What's going in your Withholding Allowance?
(I'm hoping this is the correct forum. Please move if necessary.)
I've got engineers here who each want to fill the 40 pounds of withholding allowance with their gear. Each one has valid reasons for their suggestions. So, I'm wondering what are other teams holding out? Thanks, Trying to Help Team 1729 |
Re: What's going in your Withholding Allowance?
We are withholding:
the basket from our manipulator the electronics board 4 wheels (for the spare chassis) 2 reference wheels and their encoders the camera and its mount basically the manipulator group that had the most issues, and the control system for the autonomous testing. |
Re: What's going in your Withholding Allowance?
control system (DS + cRio + power board)
a TON of unneded spare parts lots of little peices of scrap metal, we're underweight and plan to add the extra weight at competition. possible new version of about half our manipulation system grr. -Z |
Re: What's going in your Withholding Allowance?
actually nothing that goes on the robot:D
but we are planning on making a spare Spinning Tube of Death to test with(the motor gets overloaded sometimes when we have alot of balls in their) shorter tubing |
Re: What's going in your Withholding Allowance?
Just a few sensors and some metal braces that still need some finishing. And the driver station. Maybe 10 pounds at most.
We will be bringing probably 50 pounds of raw materials, and maybe 175 pounds of various fasteners (standard hardware) to share with other teams. But that's all COTS stuff and isn't part of our 40 pounds. |
Re: What's going in your Withholding Allowance?
-A piece of body paneling that isn't finished.
-The Camera (we plan to obtain another cRIO with which to tweak programming) -Some odds and ends that may or may not ever touch the 'bot. |
Re: What's going in your Withholding Allowance?
Our whole robot is 38.2 pounds, so we decided to just leave it and cut costs on shipping.
Just kidding...Electro board and camera are left, will ad some more stuff to those 40 pounds... |
Re: What's going in your Withholding Allowance?
Whole shooter tower and turret, all 30 pounds of it.
We are going to mount it on our test chassis and use it to continue software development. |
Re: What's going in your Withholding Allowance?
Ours will pretty much be spare motors, parts, and raw material.
|
Re: What's going in your Withholding Allowance?
School and team name and sponsor stickers....
I think the rest of the stuff we're bringing is COTS, although we might bring the prototype wood chassis if we have room? it's only 18 lbs, and it's slightly entertaining |

oh wait i know: blimp robot! |
Re: What's going in your Withholding Allowance?
For 1618:
-School/sponsor logos -Vinyl to complete the team's blackout look--imagine how they wrap cars, and apply to a robot. -Spare 545 motors with the BaneBots pinion pressed on I'm not sure what exactly 2815 will be bringing. |
Re: What's going in your Withholding Allowance?
We removed our turret with shooter and the electronics to run it (our small electronics board +1 Jag from the side wall of the 'bot)
Not sure what the final weight on these parts was, but it should be well under 40 lbs. We may be adding upgrade parts for the first conveyor (deeper Gates belts to prevent slipping) and the intake roller (investigating ways to make it faster). |

Re: What's going in your Withholding Allowance?
Our robot was built to take advantage of the withholding allowance from the beginning. The drive modules detach, as a unit, from each side of the frame, and the control module is completely detachable, too.
Now we just need to build a dummy chassis to mount the modules on to and we've got five weeks of traction control and driving practice before Seattle. (And, yeah... we could sure use it!) Jason |
Re: What's going in your Withholding Allowance?
We're keeping our control system, part of the turret, and we are bringing in our redesigned rollers.

Re: What's going in your Withholding Allowance?
Maybe its just tiredness setting in... but I was rereading all of the Withholding allowance rules, and being that it is 40lbs of FABRICATED items, this means things like anything in the electronics system (other than fabricated wires), ie speed controllers, camera (w/out mount), cRio, wireless bridge, etc dont count... Am I reading that right? I couldnt find anything in the Q&A or rules to contradict that. (Although I think my electrical team would think it insane to unplug any of the board other than the basic controls to keep!).
We are only keeping the control system basics, likely the camera, our lexan panels to add stickers, and we are going to do some upgrades to our conveyor system. |

Re: What's going in your Withholding Allowance?
We're witholding bumpers, one piece of material from our hopper, & some side panels just so we can get our sponsors & team number on them before the competitions.
All these things together are way under 40 lbs, so we're good to go. :D |

First, consider this Q&A response. For the sake of avoiding word-mincing, note that this question is clearly about "strip[ping] the robot of many expensive but easily installed COTS items before shipment" and "bring[ing] all those COTS items under R35". The answer indicates that wheels removed from a robot are considered COTS, a disassembled cRIO is considered COTS, and a Toughbox assembled per the directions is considered to be COTS. Now consider this more recent Q&A response. I certainly wouldn't consider any part that has been previously installed on a robot to be "brand new", particularly not something that is obviously in a different form factor than typically presented by the vendor (in the case of the Toughbox example). I'd like to call myself "reasonably astute", as required by the second link, but I can't reconcile these responses for the life of me. Help? |
Re: What's going in your Withholding Allowance?
Jason,
Thanks for those Q&A, I had been dilligently hunting the Q&A until the last week, and in looking through the Q&A I figured it would be in Section 8 Fabrication Schedule (since thats what seems to deal with the fabrication period after ship). But it still seems fuzzy: Quote:

Quote:
I guess I thought this 40lbs was simple until I really read/reread it and saw those Q&A posts... I guess at any rate, our cRio weighs 3.12lbs, and the lexan I held back weighs about 2.5lbs, so we have 36.38lbs to go if all signs are pointing at the cRio being included. And Joey, I totally agree... the wheels are definitely not good enough for a vendor to resell after a team has used them, and if the disassembled wheels, bearings, etc are COTS, then why wouldnt the cRio be? I posted questions about the cRio in the Q&A, hopefully we get a speedy response... :) |
Re: What's going in your Withholding Allowance?
The GDC has clarified a bit...I think. While I think this individual response is fairly clear, it definitely contradicts some of the other Q&A posts on this topic.
http://forums.usfirst.org/showthread.php?t=12033 So, I looks like any KOP or COTS item in "out of the box" condition are the only things not counted. This "out of the box" condition is new to me, as Fabricated to me is different than wear and specifying "out of the box" to me excludes both fabrication and wear. The Good: From this post I would include the cRio as not included as long as you bring it in it’s out of the box form. (Nothing else attached) The Bad: Nothing is all that bad. We get to bring in 40lbs of stuff made at any time. The Ugly: No matter when you wired them, any motor with leads/connectors that you bring to the event is counted toward your 40lbs. I know that some teams would normally bring a lot of spare motors. They must understand that this now counts toward their 40lbs. |

Re: What's going in your Withholding Allowance?
It looks to me that if you leave the motors as they were when you recieved them from the supplier, that is, you don't cut/strip/connect the wires or solder to the terminals, and you don't put anything on or make any modifications to the shaft, or add or change any mountings, or anything else, then you can bring as many as you want.
To be safe, you might as well just leave all your replacement parts in the boxes they were shipped in, and don't open the boxes. Getting them prepped will give your scouts something to do on Thursday. |

But what has me confused is why all this confusion, clarification and debate is going on as recently as today. Those crates are gone. It's a done deal. So some decisions have already been made, intentionally, or unintentionally, about a rule that it appears is still trying to be explained. I get heartburn when veteran mentors whom I respect are still trying to figure out what the rules are. And the regional organizers are still awaiting the official marching orders on exactly how and whom is supposed to monitor <R36> once the teams enter the venue. Or not. |

Heh, we'll be apart of that week 1 learning process :ahh:
We're taking our 16-lb electronics board, some spare electronics (4lbs), our shooter (9 lbs), some lexan covers (4 lbs). The rest will be used mainly for accessories rookies should find useful, including #35 chain, 180-lb programmers, 20 lbs worth of code and firmware updates, spare bumper materials, etc. We planned ahead and sent all of our wired spare motors, mounts, and transmissions (etc) in the crate. |
Re: What's going in your Withholding Allowance?
We're withholding our Crab Modules. We're going to set them up on a kit chassis to do some more traction control work, as well as other various work bits.
Oh, also our shooter. Should be fun times. |

Re: What's going in your Withholding Allowance?
Now Im confused:
http://forums.usfirst.org/showthread.php?t=12029 So batteries (even with soldered, crimped, attached, etc electrical leads on them) are considered COTS/Non-Fabricated, but spare motors with soldered wires (often used to help the poor rookie team who didnt know they could burn out a motor) are FABRICATED?? http://forums.usfirst.org/showthread.php?t=12033 It seems to me (like Eric O'Brien stated) that "fabricated" is now being much more loosely interpreted than I expected... I didnt think that scratching the cover of a motor, or using sharpie on it would make it a fabricated item... And then changing the pinion gear does not make it a Fabricated Item?? http://forums.usfirst.org/showthread.php?t=11950 I get the intent of this rule, but I worry about how to enforce it and what it means for those teams who always used to run over to other teams to grab spare material. We always used to bring a box of random raw material to share with teams or use ourselves to the regional, but now Im scared that if we do and it is not in pristine "ordered from the factory" condition, that they will count it towards our withholding weight. Maybe we could petition FIRST/the regionals to let us contribute to a "spares" bucket when we walk in the door and make a pile of extra parts that any teams could use as needed, even if they are "Fabricated" per FIRST's terms. |
Re: What's going in your Withholding Allowance?
cRio board which we made modular for easy removal.
Camera system for further testing on a second robot, Drivers station. Some Lexan panels so they can be lettered and logos applied. Spare wheels. Everything else is COTS. |

The FP 9015 motor with the pinion for the AM Planetary is available as a COTS item:
http://www.andymark.biz/am-0316.html On a side note: for being told not to lawyer the rules, there seems to be a lot of lawyering going on by the GDC. When you have to read "very carefully" what EXACTLY is asked and what EXACTLY is answered and there is still confusion among many veteran teams then something is wrong with the set up. There has to be an easier way to explain things - I don't believe that most of these teams are trying to "break", "bend", "lawyer", or "get around" any of these rules; we're just trying to figure out what the heck they mean. That being said, near as I can wrap my brain around the rules, I believe we are within the bumper rules and the 40 lb withholding allowance. Just my $0.02. Here's to hoping the game is as fun as it appears it will be. Despite these comlications I am looking forward to the game. |

Dave, If you are stating that the correct interpretation to the battery question is that the battery is without leads, you imply that a battery with leads is different and therefore does count toward the 40 lbs. Yes, it is true that a shipped battery does not have leads on it, however, a shipped battery means nothing to this discussion about what is being carried into the event. I can't remember my team ever bringing in a battery without leads on it. I would assume that the GDC does not intend for batteries with leads to count toward a teams 40lbs of stuff, however, most of my assumptions this year have been proven wrong in the Q&A. I guess I will have to wait and see on this one. -Eric |
Re: What's going in your Withholding Allowance?
I guess you could ask on the Q&A....do batteries with leads and connectors attached count as part of the 40 pound witholding?
and the answer will determine how much more electrical tape we need.... |
Re: What's going in your Withholding Allowance?
I think Dave's answer on page 3 pretty much sums it up. If you modify the component in ANY way, it's considered a fabricated part and counts in the 40 lb. limit.
So, hopefully everyone saved those 2007 and 2008 battery boxes and shipped the 2009 batteries in the crate. The students will be busy attaching Anderson cables on Thursday, that's for sure. I'm sure glad we stuck with the FP motor configuration in the KOP. Do they consider sharpie marks as a modification? What about the recommended change to the charger to add the Anderson connector? That sounds like it too is included in the 40 Lbs. Right now, our withholding allowance is about 3 lbs. |

The GDC has spoken and batteries with assembled connectors attached must be included as part of the Withholding Allowance.
http://forums.usfirst.org/showthread.php?t=12068 [rant] I'm just going to come out and say it, I think this is ridiculous. I understand the need to establish a firm definition of what is COTS and what isn't for the purposes of this rule, but requiring teams to rewire all of their batteries at the event seems rather pointless to me. I can say for certain that I am done with this whole "Try to understand the reasoning behind a rule" garbage as there have been many cases this year where my best understanding of the reasoning wasn't even on the same planet as the GDC's. My team is small and now one or more of our members will have to spend the beginning of their day on Thursday connecting lugs and covering terminals in electrical tape. Does this help even the playing field? If so between us and who exactly? I am now beginning to wonder if we need to forfeit any awards/matches from previous years as in both '07 and '08 we brought assembled batteries to the competition by hand. We brought at least 2 batteries to each event which would be in violation of the 25 lb. limit specified by <R41> of the 2008 Competition Manual and <R31> of the 2007 Competition Manual. I guess it's time to figure out where to send these trophies back to :rolleyes: I have seen many veteran teams offering assistance to others (both rookie and veteran) by lending them batteries during eliminations. I sincerely hope that this ruling does not cause a single battery to be left behind because of the hassle introduced. [/rant] |
Re: What's going in your Withholding Allowance?
This is the most ridiculous rule I have seen in my 9 years of FIRST robotics.
For the last 9 years I could walk into the event carrying 10 batteries with leads attached and nobody cared. Now this year suddenly this is different and we need to cut all our heat shrink off our terminated batteries, remove the leads, weigh them as part of our 40 lb witholding allowance, and then spend 30 minutes and $10 of heat shrink on Thursday morning in the pits to re-terminate our batteries? I fail to see any universe in which this makes sense. It's a complete and total waste of time for a rule which is basically unenforceable anyways. How am I supposed to explain to my kids that they can't practice until they re-terminate all their batteries (unless we ship all our batteries event to event...which means we can't practice, and costs a ton of money). Now we're all screwed anyways, as the crates are already gone and there's no way to even comply with the rules without de-terminating all our batteries (Let's not even mention the fact that based on the GDC's response to use the "would I want to return this item and get my money back if I bought it and it looked used" test, our batteries would not be COTS even with the leads removed). There's really no way that teams are gaining a competitive advantage by coming in with pre-terminated batteries. This ruling is absolutely baffling to me. Give me the old rulebook back with 100 more rules any day. At least you could understand them without a law degree. |

Why do we have to ask for clarification for the most basic things, it took a lot of pondering and discussion before anyone even realized batteries might fall into this category, and then it was QnA'd and determined to be illegal. It makes me never want to QnA anything, and just go with Plausible deniability. If this were never brought up and never QnA'd would we have been stopped carrying batteries in? Was this already in documentation/training for volunteers? If so, why were teams never informed? If more explicit rules aren't going to be enforced unless someone asks about them, why even have the QnA system? It seems nothing is illegal until you ask about it. Why does the GDC seem to try to be coy? If their intent had been from the beginning to do this, why not tell us? Why weren't we informed day one what covering a corner with bumpers meant, as it was clearly ambiguous? Why are most QnA's answered in the most noncommittal way possible? Dave, why do you publicly comment on discussion on QnA's warning how they "might" be interpreted, then say that it's of course non-official as it's not a QnA. Why not just say that in the QnA? |
Re: What's going in your Withholding Allowance?
Yeah, I'm getting relatively infuriated at the sheer number of stupid rulings this year. This one moreso than most others, but for years of being chastised not to "lawyer" the rules, and just go on the intent, it seems to me the GDC has gotten very lawyerish this year, and when someone brings up a question about things teams have been doing since basically 1992, why are they suddenly illegal when they clearly DONT give ANY competitive advantage.

Instead of simply saying "Additional batteries do not need to be considered part of the WITHHOLDING ALLOWANCE", why not add "unless your batteries have been assembled into a MECHANISM"? It's not like this is an obscure scenario... when it's obvious that the blanket "yes" answer is incorrect for the device that many teams would consider to be a "battery", it's insane for the GDC to withhold the complete answer until somebody strings together a more precise set of words. It's a huge hassle for askers and answerers alike. If that's the rule, then just lay it on the table. Let's not play games. (Hm, maybe I should see a doctor about those voices...) |
Re: What's going in your Withholding Allowance?
i've noticed the GDC for many years tends to give very non-committal answers, but its been especially bad this year. They always say "we can't make comments on individual robot designs" well, make a comment. Say something like "for this to be legal, you would have to..." or what have you. I'm sick and tired of the guessing game they've led us on. Is this the bumper rule? no. is this? no. why not just say "no. THIS is the bumper rule". Admittedly, there are Q&A askers out there who just refuse to ASSUME some things about the way the rules are written and go based on INTENT. Those people ask so many questions about every permutation of interpretations of the rules and force the GDC into a corner, but the GDC needs to say No, you're being silly. Stop asking questions that you should automatically know the answer to. and when they get backed into a corner like that (say, with this battery issue) they need to say Oh, well, the way the rules are written is NOT what we intended, so here's a modification that FIXES the rule to be the way we intended it.
EDIT: I've been around FIRST since 2003, and every year, they tell us to stop lawyering the rules and go based on intent, and every year the problem seems to get worse and worse. |

Re: What's going in your Withholding Allowance?
The problem is that someone asked a question of the GDC which pointed out how our batteries as we've brought them to the competitions for years are NOT COTS. The GDC then responded based on that knowledge that we can't do it that way based on the way the rules are written. The problems with the rules only make themselves known when people point them out. The thing that has caused all this outrage, is that instead of FIXING the rule to match what the INTENT was, by excluding batteries with anderson connectors attached (like in the battery + its half of connector is NOT part of robot weight rule), from the COTS/Withholding business, the GDC has decided to just respond based on this as is. They could have responded to the effect of: "Oh, you're right, the rules as written DO make that illegal, however, that was not our intent, and as such, we will be releasing a team update in the coming (hours/days/decades) that fixes this, so that the letter of the rule more closely matches our intent." But they didnt.
EDIT: Note: I'm not saying I don't think they will release an update fixing this, but they shouldn't have made a Q&A response which says "Yes, this is Illegal", knowing full well that they're going to release an update that fixes it. |

Re: What's going in your Withholding Allowance?
So, it looks like you have # options of taking your batteries
1. ship them in the crate with no leads on them 2. bring them to the competition 3. with leads on them, and count them as part of your 40lb 4. with leads detached, and the leads having ring terminals on them, counting as part of your 40lb 5. with leads detached, and unmodified leads, with neither counting as part of your 40 lb So, unless you are counting them in your 40lb withholding allowance you must remove the leads. kinda like the battery connector issue in 2004 (i think it was) crimped connectors were not allowed, you had to use the screw on type, lots of folks didn't like that rule, but it was the rule, and if you wanna play, you gotta follow them. |

I would be pleased, however, if rather than arguing the point that batteries + cables should be considered COTS from a legal standpoint, we could settle this from an engineering and common sense standpoint by asking, "What is the point of making teams assemble their batteries on Thursday morning and/or disallowing battery cables assembled in previous years?" The nice thing is that the legal, engineering, and logical common sense arguments all suggest that battery and cable assemblies should be COTS. Jason |
Re: What's going in your Withholding Allowance?
Thanks to the GDC for listening to and addressing this issue. Connected batteries no longer count as part of the Withholding Allowance per Team Update 15
