Re: Lessons Learned - The Negative
A more likely scenario for the discrepancy in sizing would be that your robot shifted during shipping. The crates are handled, less than cautiously, and if your robot is bot very structurally sound you could have frame members shifting in the crate. Not to mention, after one regional and countless hard-hits, a frame can easily be tweaked enough to through the superstructure of a robot outside of the box.

-On Curie, the team numbers on the scoring display were completely unreadable. The alliance selection screen wasn't much better (and, in the 87-team division, cut off the lower-ranked teams). -The way of displaying the final score could be refined. It took me until the later part of Bayou to figure out that the red background to the match number meant the score was final. I'm not sure that someone just walking in would figure it out that easily. -I miss the days where the seeding was shown on the screen. Showing sponsor logos is important, but a screen for a few minutes once or twice a day with the information would be great for those of us stuck to the stands. |

A couple comments. I'm not going to claim that I know anything about 3091, but it sounded like in the awards that the kids came from different towns, not different prexisting teams. (Correct me if I'm wrong). As for 2753 and 399, they are from completely opposite sides of the country. The fact that their designs are similer seems random to me. It is very possible for rookies to dominate. 2753 is a good example of this. It doesn't mean they aren't really rookies, it just means that they are good. My team's most successful competitive year was our rookie year. All I'm saying is, just because a rookie is really good, doesn't mean they aren't really rookies. About the mentor involvement. Mentors are crucial. Students need to work to learn, but they need mentors. Kids can also learn by watching mentors do things. (I'm not advocating it, it still teaches kids). Part of the real world is designing things and sending them off to be made. I'll be completely honest, my team had a student and mentor designed swerve drive, we sent away the CAD models and had the parts machined for us, it's just the way it is. I may not have operated a manual mill to make the parts, but I learned about 4-axis CNC machines, which in many ways can be just as valuable. Even if you don't make all the parts on the robot, you can make them for other things like prototypes. I learn just as much from prototypes on manual machines as I do from the computer made final product. Even though the final product is professonally made, it doesn't mean I didn't learn a ton of things along the way. Mentors shouldn't do everything, but sometimes they need to do certain things. FIRST is about learning and if kids are doing everything themselves, then they likely aren't learning as much as they could be. About the rules. If you aren't happy with the rules of inspection, specifically the box, go out and prove them wrong. In Boston last year, my team's robot didn't fit in the box, we got out a measuring tape and showed them that their box was actually 3/8 of an inch too small. We passed inspection. If in fact somehow your robot did grow, and they have an accurately sized box, then that's something you have to find a way to deal with. In the real world, if they tell you to make a 4 foot wide robot and you make 4 feet and 1/8 of an inch, you get fired, if it's 4 feet, you get a raise. The rule book may be long, but someone has to read it. Someone on my team always reads the entire book each year just ensure that we know what we are doing. It's just one of the things that you have to do. All of these things are learning experiences, and honestly, there isn't a better place to learn than FIRST.

Re: Lessons Learned - The Negative
Burt,
First of all, being an FRC rookie does not mean you have never done FIRST before. FIRST runs both FLL and FTC both of which can provide extremely valuable experience to a group of individuals who would still be FRC rookies. Team 2753 was made up of students from last year's FTC Champions so they definitely had some FIRST experience. You can also search around for posts by the user "Lowfategg", he is a student on 2753 and after seeing some of his posts here I am fairly confidant that students did a lot or all of the work on that machine. With regards to mentor involvement, you would be surprised at what students can do when they have experienced knowledgeable mentors guiding them and assisting them. Many of the machines probably have much more student involvement than you think. Having said that there are no rules regarding mentor involvement (other than driving) for a reason, FIRST knows that different teams will choose to run in different ways and has decided not to regulate this. Some teams will have mentors doing all or almost all of the work. Some teams will have students doing all the work with no engineering mentors at all. Most teams will fall somewhere in between. If this is a problem for you and/or your team there are many other Highschool robotics competitions that are limited to participation by highschool students. There are many other topics on this subject already and I suggest you search and read through some of them. Many others have done a much better job of expressing some of the points I am trying to make. I agree with your point regarding the measuring box, it is important for the measuring instruments and scales to be consistent between events. With respect to inspection consistency. It is and always has been the job of your team to insure that your robot meets all the rules and you sign a sheet expressing that to the best of your knowledge you meet the rules as the last part of inspection. Inspectors are volunteers doing the best job that they can. While many of the rules are put in place for safety and to prevent teams from gaining a competitive edge others are put in to ease inspection and to instill good practices. If you have been working with electrical stuff for years then you should know the value of respecting the common standards for electrical wire coloring. Using consistent coloring allows for easy visual inspection of electrical systems to insure that they are wired correctly which benefits both the team and the inspectors. I'm sure Al has some even better insight about the reasoning behind this rule. If he doesn't wander in here and see this I recommend you post in the electrical forum or send him a PM. |

Re: Lessons Learned - The Negative
Just to clarify this, as a member of one of the teams that was involved in 3091, they were a completely new team who consisted of completely new members from two different high schools in Atlanta sponsored mostly by the 100 Black Men of Atlanta. Several Atlantian teams, including us, helped them get started (as in, helped them become an official team, watched over their build season and helped out when possible), but their Rookie All Star award was all due to their dedicated work.

The measuring tape idea from Sgreco is one I wish I would have thought of. Great idea, and I'll be sure to do that if we ever have this problem again. Rookie then, should be defined, and maybe separate awards. Just an idea I'm throwing out. A team with robotics experience against a team with none at all has a large advantage, whether it's FTC or FRC, or some other robotics experience. Those are two completely different types of rookies in my opinion. |

Re: Lessons Learned - The Negative
Foreword: I've posted in a similar style to this post times before; there are very legitimate questions Burt asked in this one. This one is similar to some of the other discussions in construction only.

Re: Lessons Learned - The Negative
I've never seen such a huge FRC crowd be so quiet as the one watching Einstein matches. While I appreciate the game's dynamics, and love how it opened up the doors to creative ideas in ways to do drive systems, it was downright boring to watch. Many of the regulation matches during regionals wound up with clumps of robots and trailers. It was difficult to tell who was doing what scoring, then all of a sudden the group would break apart and there would either be a pile of balls on the floor or a trailer loaded up. Without watching specific bots, it was hard to tell. It was a great game to design for and play though.
The fields weren't completely consistent regional to regional. We gave ourselves a 1/2" clearance...yet the bots sank 1/8" into the regolith, you needed another 1/8" to get over the seams (varying regional to regional), and the Atlanta fields were put onto a soft plastic floor which caused even more sinkage. Combined with another 1/8" reduced clearance to due material fatiguing (yea, our fault), Atlanta just left a bad taste in our mouth. We could take our bot to the practice field and fly around, yet on the Galileo field we kept getting stuck. I understand it was already very difficult to manage field setup this year in this regard, so I'm not sure if there's room for concern or if I'm just venting here. I believe that next year we will have to help this year's rookies along if the field surface is highly tractive. There were several atypical drive train designs (crab/swerve) that simply will not work on carpet due to axial loading ... or at least they won't work for very long. I also expect to see some 2nd year teams with 4 wheels on the corners of their robots wondering why they're having difficulty turning. I also don't think it's a coincidence that there were so many Michigan teams on Einstein this year, percentage-wise. I don't begrudge any of the teams who were there, and I applaud FIRST for finding a format that cuts costs and increases field time. It will be highly disappointing if this format is only used in Michigan again though. I do not agree with the 40-lb allowance for future years. It's supposed to be 6.5 weeks, and it's supposed to be hard for a reason. Of the 3 competitions I attended it was only enforced at DC, and even there it was only sporadic checking. |

Re: Lessons Learned - The Negative
I can respond on the wiring colors. It's happened before, on occasion, that teams have shown up with wiring that is all one color. You'd think that that wouldn't be a problem. But, it is. It's a lot harder to trace. That makes it dangerous. You see, if you wire something backwards and don't have the standard colors, something could easily be destroyed when that isn't caught.

p.s. keep in mind that I am not being biased about my robot, our average scores for Friday, the day we didn't win a single match, was in the 80's (If you disclude the match were we got a DQ due to field issues). Sadly, the alliance pairing consistently gave us a pairing with teams that could barely make a score and against teams that could put scores above that number, it seemed unfair that this happened every match (except for Saturday after the teams had done their scouting). On a different note: BRING DISTRICTS TO FLORIDA!!! It seemed to work great in Michigan, and that would increase the competition of the regional. SPeaking on a purely financial note however, paying for the initial districts, and the state competition might leave our team high and dry for Championships, but it would cost less than two regionals, which we have been thinking about.

Re: Lessons Learned - The Negative
To everyone complaining about the withholding allowance and GP; how is this any different from previous years? We used to have the two build sessions, and teams were on the honor system not to spend any more time than that building things. Now, we're on the honor system not to build more than 40lbs worth of stuff. In fact, at least the withholding allowance can be weighed if necessary; in previous years, it was not possible to tell if a team had spent more than their two sessions working.

Re: Lessons Learned - The Negative
- G14... i agree that im not the biggest fan of it. I know it was in good intentions, but if the real time scoring is going to be off? How can a team be penalized? One match the ending score was 55-32 us. Then after everythig is re scored, it was 122-32. We got a tripple G14....
- I was working the front gate at championships on wednesday night. It really did tick me off when mentors, not students, are yelling at me because we wouldnt let them take 8 people in. or take multiple trips. This has been the way for a LONG TIME. The way i see it, FIRST could easily say "just unload thursday" Remember, most volunteers there wednesday have been working tuesday 7am-11pm and wednesday starting at 7am. READ THE RULES - about the wire colors... hate to be crude, but you gotta read the rules or suck it up. sorry. "i didn't have time isn't an excuse to me... - Practice field was not run properly. Schedualing team for 10-10:10 then 10:10-10:20 does not work. You gotta leave a gap for unload and load. Also seemed to me the volunteers running the fields had no idea what they where doing. Example, letting 3 robots run with over 5 people on the field. I watched 2 kids get hit too. People running the field didn't seem to care..... (i know...first i defend volunteers, then i bash em) - I agree that awards such as spirit, animation, ect. can go friday. That way, chairmans, rookie all-star, EI, and competition stuff cna be done saturday, with time ti spare. O.....speeches should be cut down.... |
