I found it very interesting as well. All of the data that I used came from the Galileo predictions document found here.

I then ordered these winning margins in ascending order. My value is simply the negative of the third number in this ordered list.

When you are looking at team X, do you use max/world OPR for opponent Y's OPR, or is Y's OPR also based off what it takes to reach 8-2. This is a very interesting way to think about things, thanks for sharing it.

In all of my calculations, I use the OPR from the above document (I believe this is max event OPR).

I'm not sure if I'm being clear enough. I would be happy to answer any other questions you have about this.

Keep in mind the value of a goalie robot, the matches in where we were matched with two good shooters we (5137) won. There are lots of really good shooters at the finals. Might be a metric you want to calculate I think defense can be as good as offense by ruining cycles of the opposing alliance or at least delaying them significantly while our own alliance scores. We had a zero points in a match because all three robots were defense and two of our other losses was a broken robot in the mix...so that affected our overall stats at the regional but we made an impact and earned the rookie all star. Problem with defense only is we rely on two good offensive robots to provide scoring when that happens good things do. I think with all the offensive firepower at the championships...we will be fine.

Looking forward to St. Louis!

All of these new lists based upon OPR make me .

I have scouted 1885's 20 alliance partners using the schedule currently posted and the video that is available (at least 6 matches per). My mentors & students will scout 1885's 30 opponents over the next 2 days. We start from the team's latest video (including elims) and work backwards in order to see the behaviors we will most likely see at Champs.

Data includes:
HG shots attempted, HG shots made, Inbound attempts, inbound successes, Auto ball attempts, auto ball successes, # of HOT goals, # of truss attempts, # of truss successes, # of trusses to HP or out of bounds, # of times a ball popped out of the robot during gameplay, rough estimate of intake time in seconds (also taking into account driver skills), rough estimate of favorite shooting distance, # of time effective defense was played on other teams, # of times the robot was pushed, # of times the robot was out of offensive position due to playing or receiving defense, # of obvious penalties, # of seconds of lost comms

Trivia: HOT is the 2nd most high goal scoring robot we play with on a per-match basis, but only by < 0.25 goals per match. Can anyone guess who the #1 high goal bot of the 20 is, statistically?

If anyone is willing to trade data on Wednesday, we will have plenty. This data isn't quite free since it took many labor hours to get. Yet if a team can even provide realistic statistics of their own team using the categories above and online video, we'd be more than willing to share all of what we have. The point of the trade is mutual hedging against schedule changes. Unfortunately the schools were out on Spring Break last week, so our ability to get all 100 teams' worth just wasn't there.

Maybe next season I want to develop and test a new metric for FRC scouting: Bumper Quality Rating (BQR).

BQR-5: The platonic ideal of FRC bumpers. Fabric is snug and no wrinkles are visible; no extra material in the corners. Bumpers are installed or removed in one fluid motion. Milled slots or pockets in the plywood backing, sized for minor protrusions from the robot frame perimeter, allow the bumper frame to mate tightly against the robot.
...
BQR-0: Moderate to heavy use of duct tape.

I believe BQR would outperform OPR as a predictor of on-field robot performance.

This. This is awesome.

I think "BQR" would have worked at Chesapeake....I can't tell you
how many robots we saw that had saggy,wrinkled and poorly made
bumpers. We saw a few that had material dragging on the floor that
made me wonder how they ever got thru inspection. I recall one team
there hadn't even made bumpers until they got there.

Post-regional bumpers are the best kind of bumpers.

Well done! I hope all of your legwork pays off (Except in match 31, of course ). Good Luck!

I think Match 31 is too close to call since the margin is small relative to how fast a single cycle can happen. Right now 857 & 2052's stats and play styles are almost identical, so we'll have to figure out who plays what position. Both look like great partners to have. That strategy will likely decide the match flow, and therefore the match. With the right teamwork, we could totally blow that match wide open - or not, if we fail to work together.

Well, here's to hoping we work well together, eh?

Did anyone else get video of Q3? We want to edit together about 50 different perspectives of our human player taking one for the team at the end of autonomous. (He was fine, by the way.) Should make for a fun project on the bus ride home.

If you have raw video files, stop by our pit with an SD card...

At least it wasn't Dean Kamen.

That was the first thing I thought of when it happened.

Huge thanks to 217 Thunder Chickens for custom machining a replacement axle for us! Even knowing that their next match was against us. True gracious professionalism!

Team 2363, Triple Helix, would like to extend our sincere thanks to team 67, HOT, for selecting us to be your fourth alliance partner in the Galileo Division. Also, our thanks to 973, the Greybots, and 2481, the Roboteers for being our alliance partners. It was great fun, and we appreciate the opportunity to have been part of your fantastic alliance. Thank you for seeing the value in our team's abilities!

We would also like to extend a shout-out to our Virginia friends, Sparky 384 for winning the Engineering Inspiration Award, and to 1885, ILITE Robotics for your Innovation in Controls Award. These were well-deserved!
