Wind Tunnel

[ultramrw21]

If i remember correctly the SpaceShipOne team mounted the model to the front of a truck to test its drag. Id be pretty nervous to compete against a FIRST team that had to test the drag of their bot.

I think that they need a wind tunnel because they're trying to actually build a wall-bot

Many things are tested by being mounted on top of SUVs and trucks. Testing tensions and forces is possible by (as simply) attaching a force guage - to a string - to the item being tested. You could also mount a video camera up there too. When determining airspeed keep in mind that if you are facing a headwind (which is preferred) you add the speed of the car + the speed of the wind. [ex: 5 mph headwind + 30 mph car speed = 35 mph airspeed] Who needs a wind tunnel when you have the whole outdoors?!

A robot that flies would not be possible to build within the rules unless you are talking about a hovercraft. A hovercraft would be reasonably easy this year if I am interpreting the rules right. The biggest problem (besides not getting any traction, and dificulty of control) would be generating enough air flow to get it to hover. You would need to build an air pump, and it is unclear to me whether that is allowed. There is no way the compressor can handle the volume of air necessary for making a robot hover properly.
