My mentor told me that if you can't get to the top row, you shouldn't move during the autonomous (this is not what I'm thinking).

To do nothing means leaving another tube to litter the field and possibly get in your way. I'd rather spend those 15 seconds earning two points than doing nothing. Maybe I just don't get it?

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

The tower races can be scored manually if needed. However, because of the way such points are entered into the data base they do not wind up in an easily identifiable place. I forget exactly where they go, but there is a place for manually scored points. They will not show up in the minibot points column. They will be included in your final score for the match and will be used in your ranking score etc.

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.

Our guide system involved 2 rods going up and holding the minibot. If you have a similar system that keeps the minibot oriented correctly WHILE it's moving up the tower, you're going to need to cut it down so that your minibot is not in contact with the upward pole after it gets above the deployment line.

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.

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.

At FLR, the dominant robots could score logo pieces quickly, consistently, and often.

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.

I think this was the opinion I expected to see, but what I wasn't seeing on the rest of this thread. I assumed the autonomous would be least important, probably because that was how it was in the past. I didn't think about the amount of points you could get from that.

Paul Copioli 08-03-2011 06:40

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.

There is the JVN guy that keeps a blog during the build season. He had a really good post about this exact subject a long time ago.

While we didn't make a nice table like John did, we did pull up the 910 IRI video during week 1. Thanks again Foley for proving it could be done back in 2007.

I sort of disagree... I think it was the newness of the drivers getting used to how crowded the field was, and even through week 3 & 4 you will have plenty of teams that have never driven on a full size field with 6 robots & tons of tubes. My suggestion was simply because I believe the INTENT of the rule was to keep you from interfering with robots in the lane, but even when there is no robot, there are penalties, and there are just SOOOO many penalties this year.

Teams should be discouraged from just throwing tubes wildly that could take out the scoring equipment. A yellow card might do the trick.

They were giving out yellow cards for humans throwing tubes... ours unfortunately got one, as he was trying to throw across the field and accidentally hit a nearby robot trying to score in its zone :(

I believe its just that in week 1 logos did not score as much as minibots because sooo many teams had so much trouble with scoring logo pieces. Whether it was driver inexperience, robot issues, design flaws, or just shear field traffic, many teams chased tubes around the field and spent so much time just trying to score a single tube. My guess is that many of them drastically underestimated the difficulty of scoring on the high pegs, and went for "doing everything", rather than just getting good at the middle or lower pegs. Granted the really good robots could do it all, but I think too many tried to do it all, so logos were just not as common as originally intended perhaps. I think this will improve as drivers learn to drive their robots and teams fix all the bugs/tolerance issues. But it was very clear which teams either finished early or had second robots to get their drivers practicing on, and which teams didn't. I think there were maybe 5 robots that I would have called "good" at scoring logos at FLR.

pfreivald 08-03-2011 11:33

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?
 
Observations:

  • Logo formation is a must at 2x points, one team had 4.
  • Don't be afraid to try autonomous, it is difficult and even the teams which appeared to have it down missed, but you never know.
  • Try only 2 teams placing on the rack with one team retrieving tubes and placing them at your end so your scoring teams may use and harder for opponent. Some robots were wandering way too far to get tubes.
  • 3 teams attempting to score appear to just get in each others way.
  • If a team cannot score then block tubes, get in the other teams way but stay out of their end, penalty.
  • Do not get a tube caught on the mini bot tower, penalty, found out hard way.
  • If your alliance has a mini bot then make sure you attempt to get it up the tower as it is a tie breaker against a team with out a bot, we found out the hard way again with a 50-50 loss, ouch.
  • Some teams "appear" to take too long trying to hook a poorly picked up tube instead of dropping it and picking the tube up properly.
  • Practice throwing tubes! The round ones roll to your end if done properly and poorly thrown ones hit the judges on the sidelines and are dropped nice and close for the other side.
  • SECURE BATTERY, often said but it happened again.
  • Loose wires, secure so they won't come out when the robot is hit.

Judges shouldn't be putting tubes back on the field. It might be OK for referees, but I'm pretty sure it is supposed to be the field reset people putting the tubes back into play.

Grim Tuesday 08-03-2011 20:27

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.

I saw quite a few tubes fly off the field at Kettering, and I was only there for about 7 matches. It seemed like refs were putting quite a few back in, though I could tell that it was an inconvenience for them (they were blindly putting the tubes back in play while still keeping a close eye on the robots).

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

There is only one case where this advice is useful - One of your alliance partners CAN score it on the top row if you leave it for them. Otherwise, it will be better to hang the yellow tube for some points than to leave it around to get in your way.

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

Paul,
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. :)

The double uber-tube by 148 was in the finals I think.

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.

GaryVoshol 09-03-2011 06:53

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.

Having three ubertubes in a match isn't something we'll need to wait until CMP to see -- indeed, it happened at the Granite State Regional in week one multiple times by the winning alliance of 175, 1519, and 176. What I was hoping to see was 6 ubertubes scored in one match; GSR came close with 5 ubertubes in Semifinal 2-2.

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.

I wonder how long it will be until the video is featured on youtube as its own feature? Last year, Dean Kamen was kicked at point blank range by a soccer ball from a 1519 kick that had enough oomph to have flown the length of the field. Team 1902, Exploding Bacon, put it up on youtube pretty soon afterwards: http://www.youtube.com/watch?v=OnE0j69_gYk

Jared Russell 09-03-2011 09:16

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!)

I'd like to see that ONLY if it's during an Elimination round, or the other alliance robots are not designed to hang tubes themselves.

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...

If someone told me they had a three tube auto and they could sufficiently demonstrate that scoring at least two of the tubes was very guaranteed, I would gladly run no autonomous mode for that match.

Mark McLeod 09-03-2011 09:43

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.

I see wisdom here. :cool:

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.

The flip side of this is, if your autonomous isn't any more consistent than the hypothetical 3 tube auton...
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.

Not really. If the other two robots simply drive forward a set distance and drop their tubes in front of them, the third "triple-scoring" robot would simply have to turn to pick them up.
I don't know that we'll see it at CMP, but offseasons? Not impossible.

We run into multiple instances where we're comparing two teams with almost identical robot performance, all the time. In these scenarios, we try to pick the partners who we think will "play smart" and do what they can to help the alliance.

This happens more frequently than you might imagine.

We do this too, with close performance robots, but your "almost identical" robots won't be one of those who stepped aside to let you shine. They will have fallen in the scouting ratings for almost all other teams.

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.

Teams who showcase individual strategies/features at the expense of their alliance's success always plummet down our pick list. In fact certain teams who have consistently done this year after year are no longer even considered for our pick list.

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.

Absolutely agree with the points that you brought up in your post. I get irked when a team decides to throw a match for the sake of putting their own goals ahead of their alliance partners. This is mainly due to my experience (in Atlanta 2009) that cost us being undefeated in the qualifications. I understand why they made the move they did and it worked for them in the end, but it obviously the rest of the alliance.

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.

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.

In the scenarios that you, Karthik, and John are describing - are the teams always aware that they are putting their desires to showcase their robot ahead of the success of the alliance or, are they sometimes ignorant in making these decisions and capable of improvement or show improvement under the guidance and experience of savvy alliance partners?

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

Actually in my case (one mentioned in my post) the team came out and told me they were going to throw the match. All water under the bridge now, but at the time it was difficult for us to swallow.
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.

I don't think this is a very smart thing to do. Just because a team is out of it in terms of getting into the top 8 and thinks it is important to showcase their skills doesn't mean you shouldn't think about picking them. A team that does this just wants to play in the elimination matches and win, so how does that make them a worse pick for the elimination matches. It isn't like they will do this during the eliminations so why take them off of your list?

If they are putting their interests ahead of the interests of their alliance partners, I have no interest in picking them.

If none of the three are anywhere near the top 8, they won't need to do anything out of the ordinary to attempt to show off.

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!

What I'm wondering is - would this topic be a good workshop or even Championship Conference level presentation to develop? I think there's a lot of information/training opportunity for what it takes to be valuable to an alliance here.

Just a thought,

I don't know that we'll see it at CMP, but offseasons? Not impossible.

You don't even have to drop. Pushing a UT to the right place for pickup could do it. In either case, the commentary regarding the relative reliability of auto routines would apply. Giving up a certain 4 or even 2 points for a possible score by a single 'bot is akin to the slam-dunk. The term has come to mean a more reliable process than the actual on-court results. Showing off is best reserved for a show and not a game.

Showcasing your robot in an alliance...hmmm I like the sound of that. It would definitely be beneficial to teams that are new to FIRST and would go hand-in-hand with alliance strategy.

We've found that teams who are not willing to listen to a smart strategy during qualification matches are very likely to not listen during the elimination rounds. Simply put, these are teams we don't feel comfortable working with.

I guess I can see where you are coming from on that now. But in my opinion, that doesn't mean that a team is not willing to listen to a smart strategy its just a team that is willing to take a risk in the hopes that they will make eliminations, but thats my opinion. In my experience I don't think I have ever had a team that didn't cooperate with our strategy if we were alliance captains. For us it wouldn't change our pick list in either direction but I could understand why it would change yours and you can't argue with your results.

This might mean something coming from a team that wins something once in a while. But from you guys? Pshaw.*

*NOTE* In no way, shape, or form do I condone throwing matches, nor have we ever done it. This post is written in purely hypothetical terms, so that those who do not understand throwing matches can understand. */NOTE*

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.

PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE don't use sharpie!! Buy or borrow some white fabric paint!! Its IMPOSSIBLE to read black on blue from the stands, and often hard to read black on red.

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!

JaneYoung 10-03-2011 13:26

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.

I also agree with this. Although it may look visible when viewing up close, it is usually quite difficult to see from the stands. A black permanent marker may work as a quick fix, but try to use contrasting colors for better visibility.

We've typically found that white works very well.

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.

We verified this by putting our sensors right over the black tape during the practice day -- sure enough, it was triggering them!

Our autonomous worked fine on the practice field (which did not have the black tape), and fine at home, but would not work on the field itself.

Just another heads-up that that black tape is certainly an issue when programming for branching. I have attached a screen grab from the Chesapeake Regional Webcast which shows the black tape at the Y.
