Honestly, what people on here say probably won’t matter as much as to what your head ref says at the next event. even if everyone here says it is ok to do (I’m not because I don’t know), ask your head ref before you do it.
Just a thought–the refs might not have a problem, but I rather suspect that the inspectors would give you a tough time about the pressurized helium in the balloons. Now you’ve got a pneumatic system not filled by the compressor…
Not that teams haven’t joked about filling frames with helium before, you understand, but it’s a joke.
Not necessarily. We can connect the compressor to the pneumatic wheels, with a regulator in the middle, and fill this “pneumatic system” with the compressor. This would save labor and be a bit more consistent than the bicycle pump we’ve been using.
Besides, looking through the rules, it seems that a helium balloon would have a hard time meeting the requirements of R75: “All pneumatic items must be COTS pneumatic devices rated by their manufacturers for working pressure of at least 120psi”
So this helium balloon would need to have a working pressure of 120psi.:rolleyes:
I don’t see any issue with the pneumatics rules, as the air pressure is not doing any works - it’s very much like the items under R77 blue box - more similar to an air filled wheel than a pneumatic storage tank. (My opinion; your inspector may rule otherwise.)
If you intentionally detach the balloon, even though it may not be “on the field”, it is still a part of your robot. Once it pokes more than 15 inches outside your frame perimeter, you could draw a foul or disablement under G18.
Is there any point to this? If so, you have to decide whether to put it to Q&A so you have a better idea what to expect, or keep the secret and take the risks of foul and disablement at the first event you try it.
Edit: Further on the non-pneumatic argument - many helium balloons these days do not actually have compressed air - the foil mylar type typically have MUCH lower pressure than you could push with your lungs, just a hair over ambient.
G17 ROBOT height, as measured when it’s resting normally on a flat floor, may not exceed 4 ft. 6 in.
during the MATCH, except during the final twenty (20) seconds of TELEOP where there is no height
limit when a ROBOT is fully contained by the opponent’s COURTYARD.
Violation: FOUL. If strategic, offending ROBOT will be DISABLED.
