I think we need to introduce you to our friend the regular expression...

Favorite equation for this build season? Torque = r x F. Law of Cosines comes in a close second. Though, I am also a pretty big fan of: Position = ∫∫Acceleration and the cylindrical coordinate system.

[Zuelu562]

C(amps) = V/ohms. Seems to be very useful this year. A lot of people seem to be burning out stuff by putting them to incorrect electrical loads (D-Links, for instance X.X).

Also, R + T + M = (Occasional Lack of) Knowledge

[fox46]

I can't believe I haven't see one of the most important minibot equations!?

Ep = mgh

[548swimmer]

All of the torque and RPM equations for motors and their assorted conversions!

[Foster]

P= ((3.4 * N) div 8 ) + 1

Give N roboteers the number of pizzas P to order

[cire]

Most used: circumference = 2 * Pi * r

Favorite: f = m * a
