In case you were curious, Ohmer's OPR of 74.6 would rank either 24th, 27th, 32nd or 37th in the four (99 team) divisions at the World Championship. The average OPR for the divisional top 8 teams is ~114 and for the divisional top 24 teams is ~98. We would be competing to get a late 3rd round selection with a 95%ile robot in the playoffs since our unit will become an ~70%ile unit at the championship. As stated earlier, let's take pride in the accomplishments of Team 86 in 2014. Additionally, let's aim for the stars and produce a 99%ile robot next year.
About a century ago, Mark Twain said," There are lies, dambable lies, and then there is statistics". With two statics known as "OPR" (offensive power rating) and "CCWM" (contribution to winning margin) one is able to predict a winning alliance in the playoffs roughly 95% (19 of 20 matches) of the time at Ft Lauderdale. In the elimination rounds it correctly predicted the winner 83% (78 of 94) of the time. These results are statistical data from a matrix analysis of match score contribution by each robot. This is a useful tool to pick alliance members who give us a best change to win. For example, five 28 to 39 OPR picks went unselected at South Florida while lesser bot were picked. Scouting and OPR go hand in hand in building a winning alliance. Six weeks of data show OPR successly predict the elimination winner at about an 80% with a +/-9% rate and about 90% in the playoffs.
Team 86 finished in 2nd place on a tie breaker (11W-1L) at the FIRST Robotics - South Florida Regional. In the playoffs, we finished 3rd after being knocked over on an uncalled penalty. Our overall ranking for offense (OPR) is 148th of 2,729 robots at 74.6 points or the 95%ile level. Our overall ranking for win margin (CCWM) is 98th of 2,729 robots at 80.8 points or the 96%ile level. This is Team Resistance’s highest ranking since Ed Law began publishing data in 2009. Additionally, the team received the regional “Engineering Excellence” trophy. You students produced an outstanding unit in Todd’s garage which competed admirably against teams with more resources. The earlier problems of burnt out electronics/controls at the Orlando regional were not repeated this time. Congratulations on producing our best robot in 8 years (2006 - Aim High - Poof Shooter) which was the last time Team 86 had a top 150 unit. An average robot in 2014 scored ~25 pts while an above average (75%ile) bot scored ~43 pts. It is great to be able to state that Team Resistance made a superior robot in 2014. Set your goals even higher for next year in order to produce a 99%ile (spectacular 100+ pt) robot.

WOW. What a rollercoaster weekend!
We got there with a perfectly functional robot.
On Thursday we found that the game field officials had overinflated the balls and at least 8 teams could not play or had trouble playing due to balls not working in their mechanisms. After much ado we somehow got the officials to make the balls match the game rule specs....after modifying our machine to make it work as well as we could with oversized balls. This machine modification caused us to miss all of our practice rounds.
On Friday we had the robot ready to run. We took OHMER out to the field and proudly placed him in position for a single ball autonomous run. When the power switch was closed, smoke gods began to escape. Turns out that the new battery has its Anderson power pole connector wired backwards. The resulting smoke damage included the 12-volt-to-5-volt power converter, at least one C-Rio plug in card and plug-in module, and the Wireless Router.
Robert (and Blake?) ran down the street to the parking lot a couple of times to get replacement pieces-parts off of the mechanum wheel prototype stashed in the trailer. By the end of the fourth round we had OHMER patched up and began to make up for lost time in the fifth round.
At the end of the day, despite having one alliance member that just held onto the ball, we had climbed up the ranking ladder from ~55th palce to to #30 by the end of the Qualification rounds. With such a horrible start, it was no surprise that we did not get chosen for the Elimnination Tournament.
Despite all of the trials and tribulations, OHMER and the Drive Team did very well once the bugs were fixed. You can see this for yourself on the online videos from the Orlando Regional Website.
The game play was extremely rough at the Orlando Regional. Robert and Frank commented that we would be better prepared for such shennanigans if we had the big CIM motors back on the drive system. When we left Orlando, we took the drive motor-gearbox-wheel assemblies off (per the rules) and will disassemble and clean them here at Chaos Central. We will replace the steel wheel drive shafts with aluminum shafts with hexagon cross-section and replace the wheel hubs with hexagon-hole wheel hubs. This will allow us to quit worrying about the setcscrews holding the keys and wheels on the shafts properly while simultaneously dropping one entire pound from the robot weight. We will re-assemble the gearboxes with the big CIM motors and lighter-weight parts.
Hopefully everyone will be signing up for the Ft Lauderdale Regional coming up in two weeks. There will be a new post here on the website soon with full info on the trip. PAY ATTENTION!
The referees this are racking up the penalities. Basically the average game score is inflated ~34.2 points or roughly 6 points per team. This is a significant impact since the 50%ile score is 21.2 OPR unadjusted for penalties. 70% of the games has the potential final score skewed by a 20-50 penalty.
TEAM RESISTANCE TEE SHIRTS WILL BE HANDED OUT PER PREVIOUS GUIDELINES (two shirts per active member) AT CHAOS CENTRAL FROM 7:00 PM to 9:00 PM
If you ordered additional tee shirts for family members, they will be $7.00 each. Bring exact cash or a check (Payable to TEAM RESISTANCE Inc. for extra shirts, please.
IMPORTANT STUFF! LUNCH!! EVERYONE READ AND HEED!
The standard lunch situation at the Orlando Regional is usually crowded and hurried and pretty much inhales audibly. This year plan for it to be much worse because unlike previous years at UCF, we were there during spring break and the normal resident students were mostly absent. Lunch was slow and crowded then. This year our competition is not during spring break so it will be ever-so-much-more-so crowded and slow.
To alleviate having to participate in a 5000-student-lunch-hour in just four local sandwich shops,
Mr. Bailey is coordinating student lunches from outside. YOU NEED TO copy, paste, fill out, and email-forward the following instruction form with your desires.
This has proven in the past the fastest, cheapest, and most likely method to get you fed and back into the stands before the post-lunch competition begins! Make sure you have cash in hand!

Currently there are 6 robots with OPRs of 100 points or higher of the 1,000+ units to compete out of 2,732 for 2014. Make it you business to watch them in a webcast. Learn from seeing the best designs in action. They are as follows:
TEAM OPR Regional/District
1. 1114 159 pts Gr. Toronto East
2. 2485 110 pts San Diego
3. 987 109 pts San Diego
4. 33 103 pts Southfield
5. 3683 102 pts Gr. Toronto East
6. 359 100 pts N. Lights
In general scores are dropping in the games as defenses have improved in week #2. The 90%ile robot has in week 2 dropped ~17% to 46 pts from the 55 pts of week 1. Yet note a new maximum score of 420 points which is a major increase (~45%) over week one's 290 points. I believe this year Ohmer can be a top 10% unit with a 50 point or more average.
