Re: Archimedes 2013!!!
 

OPR predictions are generally 81% correct within an event. With the number of improvements teams make between the regional and championship, I think it will sway close matches significantly.

Also, if 3314 seeds first, prepare yourselves for some scorched earth.

Re: Archimedes 2013!!!
 

I'd expect scorching from any team (barring maybe 868 and 126) that seeds first and doesn't have a >3 disc auton.

Re: Archimedes 2013!!!
 

Inb4 11 and 3314 actually DO go 8-0

Re: Archimedes 2013!!!
 

I highly doubt either of us will go 8-0. I see 33 and 469 having the best chance at 1st seed.

Re: Archimedes 2013!!!
 

Scorching would make this division VERY interesting.

Re: Archimedes 2013!!!
 

Unfortunately, I think performance this year depends greatly on match schedule (more so than years past).

3314 is a great shooter. The won the Bridgewater district as the #1 seed, but then they were on the outside of elims at MARC for who knows what reason. I can't explain that, except for poor luck of the draw at MARC.

Drawing from MARC, alliances that succeeded in elims did not focus on defense whatsoever. The only dedicated defenders were to block full court shooters, and it was extremely effective. I think an FCS that can't get under the pyramid even making elims is far fetched. It's too easy to stop.

If I had a 3 disc autonomous mode, I wouldn't trade it to stop the opposing alliance from getting an extra two discs on the center line. Perhaps after you shoot, but certainly not before.

Re: Archimedes 2013!!!
 

A journalism student traveled with our team to the 10,000 Lakes regional. Here is the video she made.

Re: Archimedes 2013!!!
 

Not to take anything away from them(they did almost win two events), but 3314 also had a fairly easy schedule at Bridgewater, IIRC.

Re: Archimedes 2013!!!
 

...

Re: Archimedes 2013!!!
 

Using OPR from each team's best district event, OPR predictions were 82.4% accurate for MSC.

I think it will probably be right around 80% for CMP as well.

Re: Archimedes 2013!!!
 

As pointed out earlier that's within an event, using all match data to recalculate and fit what would've happened if OPR was 100% accurate.

Also, I would like to point out that OPR predictions using Friday's match data to predict Saturday performance at Crossroads was 16 for 24 (or 25 if you count ties being wrong), and Crossroads had a significantly higher average OPR than most other regional competitions, similar to what Archimedes is predicted to have.

Re: Archimedes 2013!!!
 

That may be, but I think it speaks volumes about the style of game this year. With 100 teams and 8 matches it's going to be a dog fight to get in the top8, and EVERY autonomous shot matters. The 6-7 fantastic robots you see in this division may not have their fate in their own hands; that's up to the match schedule gods.

Re: Archimedes 2013!!!
 

Im hoping there wrong too.. and I would say around 75%

Re: Archimedes 2013!!!
 

This division just got WAY less predictable. I think if a non-favorite team seeds first (i.e. 3314 or 11 like the spreadsheet says) the field becomes wide open for some very interesting alliance selections. I expect multiple declines and potentially some powerful low seed alliances.

Re: Archimedes 2013!!!
 

Is there a particular reason you used OPR and not CCWM?

Re: Archimedes 2013!!!
 

With the preliminary schedule and the results that came with that I think every division is gonna have a fun, exciting, and down to the wire finals. I wish everyone good luck and safe travels on there way to St. Louis

Re: Archimedes 2013!!!
 

I wanted match scores that could be used to calculate reasonable rankings. Since CCWM is related to winning margin and not match scores, it wouldn't have been as useful. I've seen lots of people look at the accuracy of OPR predictions, but haven't for CCWM predictions. If someone has data that shows that CCWM predictions are more accurate, I might consider doing it for next year.

A slightly better way to get match scores would have been to add the alliance's OPRs and subtract their opponents DPRs, but that's a lot more work.

Re: Archimedes 2013!!!
 

3173 will be keeping an eye on you guys at our end of season party this week!! Good luck to our captains from Boston, we hope that you guys have better luck at this competition!

Also, we felt bad that you did not have enough buttons to give you guys at the end of Boston, if you can tell us a way to send them to you we could mail them or something before CMP. And our head programmer picked you guys in our Fantasy FIRST draft last night ;)

Re: Archimedes 2013!!!
 

Here is a link to 973's collection of pictures; We are still looking for a few more.

Re: Archimedes 2013!!!
 

Thanks a bunch for this.

Is there any way to put it in numerical order :o its a bit hard to use currently :(

Re: Archimedes 2013!!!
 

We've had some fun with that as well.. unfortunately the pictures have to be saved with the team number as the file name for our system. They are ordered by google drive numerically but strangely not sequentially. So as you look for teams they will be grouped together by numbers from left to right. Hope that helps

Re: Archimedes 2013!!!
 

3478's picture is of their last year's robot.
And you can just Ctrl+F to find the team you want to find.

EDIT: There's also no picture of 3314

Re: Archimedes 2013!!!
 

Attached is a little better photo of 1519's robot as of the North Carolina Regional.

However, our robot, "Discobolus Rex," will hopefully look fairly different by Thursday at CMP. Using 27.0 pounds of our 30.0 pound fabricated parts allowance, we have a lot planned for Wednesday night in order to hopefully increase our OPR from the 64.1 we achieved at NCR to even more at CMP...

By an hour after the pits open on Wednesday night, we hope to have reduced the robot we pull out of the bag to nothing but a drive base! Then, we plan to mount a whole new upper frame with a revised more-accurate shooter. We'll then disassemble the old 30-point climber (we never actually managed to get above the 10-point level in a competition match, although we had it mostly working with essential human assistance on the practice field) and re-assemble it in a different configuration and a new movable carriage to re-make it into a 10-point quick-hanger. We'll also move the battery from the front of the robot to the back and accordingly move the main breaker.

We'll try to remember to get photos at opportune times -- looks like it will be a busy night!

Re: Archimedes 2013!!!
 

If you change the filenames of short-numbered teams to use leading zeros so that all numbers have four digits, you may able to fix that. (e.g. 0011.jpg or 0126.jpg)

Re: Archimedes 2013!!!
 

Thanks for the responses. We are still looking for 13 pictures:
321
433
1448
1660
1756
2081
2408
2457
3008
3314
3478
4067
4553
If anyone finds any other teams with outdated/incorrect pictures, please let us know and we will try to get it updated. If there are better pictures out there send us a link and we'll get them in.

Re: Archimedes 2013!!!
 

Re: Archimedes 2013!!!
 

Not gonna lie, I'm pretty excited for Match 19... :D so many good teams around, it's a great experience for our North Idaho team

Re: Archimedes 2013!!!
 

The leading zero problem doesn't affect our scouting system at all. We pull pics by function of team #, and the team's are numbered in our system w/o leading zeroes obviously. If we changed to leading zero, we'd have to also change this logic.

So, sorry guys; No renumbering in our gdoc folder, but feel free to take the pics and do whatever you want with them.

Re: Archimedes 2013!!!
 

I have attached a better picture of 836 to this post.

Note that we are using some of our 30lb allowance to rework the shooter to prevent the jamming issue that plagued us for so long.

Can't wait to see all the robots.

Re: Archimedes 2013!!!
 

Seeing http://www.chiefdelphi.com/forums/sh...&postcount=136 made me curious who had the "easy" or "hard" schedules in Archimedes. Using the same analysis method, with one minor change*, I generated the following list:

*Instead of ranking teams by OPR 1-99, I ranked them by OPR if the team itself was removed from the division 1-98. I think this prevents the average result of a large number of samples from breaking down into a strictly OPR based list.

In no way do I think this is a very good way of ranking match difficulties, but it was rather easy to do.

Re: Archimedes 2013!!!
 

Well I'm glad we have the, uh, honor of having the 11th most difficult schedule in the division. Let's hope the scouts are watching closely!

Re: Archimedes 2013!!!
 

So the lower the number, the tougher the division schedule becomes? I am kind of confused to what you actually did.

Re: Archimedes 2013!!!
 

If I understand the original model,

Re: Archimedes 2013!!!
 

So the lower the number means that team has a higher SOS?

Re: Archimedes 2013!!!
 

Yes.

Re: Archimedes 2013!!!
 

Yes, this is correct. However it's still important to realize that this approach has numerous shortcomings.

As an extreme, place the #1, 2, and 3 teams against #97, 98, 99.
The #1, 2, 3 teams would each get a huge boost to their result, making it seem like an easier schedule, whereas #97, 98, and 99 seem to have very hard schedules. But this is only for 1 match, and this 1 match will have a disproportional impact on the final ranking (it might account for well over half the "points", while it only accounts for 1/12 of the final seeding).

Re: Archimedes 2013!!!
 

Did you remove surrogate matches from your calculations?
If not I think you need to remove the third match of 433, 930, 987, & 3044

Re: Archimedes 2013!!!
 

I forgot about those. Corrected results are below, after removing those 4 surrogate matches. As before, lower number in "difficulty" column = harder schedule.

Re: Archimedes 2013!!!
 

Looks like all the other fields have the match schedule and results up, but not Archi. What's up with that?

Re: Archimedes 2013!!!
 

Looks fine to me...

Re: Archimedes 2013!!!
 

Dang cache!

I had to do a shift-reload to get it.

Re: Archimedes 2013!!!
 

Spyder has everything updating too.

Re: Archimedes 2013!!!
 

rest assured, we did not go undefeated so we will not have the opportunity to be turned down by many teams. and while destroying the ability for the best of the best to be together may be some people's style, as a second pick worthy robot, we understand our limitations and do pure best to help our alliance win every match. we are certainly not going on the fieldand doing nothing. and as many of the MAR teams that I respect know, we would rather play against three good robots in the finale than screw alliance selection. we want to see Archimedes to win Einstein, maybe with a MAR bot in the alliance.
On a side note, thank you to 2016, the Mighty Monkey Wrenches for saving us when we had the perfect storm of disasters happen on the way to st Louis which had us finally arriving at the dome around noon on Thursday instead of Wednesday by seven. School bus accident. cancelled them delayed flight, missed connection, forced to spend the night in Charlotte rather than st Louis, and delayed a.m. flight. my team is thankful we are even herer to compete this weekend. thank you 2016 for putting up our Egyptian pit. fixing our bent axles. and being an amazing team. they might be ranked low, but I hope you have them on your radar. maybe someone will have enough confidence in 3314 to choose us for our reliable autonomous, three cycles, ten point hang, and our 80 prior matches of experience this season. Good luck to everyone on Archimedes.

Re: Archimedes 2013!!!
 

Match 120

1075-987-2415 Red
33-1610-2543 Blue

211-85, Red

2415 cements #1 position.

Re: Archimedes 2013!!!
 

congrats wiredcats. well deserved!

Re: Archimedes 2013!!!
 

Congrats to all the teams in Archimedes!!! It was an amazing weekend to be on the field, and to be able to watch such high caliber teams was truly an awe inspiring event for me personally. I was privileged to have been able to be a part of your referee crew on Archi!!! That being sad, I am hoping the FIRST community here on Chief Delphi can assist me in looking for my WALL-E figure. He went missing from the Archimedes field on Saturday and I am trying to find him. My sister bought him for me a few years ago, and they no longer produce/sell them. I have taken him to numerous events over the past few years, and have a whole facebook album devoted to him and these pictures. I am saddened that I will not be able to continue this album, and many of my friends were upset about this as well. It has brought a lot of joy to many people both in and out of FIRST to see the picture updates. Attached is the last picture I have of him from the Archimedes field. If you could please ask your teammates to see if anyone may have accidentally taken him I would appreciate it!!!

Re: Archimedes 2013!!!
 

First off, I had a great time at the Championships as did our entire team. The Archimedes Division did not disappoint this year. I always enjoy meeting and working with new teams each year, such as 33, 469, 291, 1714, 694, 868, 2590, 948 and seeing old friends like 51, 71, 254, 365, 525, 973, 1902, and 3245. I wish the Championships were a few days longer so we could get to know more, but I guess that will have to wait until next year now.

I want to thank our Alliance Captain, Team 2415, for choosing us to be a part of the #1 seed. Going undefeated at the Championships is never easy and you guys earned the #1 seed with your solid robot and game play. We have still never gone undefeated during qualifications at the Championships after coming so close with one loss in 2006, 2008, 2012, and now 2013. (This year's loss is going to sting for a while.)

I also want to thank our other great Alliance Partner, Team 2959. You guys were such a great scoring machine (worthy of a 1st pick) that I was shocked that our Alliance was able to steal you at the end. A great undervalued Michigan team that was a pleasure to work with this year.

Congratulations to Teams 33, 469, and 1519 for winning the Archimedes Division. The finals matches were incredible and all six teams left everything out on the table. I wouldn't want to win or lose any other way. We were pulling for you all the way through Einstein.

Congrats to the Archimedes Teams for their Championship Awards:

254 Industrial Design Award
1902 Imagery Award
33 Quality Award
3478 Engineering Inspiration
2614 Entrepreneurship Award

And again, we were sorry to Team Crush for the hit in Match 2. I don't think we could recreate that if we tried, but at least it is a video clip that we'll both be remembered by for a while. As Greg mentioned in another post, they were next to us in the pit and were gracious enough to give us use some of the glue/solvent, with which they repaired their robot after Match 2, later in the day after we cracked a part of our intake chute. Great team from our neck of the woods (or desert).

Good luck to all of the teams in the offseason. See you at IRI or next year!!

Now back to work....

Re: Archimedes 2013!!!
 

This message is simply to thank the many teams on the Archimedes field that made the 2013 Championships an unforgettable day for everybody on 1519. This will probably be a "tl;dr" for many of you, but we'd like to thank you anyway!

During the first three days of the event, there were countless teams that helped us in various ways. We thank all of the teams that tolerated our rudeness on Wednesday night when we shooed you away so that we could completely rebuild the top half of our robot with a different climber and improved shooter. (This might be the best thing about the Wednesday night pit time - uninterrupted time to work on the robot!) On Friday, we could not have repaired our shooter without the encoder MARS 2614 generously gave us, and the Red Devils 1334 repeatedly helped us out with things like thread taps, talcum powder, and encouragement. Other teams made space for us on the informal practice field to test full court shooting, and yet others provided stories of what tricks or techniques worked for them when making the long shots. Please know that you were each some of the many teams in FIRST that helped us this season and you deserve a portion of the credit for any recognition we received. Thanks!

During the qualification matches, our partners were generally fantastic in the strategy sessions, demonstrating the gracious professionalism of FIRST by being willing to set aside their own interests in showcasing their robot or simply doing what they wanted to do, but rather collectively working with us to come up with an alliance strategy that was in the best interest of winning of the match, even if it meant we or they would be playing lowly defense instead of high-profile shooting. Sometimes key, timely, penalty-free defense is the key to winning a match!

For 1519, though, this posting couldn't be complete without a big THANKS to our alliance partners, The Killer Bees (33) and Las Guerrillas (469)! We're especially thankful to the scouting and strategy folks on 33 who saw the potential in our robot and team to bring some significant capabilities and unique diversity to complete the 33/469/1519 alliance, despite our rather mediocre 50th place ranking in Archimedes and our 4-4 record. We made some significant improvements on Friday evening / Saturday morning which were demonstrated in our only Saturday morning qualification match. Before 33 picked us, we were concerned that we may be packing up our pit in a few minutes. Instead, our robotics team had the most incredible ride of our 9 years to date! However, we wouldn't have experienced any of it without 33 and 469 leading our alliance. We're thankful to have had the opportunity to play in the big show, with all of the FRC world watching.

The whole concluding day of the 2013 FRC Championships is a day I'll surely never forget. Thanks to 33 and 469 for inviting us to share the magic with them. We'd love to be allied with either of your teams again some day; I can only hope that your teams both feel the same. Thank you!

We'd also like to extend our congratulations to Team 3467, Windham Windup, of New Hampshire for winning the only judged award for veteran teams on the Archimedes division. Your robot transformation at the Pine Tree Regional was part of the inspiration that we could do a complete upper robot rebuild at the Championship event. It was definitely worth it!

There are a few other non-Archimedes teams that deserve our thanks, too: Without Team 435, The Robodogs, picking us at NCR, we might not have been in St. Louis at all! Back home in New Hampshire, we would have had little chance to develop the FCS in the first place without the practice field space of 1512, the Metal Vidsters, of St. Paul's School.

Thank you all!

Re: Archimedes 2013!!!
 

Sorry to bring this back up, but does anyone have video of 254's quarterfinal matches? All I found video of was 1519's matches.

Re: Archimedes 2013!!!
 

http://www.youtube.com/user/RobotBillMD?feature=watch has all of archimedes I think (although from a weird angle)
