Re: Propulsion that does not involve driving wheels
I think the "fan as downforce" concept is fundamentally flawed, anyway.

So you take a fan producing x newtons.

-If pointed horizontally, it could accelerate or decelerate your robot to the tune of x newtons
-If pointed vertically, it generates x newtons of downforce, which increases the amount of friction you get by 0.05 * x (mu * normal force increase). This is far less useful than a horizontal fan.
