Re: Pre-filling stored air
It has always been legal to charge your air tanks with one battery, switch to a fresh battery, and then go out for a match. I don't see any ambiguity in that rule this year. Pro tip: just use the battery you used in your previous match to charge up your air.
There are numerous reasons to go off-board if you can create the air capacity needed to pull this off. The biggest one is current draw - with all these high power motors, adding another 20A load to your system is that much more current to deal with and that much more voltage to drop. There's also the secondary concerns of weight and space. Ultimately the only reason to use an onboard compressor is if you don't have space, budget, or weight to use sufficient air tanks for an entire match of air - or if you don't have time to charge your air tank within 5 minutes after a match ends (back to back finals matches). I'm also in support of field-side air. I am aware it relieves one design constraint to do this and thus isn't zero change to the rules, but that's not a good enough reason to not at least consider it for 2018. That restriction isn't the end of the world to see gone. |

As a separate matter, allowing 120V compressors for airing up the robot is just going to add another inspection item, because we'll need to make sure the 120V compressor is regulated down to 120psi so teams don't dump high pressure air into their tanks fast enough to exceed 120psi. |

Also the 1Ah works out to be far less than 1 AH (converted to J) of energy to be used for motion since the conversion is so inefficient. |

If you are smart about how much air you use, having fully charged batteries, and having a design that doesnt run 6 Cims, a minicim and a compressor at the same time you will be just fine. Simplicity trumps complexity when they are performing the exact same task. |
