Best Robot

Chris is me · #1 23-03-2011, 09:48

I'm going to have to say 40. They know how to run a match, and an alliance.

Here's looking at it by OPR (these are just selected teams, I haven't run it for every regional)
1114 @ PIT: 62
111 @ WI: 58
33 @ Kettering: 56
148 @ STX: 56
987 @ SD: 55
217 @ FLR: 54
2056 @ FLR: 52
254 @ SD: 49
40 @ WPI: 40

It's not a perfect measurement (different regionals, different weeks, ignores eliminations), but it gives a nice mathematical ranking and correlates nicely with all the robots mentioned so far in the thread.

Imagine if 111 had a double-tube autonomous...

I assume that roughly 24 hours from now we won't have to imagine what that will look like?

To add to this list 2415 had an opr of 58 at peachtree

I decided to just run it for all regionals. So here are the top 25 OPRs done so far. If a team is there twice, it means they've done two regionals and performed strongly at both (or my script was messed up, which it was. If a team is there twice with the same OPR, it means I double-counted them)

Code:

67	64.1978
1114	62.9768
111	58.752
2054	58.5124
2415	57.7935
234	57.0967
33	56.7075
148	56.5229
1678	55.5372
987	55.1992
217	54.4144
2056	52.7503
217	52.6689
2512	49.8532
254	49.1796
456	48.4294
1023	48.3657
935	47.6648
1676	46.3775
2016	45.5644
1218	45.5229
876	44.9698
573	43.6522

Most of the OPR data is based on one regional per team. Without a full statistical analysis (blocking data, etc.) and more data, the uncertainty in the OPR rankings must be pretty big. My guess +/- 15 points. I agree with a prior post, no one robot is standing out in a big way.

I partially agree with your assessment, but disagree on most of it.

Yes having other data such as blocking data and what not is useful, however its impossible to correlate that into a statistical analysis we can use across every competition.

OPR isn't the end all be all metric of a team's success, but this list has some pretty darn good robots on it so its valid in some sense.

As far as no one robot standing out in a big way, I have to disagree there. Look at 67 and 1114 both well into the 60s. The 3rd highest is 111 at 58 and then theres a steady decline from there. These 2 teams to me seem to be standing out in some degree above the rest. However, taking a team with say a 58 OPR and dropping them in the same competition as 67 or 1114 may result in either team's number fluctuating based on the equalized playing field.

Just my .02

Actually 67 has the highest with 64.1978. The Week 3 results will be out tonight at http://frctop25.com/ accompanied by the live broadcast revel at 10:30pm. 1114 has the top spot in both polls from W2.

Speaking of the FRC Top 25...

It's actually a more direct way to get the response, or submit your opinion. There are two polls, one expert and one not.

Can someone clarify what the OPR is???

Thanks

roystur44 · #12 24-03-2011, 14:47

Don't forget about Team 971. Due to budget constraints we don't get to play till week 5. All I can say is we have been watching, practicing, learning from all the mistakes, and making improvements in all areas we can think of. The robot is the best robot we have built so far. She's fast and smooth and has a few tricks up her sleeve

We play at SVR next week. Take a peak.

OPR is Offensive Power Ranking

It the result of a moderately complex calculation. Essentially, your OPR is how many points your robot is expected to contribute to your alliance. So those top robots are expected to contribute about 60 points to an alliance's score. A more average robot this year is in the 5-10 point range. A negative score indicates your robot/team tends to take penalties or get in the way.

If you search for the oldest big thread that mentions it, it'll have the mathematical definition. If you find the "easy to use OPR" thread, that includes my program which can calculate it.

Well, not too sure about the best robot because we dont want to jinx anyone!

Happy regionals!
