OPR FIRST 2014

Unrated

NOTICE: Version 2.1 currently has some bugs and I am working on fixing them within the next week. Please bear with me as I try to get it ready for the upcoming 2014 season.

This application is designed for students, mentors and spectators of FIRST Robotics Teams. The app contains functionality to sort teams at any regional by OPR, Average Score, Max and Min score, and Regional rank. Using these categories, the app has the capability to predict any match after match 30 in a regional. The live updating capability allows for live calculations of OPR which can be recalculated before each match to give users a preview of what is to come up in upcoming matches. In addition, team listings, award categories, and match schedules are easily available to view and search.

Available Functions in current Update
Team Searching with information regarding location, nickname, sponsors, etc. of each team
Information for each regional regarding team listings, Match Results, Sort-able Stats, Match Predicting(by OPR and Awards

What is OPR?
OPR – Offensive Power Ranking. The term was coined a few years ago by Karthik of FRC Team 1114, Simbotics. OPR is considered the average contribution of a team to a match. The higher the point value, the more that team can contribute. Teams can have a negative OPR, as they can cause penalties or inhibit higher scoring teams from scoring. NOTICE: OPR may/may not be an accurate description/predictive quality of a team. Please use the data at your own risk and consider how it is calculated. OPR is calculated by taking into account every match score from every match and put into a matrix. Using linear algebra, this is then converted using Cholesky Decomposition into the OPR values. Other factors may influence OPR in a match and for more information, Simbotics strategy session at the world championship in 2012 gave an excellent description of why OPR wasn’t as relevant in the 2012 season.
The Match Prediction tab in this application utilizes OPR to attempt to predict the outcome of a match

Where I get my data:
Special thanks to www.thebluealliance.com for producing their APIs in which I use. Also, I obtain data from FRC-Spy located on chiefdelphi.com, and from usfirst.org.

Newer releases may contain:
Picture matching ability to match robot pics with teams, previous year data, and ability to save teams as favorites and track teams. Also, I eventually would like to add Fantasy FIRST functionality which information can be found on chiefdelphi.com.

Nah Our team played all day today and nothing showed up on this app. Sorry guys but I'm sticking with Spyder

After fix it will be great The application doesn't leave the opening screen. Search does not function. Last year it was great. Samsung g3

It Works! The addition of a way to view the elimination schedule/bracket/results (and run predictions from there) along with a updated theme would make this app perfect! Maybe even automatically predict the entire elimination bracket just for fun? The most recent update fixed the crashes I was experiencing and having the predictions at my fingertips will surely be handy come next week! Predictions I tried for already completed matches were surprisingly accurate.

One of the best FRC apps for Android Great for some quick live analysis of robots in the middle of a competition when you can't get to your scouts. Also works when FRC Spyder is down which is quite nice. One star off for the ugly interface, would be nice to have it look holo but it's perfectly functional. Won the Buckeye Regional using this app!

Love it Works great for team 27

Very unattractive, a bug, but solid stats Thne stats seem to be solid - for the events I can load (the bug). On a N4 running 4.2, there's no menu button allowing me to access options. I recommend checking out ActionBarSherlock and the Android Design Guidelines too, for some sort of Holo theme, not Froyo.

Could you give me more information on why it did not work? What regional were you playing in, did you have an internet connection to update, and were you able to update?

This is a UI fix that I need to implement. The words that say "search by team or regional" are actually a textbox and if you click on it, you can type stuff to search for. Hope that helps and I will make that easier to see in a future update.

Could use some UI Work Nice app. Year selector does not seem to work. Also, it does not follow Android app design standards and is not the nicest looking app. Cool overall though.

CAT-TASTIC This app radiates splendifarousness. Anyone who chooses to download this app shall be rewarded with a concise, easy-to-use, FRC tracker. Let us all rejoice
