I don't see a single downside to scoring in autonomous.

The problems with the towers are now a known issue and the FIRST technical staff will be working very hard to come up with a solution that allows teams to score without false scores from robots hitting the tower. Some attempts have already been made but apparently were not very successful. The field staff including Scorers, Field Manager, Referees and FTA take this very seriously and will make sure your team gets all the points (and penalties too for that matter) they are entitled too. |

We have a PVC shaft attached to our minibot, that slides into the guide, and the second end of the guide holds it nearer to the tower. I'd try to get a picture, but I really do not have access to our minibot until next monday (or whenever our mentors want to meet to work on the robot again for battlecry. |
Re: Lessons learned for Week 2 Regionals?
This is all really good information. Thanks for starting this thread. A lot is being mentioned on the logo pieces not being a priority. Do you think this is because of inexperience or something else? Do you think this was done intentionally, to make the autonomous and end game( Both a lot of programming), more important, or just the way we are playing the game?

I dont know if the GDC can actually truly anticipate exactly how the game will be played. I have had the honor of speaking to some of the greats Woodie Dave and the like and they always say. Well certaintly didnt anticipate that or didnt think of this solution. I think they make a huge effort to anticipate some general engineering hurdles but they are human and cant anticipate everything. I also think the game evolves over time. This game in that sense is like every other. I think over time the logo scoring will become more important as teams figure out the minibot. It will be intresting to see. |
Re: Lessons learned for Week 2 Regionals?

Minibots are important. Autonomous is important. Logo pieces are important. Do all three well, and you've got yourself a highly competitive robot. Don't, and you've got yourself a robot that might have a place on the right alliance. There's a difference, methinks. |

Re: Lessons learned for Week 2 Regionals?
Scoring an Ubertube on the top row in auton is worth 12 points for your alliance if you are scoring your logo pieces is teleop correctly.
6 points for the ubertube in auton + 3 additional points for placing a logo piece on that ubertube + 3 additional points for the complete logo doubler. Bascially, a 3 point logo piece on the top row is now worth 6 when placed on an ubertube and worth 12 when it is also part of a completed logo. For those counting, a single completed logo on the top row is worth the following taking ubertubes (and their auton points) into account: 0 UT - 18 points 1 UT - 30 points 2 UT - 42 points 3 UT - 54 points I am sure the teams that can do 2 UT figured this out long before the rest of us. |

Re: Lessons learned for Week 2 Regionals?
I know we, for example, had a design flaw on our manipulator -- the tubes were so inflated that our claw couldn't hold them properly, and had difficulty floor loading.
We finally had it fixed by the end of qualifiers, and then were assigned the role of "defense + minibot" for our tournament alliance. |

Re: Lessons learned for Week 2 Regionals?
Make sure that your claw/grabber/manipulator is capable of taking overinflated tubes. We had to make some adjustments, since at FLR the tubes were properly (unlike how we had done them) inflated. IMO the issue with inflatable gamepieces.
On another note, atleast at FLR elims, the game was played the same way I think it will be in week 5. Alliances regularly scored 2+ logos (even at the quaterfinal levels) and then had a full (3 or 4) minibot race. I would watch videos from there, if anyone would upload them to look for strategy. |

The tubes are light and easily float off the field if thrown in at the wrong angle and elevation. |

Re: Lessons learned for Week 2 Regionals?
1.Red Cards are extremely important to look out for and make sure teammates know the rules and how to not get them.
2.Minibots can change a game, end a game, and tie a game. In short their really important! Deployment needs to be on point every time. 3.Defense to me is useless if the robot is super hard to stop, Your more likely to get a penalty playing defense than actually stopping another team. 4.Hanging tubes fast and having an amazing human player is crucial to each other. A great human player can fuel a robot with enough ammo to hang two rows quick. 5. Its Strategy Stupid! un like last year there are multiple places to score in this game, communication, grabbing the right tubes,and strategically choosing where each team hangs and what they hang (so they don't collide and waste time) is really important. I like this game its very interesting to me and all the neat arms, grippers, and minibots makes it very exciting and entertaining. I also wonder what weeks after will be like |

thanks for the breakdown. I bet we'll see at CMP this year an alliance doing all 3 UT. With that and reliable minibots from every good alliance, it'll make for a great Einstein finals with every alliance scoring 100+ for both the winners/losers. Then it'll come down to the minibot race itself. :) |

Are you sure, those tubes might have got some dirt on them, it would be bad to get dust in your eye because of a nice squishy tube. |
Re: Lessons learned for Week 2 Regionals?
Dirt and dust and game pieces aside, I seriously would never consider being anywhere near the field without safety glasses. With up to an 84" wingspan, those robot arms can attack with little notice.

GSR Quarterfinal 4-1: http://www.youtube.com/user/FRCteam1.../6/6FR1aEnhcYA (3 ubertubes in auto by 1 alliance; note also the "ringer" thrown onto a tower!) GSR Semifinal 2-2: http://www.youtube.com/user/FRCteam1.../3/drbPrGJlroI (5 ubertubes scored in autonomous) GSR Final 1-1: http://www.youtube.com/user/FRCteam1.../2/1Bt4JM_FytE (3 ubertubes in auto by 1 alliance; this is also the highest combined score from Week One regionals - 117 to 82) I anticipate that Week Two will probably feature a combined score of over 200 points from either the Florida Regional or the WPI Regional. |

Re: Lessons learned for Week 2 Regionals?
I am hoping to see one robot hang all three ubertubes by themselves at some point. A fast robot with a lightning quick lift and the ability to pick up and score from opposite ends of the robot would need to cover about 100 feet in 15 seconds (to the rack, to tube #2, to the rack, to tube #3, to the rack) in order to pull it off.
It would require optimization and precision at high speeds to a degree that is seldom seen in FRC, but secretly I am hoping that some enterprising team pulls it off :) (469 and 1625...I'm looking at you!) |

During Qualifiers every robot should be doing or improving on what they do. I'd regret it if one team bullied the others into making a Qual into a showcase of a single robot. That's not what Quals are about... |

Re: Lessons learned for Week 2 Regionals?
As long as that's your free choice.
Of course, your robot will be downgraded by most scouters for not scoring during autonomous and you'll drop on most pick lists in favor of the third robot on your alliance who did score... P.S. I'd suggest it be a team choice and the possible ramifications to their season of hard work be presented to them. |
Re: Lessons learned for Week 2 Regionals?

I could see how it would be difficult when you are trying for a top seed and another team wanted to try a maneuver that both of you agreed probably wouldn't work. Whether that be a failed autonomous, or spending 60 seconds at the feeder slot trying to load a tube and keeping that human player from feeding anybody else... There are gracious words to be used that make every alliance member feel valued, and sometimes there are minor sacrifices to be made. Inspire others first, win second. Thanks Mark for the sage advice. I'll pass this along to my team before we compete this weekend. |

Now you're the team who we know is more interested in showing off than in doing what is most beneficial for the alliance to help win the match. People notice things like that. Scouts on 148 like team players, and I assume we're not the only ones. -John |

Re: Lessons learned for Week 2 Regionals?
We take note of anomalies when scouting - i.e. "no auto mode to allow partner to score 3" - in order to make sure they aren't unfairly disadvantaged.
But if a team is skipping their auto to help someone, their auto probably wasn't very good anyway. |
Re: Lessons learned for Week 2 Regionals?

There's two angles to the scenario that's being discussed. Say Team A has a sketchy 3 tube auto mode, while Team B has a rock solid 1 tube mode. I would be very disappointed if Team A ran their three tube mode, as they're giving away the points that would be earned by Team B. Consider the second scenario, where Team A has an amazing and consistent 3 tube auto mode, while Team B has a sketchy 1 tube mode. This time I'd be annoyed if Team B ended up running their mode, costing the alliance the points that would be earned by Team A. What a team does during in a match is clearly their own choice. If a team wants to showcase their own robot at the expense of their alliance, that's their own decision. Do I agree with it? No. I don't think it's gracious to sacrifice your partners' success at the expense of your own. But I also understand the motivations behind it. On a related note, how is a team who decides to showcase their own robot at the expense of their alliance, any different than a team who throws a match for their own benefit? Many teams encourage the first type of behaviour, while vilifying the second. In my opinion, they're both examples of the same thing; a team putting their own goals and benefits ahead of their alliance partners. |
Re: Lessons learned for Week 2 Regionals?

Have to side with you in terms of this type of behavior. Teams should always do what is best for the alliance. This is the type of team that we look for when making our pick lists. |
Re: Lessons learned for Week 2 Regionals?
My philosophy: On the field, play to win, every game, within the bounds of GP.
If playing to win doens't showcase your robot, then what exactly did you build your robot to do?* *Note: This rhetorical question is not directed at anyone in particular. |

Re: Lessons learned for Week 2 Regionals?
My week 1 lessons learned:
(keep in mind that this is the perspective of a Lead Robot Inspector) ------ 1. Get your robot inspected early. Then, you can get in the bypass line and run many, many practice matches. 2. Weigh and size your robot early on Thursday. At the Alamo Regional, two teams did not bother to come over to weigh until it was too late (8:00pm) on Thursday. One weighed in 20 pounds overweight on Friday and the other was 6 pounds overweight. The 6-pound-heavy robot was also 1/2" too wide. PARTIAL INSPECTIONS ON THURSDAY MORNING (weigh and size, and a few other things) is a good thing! 3. Check your Driver Station version. It needs to be 02.27.11.00 or even more recent. If you have an older version, then the field will take longer to connect to your robot, or it may not connect at all. Also, your cRIO needs to be version 28. 4. USE the 12/24 V to 5V converter so that you don't blow up your D-Link router. We saw about 5 teams do this in San Antonio. Some teams went out to Best Buy (or wherever) to buy a new one ($100?), while others borrowed loaners from the spare parts booth. 5. If you don't have your bumpers done, bring materials you need to make them with you to the event. They are not that hard to make. Too many teams are not prepared for this. Sure, it is nice for veteran teams to step up and make these bumpers for other teams, but WHY IS THIS HAPPENING? Bumpers are not hard to make. Three things are needed: 5.1. Get some pool noodles (Walmart or save some from summer) 5.2. Go to Home Depot for some wood screws, staples, aluminum angle, mailbox number stickers and some 3/4" plywood. 5.3. Go to JoAnn Fabric (or some other fabric store) and buy some duck cloth (or something similar). 5.4. Get some sharpie markers if the number stickers don't work for you. I hope this simple things help your team breeze through inspection. Sincerely, Andy Baker |

In most other cases, teams want to showcase their strengths. Depending on the alliance that we are facing I explain the situation and present all of the facts for the upcoming match. At that point, most teams understand what their part in the match is and if anything showcase the ability to work well with others and execute a strategy. |

Re: Lessons learned for Week 2 Regionals?
out of curiosity, how does throwing a match in any way help your team, let alone the alliance? all it does is add a losss to your record. and if you are throwing a match, thats not very GP like!

Hypothetically, Under certain situations, throwing a match can be advantageous. Let's say you're shaping up to be the #7 seed, but you have no desire to be the number #7 seed. Lose a match and you drop out of the top 8. Or, a team is looking at picking you, and you know the pick is almost guaranteed. You sandbag your last few matches of qualifications to appear to be broken, worse than your were before, etc - with the hope that you will be over looked during alliance selections until the team who is "supposed" to pick you, picks you. You're on an alliance with the current #1, #2, or #3 seed, and a team that is close with you is seeded one behind your partner. By playing at a less than maximum capacity, you lose the match. The partner who is a higher seed will drop in seeding, allowing the team that is close to you to move up. I'm sure there are other reasons for throwing matches, but those are the most common ones that I've heard of. Before you think of throwing matches, remember this: If most teams hear that you threw a match to change the seeding, then you'll instantly get black listed on their pick list. I've had teams request that we throw a match, or tell us before hand that they weren't going to play at their full potential, and it's sickening, and I've also had close friends have perfect records ruined by a team that decided they were going to throw a match. It's really not something you want to do, or have your team name associated with. |

I can't tell you how many times our scouters had to pull out binoculars or cameras with zooms in order to figure out what the team number is. The whole concept of "a contrasting color" and the ability to tell teams by their bumpers is lost with black on blue. OK fine if you have silver sharpie or something that will show up, but white fabric paint is cheap & just as easy! |
Re: Lessons learned for Week 2 Regionals?
I saw some bright pink paint being used but didn't see the final product to see if there was enough contrast, this weekend. Maybe outlined in black?
Also, if you buy spray paint and stencils to paint the numbers on, please don't paint inside the venue and be aware of where the paint is spraying beyond the the bumpers. In other words, don't leave you mark permanently on venue property. Jane |

Probably would help if they outline their black numbers with a silver sharpie or something so they don't have to entirely redo their bumper cover numbers.
