When is a fan a fan?

[jnicho15]

In regards to the 2016 rules, is there anything that says one cannot attach a legal motor to an EDF unit (http://www.hobbyking.com/hobbyking/store/__4242__EDF_Ducted_Fan_Unit_7_Blade_4_5inch.html) and use it as a fan for cooling/inflating?

In the past devices have been defined by what they are marketed as. If you can produce packaging for a push button calling it a light switch then it is a light switch, if the packaging says push button then it is not a light switch.

I do not recall a rule saying you cannot use a legal motor to spin a fan blade assuming it is recognized as safe.

Things like this have been allowed in the past, as long as the inspectors deem it safe. 2009 was a fun year for fans (heh), since the limited traction from wheels made thrust provided by fans actually significant. Examples: team 45 (http://www.chiefdelphi.com/media/photos/33166),
team 1771 (http://www.chiefdelphi.com/media/photos/33650)

Also, some cool fan based manipulators were used in 2010, where you weren't allowed very much contact area on the game piece (soccer balls). Team 25 (http://imgur.com/a/PshHX), team 706 (https://www.youtube.com/watch?v=X_dnzebFqDk)

If it looks like a fan, feels like a fan, sounds like a fan, and works like a fan, then it's probably a fan. Unless, of course, it's not a fan, in which case it's something else pretending to be a fan. :D

In that case, it's a fan if its packaging says so, even if it's not. (Does that mean you could put a Super Soaker or a blowtorch on your robot if it's sold as a fan or something else legal?) Now I'm wondering, in FRC logic, is this (https://www.vat19.com/item/not-a-cat-cat-the-cat-that-isnt) considered a cat or not? It's marketed as a cat, except it's not...:confused:
