Specific exemptions for pneumatic wheels have been listed in the rules before. Off the top of my head, they were in 2012, but also other years.

Motors propel the device in such a way to create a high-pressure side and a low pressure side, wherein air on the high pressure side imparts a non-trivial force onto the robot and the surrounding objects. Conversely, high-speed robots can use this device to intentionally create a higher-than-normal pressure situation on the leading edge of the device, which could then be used as an interference mechanism for any lightweight objects nearby - objects comprising of but not limited to:
  • 4060's latching mechanism
  • Paper airplanes on Einstein
  • The hair that belongs to referees
:rolleyes:

So you're saying we can make the hovervan? Please tell me we can make the hovervan.

We can make the Hover Van.

You kid... Hmm. What is the theoretical maximum force that high-strength propellers can impart within a 30"x30" frame? Would probably be 12" propellers for a competitive robot, given the probable frame needs. Was never very good with fluid dynamics. I wonder if they could lift 20 lbs up about 30 inches in 10 seconds using our battery.

Then we would add a shell in the shape of a van to the top of the device. And yes, you would get your hovervan, paint job and all :D

Rule?

I don't follow?

If a team is really really bad does that make them a pneumatic device because they suck?

Serious question....

The fan is not a pneumatic device
but the tube being filled with air is

right?

No. The pressure would be too low and if the fan is turned off the pressure is lost.

Yes.

You think that would fit in the prematch screen?

Re: Are Fans Pneumatic Devices?
 
Obviously fans are pneumatic devices. The definition of pneumatic is of or relating to air, gases, or wind.

The definition of fans is any device for producing a current of air by the movement of a broad surface or a number of such surfaces.

I see a relation.
