I wouldn't be surprised that next year a rule will be created/changed to include one battery on the robot at any time but until then, this is a very grey area. |

Re: 2014 Orlando Regional
R35:
The one ROBOT battery, Anderson Power Products (or APP) Connectors (p/n SB50), the one main 120-amp (120A) circuit breaker (Cooper Bussman P/N: CB185-120), and the one Power Distribution (PD) Board shall be connected as shown in Figure 4-11. Thats the closest thing I could find towards saying that having multiple batteries be illegal. |

Re: 2014 Orlando Regional
The manual does not tell you what you can do. That's why in the Q&A system there are a bunch of "We cannot comment on specific designs." responses to "Can we use a 3/8" bolt for an axle?".

What I was trying to point out to the person I quoted was that just because it doesn't say an item is legal, that it is legal. An analogy to what I was referring to: The manual says nothing about the use of a Globe motor...does that mean it is a legal motor this year? No |

Re: 2014 Orlando Regional
I wonder whether R8 is relevant to the idea of using lead-acid batteries as counterweights or ballast. Is battery acid a hazardous material?

I'd buy it if the mounting solution was considered unsafe, but that's not related to how many batteries are on the robot. Given that it's an ambiguity in the rules (It COULD be legal...but it also could not be, depending on how you read it), I think it's perfectly fair for the LRI to make his interpretation that extra batteries of the same kind as the main robot battery are illegal. What bothers me is that it seems that 1902 was given a signoff/pass by an inspector (maybe not the LRI) that it was OK. Lacking a formal re-inspection process and documentation, that should qualify as a passed inspection. If the LRI disagrees and wants to make them change it after it is brought up, that is also fine. But a T6 shouldn't be given to a robot that had passed inspection, regardless of if the LRI thinks it should or shouldn't have. In my opinion, the entire thing gets hung up on what is or is not an "inspection", what process the teams and inspectors are supposed to go through to get re-inspected, and ensuring that both the team and the inspectors involved are on the same page as to what is being agreed upon. |

Safety is a matter of risk. It's also a matter of balancing that risk vs. need. One battery to power the robot is a requirement (both by the rules and the physical requirements of a working robot); an extra battery doing the same job that a block of metal could do is not. That risk vs. need balance is very different for the first battery than it is for the second. Anyhow, you're speaking more to perceived intent behind the rules than the actual rules as written. What do they actually say? In any other context, if a team showed up at inspection with a sealed canister of corrosive fluid on their robot (one that wasn't somehow required, that is), would it pass inspection? |

This was a terrible situation that happened, and I'm hoping that the rules will be a lot more clear about what's allowed and what's not allowed when it comes down to final matches and configurations. I want to thank the volunteers for their time and effort and it isn't easy having to judge so many matches. I personally know one of them, and can say that he is a wonderful teacher (ret.). All because of him, I got introduced to FIRST and my life has changed since then. Thanks Tom Higgins! ![]() |

http://www.usfirst.org//sites/defaul...list_Rev-B.pdf (Reference the "Reinsp" and "Final Insp (initial)" areas). It appears on last year's form, as well: http://www.usfirst.org/sites/default...nChecklist.pdf I don't know if this section is used religiously, because I've never been an inspector on Saturday afternoon. To me, in general, the official re-inspection should be tracked here, particularly if it's not done by the LRI. |

I also used to be huge into BEST Robotics. It was a good change of pace from FIRST with the limited kit, smaller robots, and games that were a bit more "out there". However, from their first championship event onward I found myself at odds with them more and more, along with the rest of our team. Fields weren't being built to spec, the wireless system had major connection issues, and the build season was stretched all the way into the spring. The whole team was frustrated and felt like we were fighting against BEST the whole time, so we stopped doing BEST. I've enjoyed FIRST a lot, but let's hope things like this year's problems don't become a pattern. I've seen how that goes. |

Re: 2014 Orlando Regional
This one has been hashed out before. The rules also don't explicitly say you are allowed to use aluminum, but I think everybody agrees that aluminum is allowed.
