Karthik & 1114: Effective FIRST Strategies 2012

I can only guess it has something to do with the highly "inseparable" nature of the bridge, as well as the Coopertition Bridge. I think a Hybrid-only OPR and a Teleop ball scoring OPR would probably be more useful than general OPR this year - an option not present in the past but now available via Twitter.

The hybrid and teleop-only stuff is available simply because it's in the team standings page. As long as FIRST breaks out individual stats in the standings page, you can do the same regression math and get bridge/hybrid/teleop ratings.

My own thoughts on why it's not as effective this year as past:
-The 1 CP = 5 points hack isn't perfect
-Many top-end teams (including 1114) sacrifice a ton of potential offensive points by sitting on the CP bridge at the end of a qual match waiting for a cooperating robot. This means their OPR will underestimate their 'true' offensive value
-Teams like 1114 that hop on the co-op bridge early and get rejected (or fail to balance) will have sacrificed lots of offensive scoring and gained nothing for it. Result: elite team with a depressed OPR.
-Seeding high in this game depends on CPs (depends on bridge ability and luck) and match wins (depends on offensive power, bridge ability, and luck). A 1-dimensional measure of a team isn't going to predict a high seed.
-Success in eliminations depends on offensive power, robot shape, centres of gravity, and bridge ability. Again, it won't be captured in a 1-dimensional measure like OPR
-Fouls will elevate a team's opponents' OPR rather than depressing their OPR like penalties used to. Result: a team that causes lots of fouls (and thus contributes lots to their opponents' OPRs) won't get detected
-For bridge power, a team that spends 2 minutes to balance will be rated about the same as a team that spends 10 seconds to balance, assuming they balance about the same # of times

All that said, the correlations between OPR and qualification match win rate are pretty good this year. In 2007 and 2009 it was useless because of the exponential scoring and human scoring respectively. However, it's usefulness as a predictor of who would be best for a team to draft for elims is much reduced. Elimination success this year depends on less-measurable qualities like robot shape and CG and how well the robots work together.

Minor quibble: Chris said Teleop ball scoring OPR. This is available only from the Twitter data, because the Team Standings data folds Foul Points in the TeleOp sum, and doesn't provide a column for Foul Points to let you subtract it out.

Where do we get our passes to attend this event? I have bought mine, I just don't know where to pick up the pass.

Karthik - I would really love to attend this in person. Unfortunately, as an inspector I suspect I'll be just a tiny bit busy Wednesday night. I'll look forward to the update on SimPhone though.

From the registration webpage:

Passes may be picked up in the America's Center starting at 03:00PM CST on Wednesday, April 25, 2012 at the Robotics Conference registration table located outside of room 264.

Thanks to everyone who came out and attended this presentation. I was really energized by the standing room only audience that was present, and I'm confident in saying it was the best session I've ever delivered. Our team did tape the entire session and we hope to have it hosted online shortly. Links will be posted in this thread as well as on the various 1114 social media accounts. We'll also be adding this presentation to the SimPhone App.

Special thanks to Colleen Shaver and Nick Skripsky for all their hard work in making the FIRST Robotics Conferences possible.

I hope it'll be up soon. I really really wanted to attend, but my team desperately needed to pass inspection Wednesday night, and there's where being a valuable Pit team member has it's downfalls. Thank you Karthik for all you do for FIRST, Simbotics, and changing the world.

As someone who attended your presentation I must say that it was simply outstanding. I found it thoroughly interesting and informative. I am planning on showing this to all new members of our team next year and possibly the teams we may end up mentoring.

I'm so happy this was recorded! Like many others this presentation has been at the top of my list since I was a freshman, and have never been able to attend. 1114 is an amazing team, and I hope to be able to show my team this presentation and hope that they can benefit from it.

Karthik, will this seminar be available soon... we're chomping-at-the-bit to learn from Simbotics! ;-) THANKS!

Hey Michael, our media team is working away on getting the video edited and integrating the slides into the product. It should be online in the next few weeks.

I hate to come across as nagging, but how's the video coming along? Or, if it's up, could someone direct a somewhat lost mustang to said video then?

Still being worked on, but should be online soon. It will be publicized via the 1114 Twitter and Facebook accounts as soon as it's available.

Thanks Karthik. I can hear my parents now..."Cal, get off Facebook and do your summer assignments now!" "But mom, I am doing my Robotics summer homework; I'm studying 1114 so I can be a more effective Team Captain!"

C'mon, hurry up 1114!
