FIRST 2012

Alternate title: I’ve almost been doing this longer than the students have been alive.

It’s January which means another FIRST Robotics season is upon us. This means six weeks of having nearly every thought consumed by robots and ten hours a week at the high school. This year, I’m finally not a student myself so I’ve got far more time to devote (and am actually available to answer questions).

First off, this year’s game. It’s basically a modified version of basketball. A three minute animation explaining it can be found here.

Again this year, we’re working with Thomas Jefferson, a magnet school for science and technology. The students are very smart, very driven, and basically just need our help to keep them from building something far too complicated and to re-explain how PID controllers work.

So far, they’ve got a priliminary design complete and have welded most of the chassis. Pretty good progress, seeing as we’re now about halfway through the six week build season.

And, now, photo overload.

Done: Item 68 – Have robotics team make it to the regional finals.

Well, I didn’t think this would be accomplished. No, that’s wrong, I thought it would be but far after the 1001 days were over. I actually thought about changing it to something else because the team’s success is not under my control. Then couldn’t figure out what to change it to: get two new sponsors, start some sort of spirit team, get three more girls involved. Out of laziness I kept it as written.

Thursday, Friday, and yesterday the LA Regional was held up at the LA Sports Arena. I didn’t attend Thursday’s practice rounds due to my Power Plant class but apparently we had lots of problems. We were seven pounds overweight (goodbye outriggers to keep us from falling over, 2 wheels, and little bits of aluminum) and had a major coding error that made our pneumatics cease to work after autonomous hybrid mode. But we finally passed inspection and made it to every single practice round – plus several more when FIRST was struggling to find working robots to fill out the rounds. Friday we won six out of seven qualifying rounds. I’ll spare all of the details about the one loss that should’ve been a win – it involves 1/4 of a second of lost radio communication and FIRST being idiots. Ended the day ranked 4th. Yesterday we lost (I think) both of our last qualifying rounds but finished as the 11th place seed. Despite our high seed, I was still surprised when we were chosen to join the 4th place alliance. Of course, five or so teams declined to join the alliance before us – the plight of a rookie team with a not-great robot that gets ranked well – but we were excited nonetheless. We ended up losing in the quarterfinals; the lack of strong alliance mates plus our falling over 30 seconds into the second match did us in.

But look at it this way: our previous best seed was 25th. Last year was the first time we even made it to all of the practice rounds. I have a feeling we’re going to have a much easier time recruiting students to join the team next year. We’re even talking about building two identical robots next season.

My best shot of us in action isn’t real great. Seating isn’t exactly ideal for getting action shots unless you’re on the crew (and then you don’t care).

The balls are randomly ordered on the overpass so you never know if you’re ball will be in front of you when you start.

Alliance pairings always take forever. Tito, our rep, is just to the left of the overpass.

Choosing Alliances

I had fun making fun of several of the guys for playing chess in the pit between rounds.

It’s DONE!

I can stop saying “Once FIRST is over..” or “After FIRST..” because the robot is DONE. Okay, not totally complete and working 100% properly but it’s at least in the crate and sitting in a warehouse somewhere in Downtown LA. We won’t see it again until the regional Easter weekend (great timing, huh?). I’m sure we’ll have a couple meetings to get all of the tools together and iron out logistics prior to then but at least I get a break from robot-building. I’ve now got back my Monday, Wednesday, and Thursday evenings as well as my Saturdays. Don’t get me wrong, I really love being a mentor and participating in FIRST in general but it’s nice to have my life back.

Oh, here’s a quick pic of the finished ‘bot, taken by Kathy, one of the teachers from the high school. If you click on it, you’ll see the Flickr page which shows the time the ‘bot was declared finished: 5:38 am (okay, that’s Eastern – it was 2:38 am here).

FIRST 07

I created this mosaic awhile ago and totally meant to post it but, well, that didn’t happen. So here it is now, my favorite photos from last year’s robotics season.

And it Begins

This morning was the announcement of the 2008 FIRST Robotics game. Think race with giant balls that can be pushed in front of you as you go in laps.

Fun with a Big Ball - 1

That’s a nylon ball with a 40″ diameter, in case you’re curious.
