth beside you guys). We still won that match also I believe.

Frank,

That was a neat match. If you remember, once driver mode started, a lot of the bins came your way. This was due to a feature we have that we only needed when we were up against you and the bins. Our arm assembly actually pushes out and then upward about 4-1/2" by pnuematic cylinders. This allowed us to flip them over the top of your robot.

Thanks for the kind words! St. Louis was fun.

We had something similar happen......
In one of our matches a chain fell and I had to drive my robot with only one wheel of the 2-Wheel drive close enough to knock down a stack and i was lucky that I had the arm swing out and hit the stack after i got within a couple feet of it. We would have lost the match if i wouldnt have gotten there.

Wow...that's awesome...I wish I could have been there to see it:)

I know that feeling-

It was our first match at Philly- we had homecourt advantage and all, and we really wanted to do well..

anyway, we hit the stack first, went over, and then somehow flipped over. This never happened at Chesapeake so we were all bummed.. Our arm driver decided we had nothing to lose, and tried to flip us over.. Amazingly, the chippy pulled through, and we came back to life.

We ended up winning this match with 213 QP's

I saw at one regional the robot freak out, spin around for about a minute on the top of the ramp then start to smoke as though it was about to blow up. Our team happened to have treads and when we hit other teams at high speeds, we ran right over them and left tread tracks all over their robot. One team we faced in Sacramento came to Silicon Valley and it still had the same scuff marks.

In the practice rounds, our robot was so tippy that when our autonomous took us straight into the wall, we tipped. When we went straight over the ramp and hit boxes, we topped. Of course, we rebuilt our robot and finished 10th without a single tip in qualifying matches.

What did your team do to fix it. Add stabilizers or just cut the height in half?

since people have mentioned all the damage, I felt like commenting. Some people dislike this game because it is too intense. The way I look at it, it forces the teams to create a robot that can not only do a task and do it well, but also stand up to the abuse of use. This, I believe, has a really good real world application to it. It forces teams to consider the entire design process, and not just finish when the robot is built. I feel that this game, more than others, brings forth the true meaning and practices of engineering.

This is also why I had such an awesome time at the regional. I can't wait until Houston.

I have a very strong feeling this was us at Sacramento :o ... We are not going to be drilling near those speed controllers again!

In order to fix our robot, we removed all our devices and were left with a speed, manoeuverable, strong, extrusion box on wheels. We eneded up at 87 lbs so we added 10lbs of steel tube to the bottom of our bot to lower the CoG even more.

at the Canadian regional there were 8 seeding round matches per team - that means you spend:

16 minutes on the playfield in action and

36 hours in the pits (if you stay as late as possible)

all the magic on our team happened in the pits. After the buckeye regional we discovered (by watching the videos) that our flying squirrel was only takeing out two columns of boxes, and it was folding way back.

So we came up with a hindged version on paper, brought all the raw materials with us, and made it 5.5 feet wide in the pits on thursday.

we also moved our battery from standing up vertical on top of the frame, to lying horizontal below the frame. That took two days to implement - we didnt get it attached till saturday morning (after a collision had knocked a hole large enough in our plexiglass panel to run the battery wire through :c)

we also had to repair damaged transmissions between matches 5 or 6 times. We are going to open a transmission repair shop "your tranny fixed in 30 minutes or less, or your next ones FREE!"

Team members who sit in the stands all day miss out on the real action - and the pits REALLY come alive after 6PM on thursday night :c)

When our grabber arms broke at Suffolk last year and they were flying around. I think the limit switch wiring was the only thing that held them on. We dragged them up the ramp, lucky they didn't turn us off for protruding through it. As I remember we mad it up on the ramp fine put down our suction cups and got the points. :cool:
