While trying to calculate the speed of my rover (seen in previous post) with its four different sets of wheels, I did the following:
Diameter X RPM = too low to be anything
Diameter^2 X RPM = too high to be legal
(Radius^2 X Pi) X RPM = WTH AREA?
Then that's when I realized (that I was failing in life and) it's just:
(Diameter X Pi) X RPM
So much for taking Geometry.
Either way, my rover's top speed (with its largest wheels) is 1.3 MPH. For comparison, my robot goes ~ 3 - 4 MPH. And by my calculations, Adam's robot's top speed (with its only wheel set) is 1.4 MPH. Darn. Now we just need a race to confirm this.
I would like to say thanks to Google for calculating all my conversions.
