Gas Shock Legality?
In the manual, <R72-I>, seems to allow for the use of gas shocks so long as they are safe. This implies that they are legal for this game. But, <R01> restricts the methods of stored energy and does not mention gas shocks specifically. Our strategy depends on compressing gas shocks prior to match start; holding that energy throughout gameplay and releasing that energy by a motorized latch system to lift a considerable section of our robot during the Finale. Is it legal to store energy as a compressed gas shock (or multiple shocks) for use later in in the end-game?

Re: Gas Shock Legality?
Without a lot of years of experience, I would say yes, because it has been allowed in the past.

Re: Gas Shock Legality?
You will need to ask the Q&A for an official answer, but if I were laying odds I'd say you've got a 90% chance of being legal. Gas shocks are no different than any other spring or elastic system, and there's never (that I'm aware of) been a prohibition on using those.

Re: Gas Shock Legality?
Short answer, as far as I can tell the answer is yes. Unless you can find a rule that explicitly forbids them they are legal. I believe they would fall under the same category as springs. (In cases where I need force and not velocity I prefer gas shocks for safety reasons) This is my interpretation and I would really appreciate if someone with more FRC experience (preferably on the inspector side of things) would confirm this interpretation.
I happen to agree with you based on my reading of the 2010 rules but have to argue with how you came to this decision. Past years rules have no bearing this year. |

Bill, I would Q&A this if I were you. Asking if they are specifically not allowing energy to be stored in gas shocks |

The GDC has posted multiple threads that verify that gas shocks can be used. Just be aware that lifting a "considerable section" of your robot implies a considerable stored energy and will attract considerable attention from the inspectors in regards to safety. In particular, please insure that you have solid engineering data that the shocks are being used within their specifications and that you have an absolutely fail safe method of insuring the safety of all in the pits, at inspection and going onto and off of the field.

Definitely hit up the Q&A with the question, though. |

Can someone please bring this up in the Q&A system or point me towards an answer already posted in Q&A? We're planning on using a gas strut on our machine this year and it would be compressed (Storing Energy) at the beginning of a match... |

<R01> does explicitly permit the deformation of robot parts (part D). See also Team Update #7 further addresses this... Regards. Mike |

Re: Gas Shock Legality?
I can't quite convince myself that compressing a gas is a close enough equivalent to deforming a solid for <R01> to permit it as a pre-match source of stored energy. This one will definitely need an official ruling before everyone can agree on its legality.

I would like to think that the ruling would be made with the same logic this year but I can't be sure... I guess we'll move forward until we hear otherwise. |

<R01> does not specifically allow compressed gasses (other than the pneumatic system) to be used as stored energy. Personally, I see no issue with using it as long as it was legal and safe. Mike, If you believe that compressed gas shocks are allowed to store energy at the beginning of a match, please show me the exact rule. TU#7 does not directly address compressed gasses at all, just the safety of stored energy. Last edited by Daniel_LaFleur : 12-02-2010 at 16:31. |

As you well know by now, <R72> part I is the only place that gas shocks are mentioned in this year's rules. They are not prohibited either. That makes them a non-pneumatic robot part which, in my opinion, may be deformed IAW <R01> part D. This is my opinion. I am not a member of the GDC. I'm going to stop typing now... Mike |
