2005 FRC Team Update 13
 

The 2005 FRC Team Update 13 is now available on the Team Updates page or directly at Team Update 13

This is just a friendly reminder also to expect Team Updates to be released on Tuesdays by 5pm and Fridays by 10am and also when needed immediately. For faster answers to direct questions you may have on rules please use the FIRST Q&A System.

Re: 2005 FRC Team Update 13
 

Nice to see this update. It clarifies a lot of my questions.

Re: 2005 FRC Team Update 13
 

Quite a few interesting things in this update.

With the special notice, did they mean the operator radio, the robot radio, or both? I assume that they just mean the operator radio (it would be a hassle to be quickly replacing the mounted robot radio right before a match), but it's marginally unclear.

Also, I see that FIRST has remedied the qualifier match scheduling algorithm issue which I was just reading a thread about a few days ago. I'm glad to see that we'll be playing with and against a broader variety of teams this year, rather than the same teams over and over again!

Re: 2005 FRC Team Update 13
 

They mean the radio attached to your operator interface

Re: 2005 FRC Team Update 13
 

Your radio that attaches to your controls at the station is no longer needed (in the station that is - bring it to the event)*. They have this really spiffy looking tower for all 6 radios of each side, and one radio for the field set up at the corner of the field.

I have to grab a good image of it from the camcorder, and then I will upload it to CD, and post a link here.



*Actually, you may not even need to bring your OI radio at all, since you have to tether in the pit. Maybe a sign of things to come next year?
Bring it anyways, you never know when you are going to need it.

Re: 2005 FRC Team Update 13
 

did you see the part about match scheduling?
Good to know for strategy. And props to whoever made the algorithm.

Re: 2005 FRC Team Update 13
 

can someone clarify for me, it's seemed unclear from what i understand so far -

Your robot must physically touch (wheel or something) the target in front of the loading station to be considered "in" the loading zone, and if you do not you will recieve a penalty for getting a tetra off the tetra loader without being within the loading zone.

Is that correct, or am I misunderstanding something?


Also, this update seemed to state that whatever part touched the target must be within the 28" x 38" robot footprint, not extending out in front of the robot to touch it.

Re: 2005 FRC Team Update 13
 

That is correct, given my understanding of the rules.

It's also mildly annoying, as I had the plans all laid out for a flyswatter on a servo at Palmetto. I guess that's the way the cookie crumbles--or is it the way the tetra stacks?

Re: 2005 FRC Team Update 13
 

Wait, does that mean that even if a robot is clearly covering almost all of the triangle, it doesn't count as being in unless some part, such as a wheel, is actually touching the triangle? The situation I've described is shown in my quick paint picture attached below. If this is the case, I'm stupified.

Re: 2005 FRC Team Update 13
 

You got it. Not one of the brightest rules in my opinion, but there it is. Due to the difficulty of enforcement we suspect further changes will eventually happen but that is the way things are for the present.

Don't worry about it too much, it wouldn't be FIRST if there wasn't a morphing rule now would it?

Re: 2005 FRC Team Update 13
 

I'm most confused regarding the use of the phrase in Q&A ID:1715
"we will allow robot-base appendages that are within and remain within the 28" x 38" dimensions to contact the loading zone and be legal"

What about teams who start the match by dropping onto their "side" or "front" as many teams have done in past years? In doing so, they increase their base dimensions to a potential 60 inches by 38 inches. How on earth are the referees going to know if a wheel that is under a 60 X 38 inch frame is within the 28 X 38 inch dimensions?? :confused:

Does anyone know how they will be dealing with this?

-Andrew

Re: 2005 FRC Team Update 13
 

So I got a question almost like the one above, but what the heck. On our robot you cant see the wheels unless your standing pretty much right above the robot. Even if you lie down on the floor from most angles you couldnt see the wheels. Are we just screwed, or will the judges have the common sense to see (or better yet are they allowed to obey common sense? as I am sure all the judges have great common sense otherwise they wouldnt be a judge) that if our robot is on the triangle one of the wheels is probably on it too?

Re: 2005 FRC Team Update 13
 

I just wrote a 500 word rant but 'busy server' canceled that abridged version
I understand that safety is paramount to first, which I guess makes sense in having the loading zone location........ dot dot dot.....(although there are several guidelines for the field attendents when replenishing the loaders :ahh: ).. :]
All of us thought without thinking otherwise that the footprint would suffice as being in the triangle.. having a change that was against .. intuition?.. so late is almost irresponsible.. if FIRST intended for that to be the rule from the get-go.. they should have specified..A normal course of action would be to ammend their previous intentions by allowing what we as a community had believed.. and sense we are all playing with the same rules.. nobody suffers and nobody gains...their solution presently is to either contact with a wheel..(which gives slight problems to robots without turntables) or build something that touches the ground.. which isn't reasonable now with the robots fed-ex'd -- I hope FIRST comes around.. or explains the reason for the rule.. Before you slam the reputation button until your fingers blead give some constructive critisism or thoughts or anything. :) :]

Re: 2005 FRC Team Update 13
 

I find nothing wrong with what FIRST has said. And I'd like to commend them for writing such a solid set of rules.
There have only been a few significant changes, and most updates don't have anything about the game in them. Compare it to previous years and you'll appreciate this year.

Re: 2005 FRC Team Update 13
 

If you have been reading the Q&A system there have been many questions about this. I would like to see the robots only have to break the plane above the triangle with the base dimensions of the robot. This would be harder to enforce.

Re: 2005 FRC Team Update 13
 

I have a REALLY big problem with this rule interpretation - especially coming this late.

Here is the original rule:

<G12> The purpose of the LOADING ZONE is to allow ROBOTS to quickly and safely receive TETRAS without interference while HUMAN PLAYERS and/or field attendants are in close proximity, and then return to play. The LOADING ZONE is not intended to serve as a “perpetual safety zone” to prevent interaction with opponent ROBOTS for the entire match. Tethers, tape measures, long extension arms, and other devices intended to contact the LOADING ZONE to maintain the “non-interference constraint” defined in <G15> while the ROBOT drives around the remainder of the field are against the spirit of the rule and will not be permitted. Such devices must be removed before the ROBOT will be permitted to play in the match. <end of rule>

The rule says to me that we should not have long arms, tape measure, or teathers that allow us to be in the loading zone when we are far away for the purpose of gaining an advantage due to the non-interference contraint. This rule says NOTHING about any 38x28 requirement.

Here is my problem: we designed our robot to require wheelie bars that fold out at the beginning of the match. These wheelie bars are not intended to gain an advantage from rule <G15> - they were designed to prevent the robot from tipping over. The problem is that it is nearly impossible for something within the 28x38 footprint to touch the loading zone since our wheelie bars contacting the side rail prevent us from getting close enough to touch the triangle. Our interpretation was that the wheelie bars to not constitute a tether, tape measure, or some other device to gain an advantage from rule <G15>.

If FIRST wants to make this type of interpretation, they need to do it at the beginning of the process - not once the robot is built and ready to ship.

Re: 2005 FRC Team Update 13
 

Thank goodness they've finally corrected the NYC Crate Arrival Date, we thought (and hoped) it meant 21st March rather than 21st Feb...

Re: 2005 FRC Team Update 13
 

This interpretation isn't going to help anybody. It's an overbearing limitation for the INTENT, which Chris is right in saying is so that the people on the field don't get hurt.

And nobody thinks about how the referees are hurt by this rule as well. As a ref, I REALLY don't feel like getting down on hands and knees to decide whether a tie wrap is touching the triangle. It is a distraction from other more important things the refs need to be looking for, and may even be more dangerous. "Well, the wheels are straddling the edges of the triangle, but that wire hanging down is touching it, but it's not within the 38"X28" dime-----" ::WHAM! Gets clobbered by arm while looking at wheels::

As a ref, I would like to say, "That robot's base is close enough to the loader. I don't care what is touching where, just as long as the arm doesn't fall over and kill me, like it nearly did LAST year."

Re: 2005 FRC Team Update 13
 

I dont understand why every one is getting so upset. I'd like to see more people who are content with the rules, like me and Ogre, to reply with some positive reinforcement. FIRST got it right with the changing of the human player triangle from 36" a side to 48". This was a major problem at the UTC scrimage with scores that were in the 30's originally drop to below ten, or even zero.

Here is what I think FIRST means by the rule of loading zones. Get as close as you can to the loading zone safely, without knocking over the loader, without hitting a field attendant or referee. Then safely take the tetra off the loader while staying there. When you have it you can go score it. Also the reason to get close to the loader is to prevent a defensive robot from attacking you if you were say 10 feet off the triangle taking a tetra. If you get up in there and go through the motions of getting a tetra, that defensive robot will stay away.

The first set of regionals are are important for many reasons. We the players get a chance to see how the game is played and what it takes to win. FIRST gets to see how the matches flow (6 teams this year), how strict to be with penalties, and any other potential problems with RUNNING the event. We get to play, but FIRST has to run it.

I'm sure there aren't a bunch of rule makers sitting in a board room discussing "What rule can we change now to mess with the teams' heads?".

Lets all just sit back and enjoy the regionals!

Re: 2005 FRC Team Update 13
 

Why? Because if you look at the image I posted a few messages back, that robot in the picture is CLEARLY "in" the loading zone from a logical standpoint - it covers almost all the triangle and anyone looking at it would understand that it's "in" the zone and trying to get a tetra. It makes no sense why it wouldn't be. But I guess it is. I mean, is a judge going to lay down on the ground to check for contact when a robot assumes such a position? Heck, you can't even see under our robot that well.

But hey, I've got a simple solution. I'm going to get some brightly colored (non-green) string/rope (see http://www.chiefdelphi.com/forums/sh...01&postcount=5) and tie two inch pieces to the front of the robot, and let it hang. Then when the front of the robot starts to cover the apex of the triangle, the string will touch it. And you know what, I don't see how this is any safer for the field attendant.

Re: 2005 FRC Team Update 13
 

Go through the Q&A system and check yesterdays Answers. FIRST is allowing teams to use things like zipties to hang down to the floor and contact the loading zone triangle. String is always a concern for entanglement...

What first is trying to do is create a black (touching the loading zone triangle) and white (not touching the triangle) situation. How many games have been plagued by rules in the "GRAY" area.

Im sure any team that stradles the triangle as much as your picture will not even get a glance from a ref. They stated in the rules that your robot must make it very obvious(ie. by being right on top of it) you are in the loading zone before getting a tetra.

Re: 2005 FRC Team Update 13
 

but that's the whole point... what does a ziptie do?? if anything it adds weight to your robot.. it doesn't secure the safety of the field attendents.. :confused:
This has been poorly thought through, and it's hard to argue otherwise. I believe there is either a miscommunication at FIRST or there is some intent of the rule that nobody has seen. I wouldn't be surprised to see the rule changed in the next update. :ahh: :D back to class~

Re: 2005 FRC Team Update 13
 

Chris,

I'm sorry I tend to disagree with you on this one. I interpret the original rule as being any extension out side the original starting position is not allowed to be used as the loading zone touching device. Otherwise, how do you set a limit on how far your wheelie bars can extend? And how does an inspector or referee interpret the intent of your wheelie bar? Robot design or strategy intent has to be taken out of the judgment of being in the zone. And as Lavery has often stated about his team following rules, an I agree with his philosophy, use a conservative interpretation of the rules or get clarification before proceeding with a design. Or if you choose to stretch the limits of the rule, have a back-up plan in case of an unfavorable judgment.

Why not simply pull your wheelie bar up when you need to get closer? Our robot also has wheelie bars, but do not rely on them to touch in our design.

I do agree with others that just having the 28x38 robot base hover over the triangle should be enough (too hard for refs to judge contact on low riding robots). I also agree that as a ref, we need an interpretation on robots that start tall, but go down to a 38x60 base.

Re: 2005 FRC Team Update 13
 

That's an interesting problem with this rule. If FIRST indicates that a robot which "falls" to a 38x60 base then gets the 38x60 base to touch the loading zone with, how is that any different from a robot which "folds out" to have a similar size base, as I assume Chris' robot does? I find the two concepts to be pretty much the same thing, so based on their current ruling I'd say that the next logical answer is that robots which fall over cannot use their 38x60 base to touch, making it almost impossible to be "in" the loading zone. Now, common sense should take over here and say that that's ridiculous and pretty much dooms teams who went with that design. But if you allow teams to increase their loading zone contact by falling over at the start but not teams who deploy outriggers, isn't that a bit unfair?

Re: 2005 FRC Team Update 13
 

Can someone do me a favor and copy and paste the entire update in here please? my computer is acting really funny and i cant read the update.

thanks-
Kim

IMPORTANT INFORMATION on: Match scheduling
In the game of Triple Play, because there are 6 teams on the field at once, the scheduling
of matches is significantly more difficult. In addition, in previous years we have noticed
that there have been cases where a team may not be on the field with one team at all, but
encounter another multiple times. In order to maximize your exposure to other teams, we
have implemented a new match-scheduling algorithm. While this algorithm has
significantly improved performance, it does allow some matches to be scheduled
relatively close together. There may be cases where your team has a match that is 12
minutes after the end your previous match. Please make sure your robot and drivers can
be ready to play in this time interval. Although 12 minutes may seem like a short time, if
you are fortunate enough to make it to the finals, you will have only 4 minutes to be ready
to play again. Also note that 12 minutes is a minimum. In general your recovery time
between matches will be much longer.

Question & Answer Items of Note

ADDITIONAL INFORMATION on: Q&A #1715 and #1721
Text from #1715
Yes. After attending and receiving feedback from several scrimmages this past
weekend (2/19), we will allow robot-base appendages that are within and remain
within the 28" x 38" dimensions to contact the loading zone and be legal.
Text from #1721
Yes, however, it is important that it be clearly visible to the referees in order to avoid
receiving a penalty.
During the various scrimmages last weekend, it became clear that robots were having
difficulty getting in the loading zones and receiving and retrieving tetras without drawing
penalties. In order to make this more reasonable for teams, we have decided to broaden
the interpretation of the concept of the robot base, as mentioned in Q&A 978 and 1617.
The referees will consider any item contacting the loading zone triangle, that is
clearly visible and within the original 28” x 38” starting footprint, as part of the
robot base. It is very important, however, that it be clearly visible to a referee standing 5
or 10 feet away. An encoder wheel or caster that is under the chassis may not be visible,

and as a result, may not prevent the team from receiving a penalty.
In addition, FIRST has decided to make the Human Player loading box larger in order to
give the Human Player more room to avoid robot arms or appendages while they are
loading the robot. This “box” will now be a triangle 48” on a side. Human Players are
encouraged to wear helmets if their robot presents an arm or appendage that overhangs
the outside of the field while it is receiving a tetra.
Finally, Human Players should use the following sequence when loading a tetra in order
to avoid a penalty according to rule <G27>:
1) Step into the loading box. To be in the box, part of both feet must on or over the
box border.
2) Load the tetra on the robot.
3) Clearly and decisively remove your hands from the tetra.
4) Step out of the loading box.

Re: 2005 FRC Team Update 13
 

The zip tie will clearly show the referee that the robot is touching the loading zone and considered to be 'in' the loading zone.

The intent of the rule, as Rick stated, it to clearly define what is 'in' the loading zone, and what is not.

To be 'In' the loading zone: The referees will consider any item contacting the loading zone triangle, that is clearly visible and within the original 28” x 38” starting footprint, as part of the robot base.

It's as simple as that. You have to obey the rules.

Re: 2005 FRC Team Update 13
 

I want everyone to know that I am fighting this battle separately with my "insider connections" at FIRST (very loose connections, by the way). My basic argument strategy is this:


1. We (FIRST) provided a kit chassis with a recommended configuration and really talked up how great it was for teams. This new interpretation of the rule pretty much makes the kitbot not touching the loading zone when the base is clearly over the loading zone. Is that the message FIRST wants to give teams.

2. A previously illegal kitbot can add a tie wrap hinging from the front center of the drive base and, as long as it can be seen, it now makes the bot legal. Is that the message FIRST wants to send?

3. Robots that use the unmodified kit design and want their wheels to touch the zone must now go into the zone offset, which is less safe than going in centered. Isn't safety one of the concerns?


I am sending FIRST pictures and examples to strengthen my case. This rule was pretty clear until the latest Q&A shenanigans and the latest update. This has taken a game that will be really exciting to a controversial game decided by rule interpretations.

Re: 2005 FRC Team Update 13
 

well put paul~ thanks for the fight :yikes:

Re: 2005 FRC Team Update 13
 

Thanks for posting that, Yan Wang...

Well everyone can thank me for that update, considering my question was question #1721....

Anyways, I think that FIRST is doing an oustanding job with handling the rules and regulations for this years game. Unlike past years, the rules are clear and easy to understand (for the most part.) I think that their main focus is safety for the human player, field attendants, and referees.

Re: 2005 FRC Team Update 13
 

Depending on how they interpret it, a robot that falls over may have its side considered to be an apendage that remains in the 28x38 base. The location of the side relative to the base has not changed, the only thing that has is the orientation of the base. Now, I'd find that interpretation to be a bit rediculous but I also find the whole rule to be a bit silly.

My bet is that FIRST is trying to come up with a better way to word the rule than they have already. I'm not sure if there's really a good way to do it other than to say that you must "obviously" be in the loading area. I don't think it will be that difficult to determine. Either way my money's on them changing the rule (yet again).

Matt

Re: 2005 FRC Team Update 13
 

Dave,

You hit the nail on the head on this one. I was just coming here to post this, but you beat me to it. By the FIRST interpretation, many past robots would be useless. To further complicate the problem, the fact that you have to reach very high with a heavy object may have lead a lot of teams to do the fall-over thing in order to increase their footprint so they are less tippy. What do they do? It would have been nice to know this interpretation at the beginning of the design period, not after the robots have been built.

The short answer as to why we don't retract our wheelie bars to load: it's becuase they don't retract - they're one-time deploy devices that lock in place once down. We'd add an actuator but that would put us overweight. We would have saved weight elsewhere, but it's a little late now.

Lavery et. al. every year says that we should look at the intent of the rule, use common sense, and not be lawyers. That's what we did. The intent of the rule is twofold: 1) safety, 2) to prevent a robot from dropping an anchor on the triangle and then driving around the rest of the field with the protection of being "in the loading zone". Our design DOES NOT violate the "common sense" intent of this rule. They are simple wheelie bars that move with to robot wherever we go. They don't cause a safety issue and they don't stay behind in the loading zone on a tether while we drive around the field.

Furthermore, rule <G12> states that devices that touch the loading zone must not be against the "spirit of the rule". I argue that our wheelie bars are well withing the spirit of the rule. Rule <G12> then states that these devices will then be ordered to be removed before playing in any match. So, does that mean since our wheelie bars are not within the 28x38 footprint and may touch the loading zone, we must remove them before we can play? That must be true since the "spirit of the rule" has now been interpreted to mean 28x38 footprint.

In case anyone didn't catch it, that last paragraph was a bit facetious. My point is that this is getting ridiculous. I think the interpretation would be much better as:

"Any device made solely to extend your reach toward the loading zone is against the spirit of rule <G12> . Any device that is ONLY used to reach out and touch the loading zone is against the spirit of rule <G12>. Any device that is part of the drivetrain, or extended stability mechanisms is okay, providing that the stability mechanisms are not only used at the loading station."

Re: 2005 FRC Team Update 13
 

Paul Copioli, what are you fighting for, exactly? What do you want the rule changed to?

Re: 2005 FRC Team Update 13
 

many people aren't reading this correctly the major problem is this...
you can be all the way to the wall at the loading zone... and not be in the loading zone(because you aren't physically touching the triangle).. it doesn't make sense.. People would interpret this rule to mean ''clearly be in the loading zone and you will be fine''. But as of right now one can not do that because FIRST has been very straight foward in saying you MUST be touching the surface.(so right now you can go to the boilermaker regional and possibly get penalized over and over... then go to peachtree and not be [depending on how interested the refs are int he rule]) The referees dont' have time to look for this, and the way FIRST has suggested to solve the problem doesn't make it any safer for the field crews.
I think a good way to solve this problem would be " Once a team has stopped over the loading zone, and begin to deploy their arm to pick up a tetra - they may not be touched"
But then I personally believe that there should be interference at the auto- loading zones - and the field attendednts should use common sense when replenishing the supply.
Human player zone positive -- can't be touched negative - takes more time
Auto loading zone positive -- takes less time -- can be touched

Re: 2005 FRC Team Update 13
 

What I am fighting for is simple: If a robot base is straddling the loading zone (see Yan Wang's picture is post #10), then it is obviously in the loading zone and should be allowed regardless if it has a $399 tie wrap hanging down or not. If this rule is not changed, then I plan on putting a hanging piece of Lexan with the following saying in bright safety orange: "Look Ma, I'm touching the loading zone!"

If you can't tell, I am a little disturbed by this latest interpretation.

hey why can't we access the regional events. Some of the site info (pittsburgh) won't open?

Re: 2005 FRC Team Update 13
 

Many people on our team were concerned that our extreme low rider chassis would get stuck on the triangle. As it turns out, we may be lucky in the fact that we "bottom out" on the triangle. We dont get stuck on it, but we do contact it when we drive up on it.

Anyone who is using the kitbot chassis could easily zip tie a skirt on to the front of their machine using the holes in the chassis. People with custom frames, good luck finding a solution at the events. I am sure there will be many people with good idea to help you out. As for the teams who flop over and increase your footprint, I am sure that FIRST will figure out your dilemma.

Maybe it would be easiest if they simply said that "the base of the chassis must be over the triangle" and have the refs make judgement calls on what constitutes the chassis. I am sure this will be cleared up during the drivers/refs meeting on the morning of the first day.

Good luck to everyone!
