The robot may have devices to remove the opponent from the square except any projectiles tethered or untethered, flames, sharp objects, and magnets. Pneumatic devices are not allowed." A pneumatic device is defined as: of relating to, or using gas (as air or wind). A vacuum is clearly a pneumatic device thus if LASA is really using a vacuum than it is illegal according to the rules that were distributed in August. If I'm missing something then please enlighten me, but otherwise I don't think vacuums should be allowed and anyone using them should be disqualified... of course knowing LASA they'll just build something ten times better anyway

1. Pneumatics is the use of pressurized gas to affect mechanical motion.
2. Any device which generates or is powered by compressed air
3. Any of various tools and instruments that generate and utilize compressed air.
4. A device moved or worked by air pressure.
A vacuum pump clearly fits all of those definitions… Furthermore if you got to Wikipedia: http://en.wikipedia.org/wiki/Pneumatics and click ‘examples of pneumatic devices’ vacuum pump is clearly listed at the bottom.

I spoke with an associate professor at our state college at the begining of the season who said that a vacuum is a pneumatic device so we took it off our robot early on. I'm not going to deny that being allowed to use them peeves me a little... oh well... nothing we can do about it I guess.
Starapollo1 wrote:That's still a little frustrating... I'm with Monger on this one. If they didn't mean to outlaw vacuums they shouldn't have blatantly said “No pneumatic devices.” My team really wanted to use vacuums but didn’t because the rules clearly stated it would be illegal.
MoneyMonger wrote:Oh that makes sense; I guess I was just over thinking it a bit! I do have one last question though, if you’re willing to answer it. Would a dedicated closed system (vacuum pump; more specifically, a diaphragm pump) be illegal? That is, compared to fan units.
