For robotics I decided to write a program that would automatically tune a PID loop (a loop with three magic constants that tells you how much power to give the motors).

Being a high school student who hasn't been taught anything about the theory of PID loops or the right way to tune them, I had no clue what I was doing. So instead of actually learning the calculus to do it, I just made an evolutionary tuner that keeps guessing slight variations of the last-best three constants.

Basically, you press start and the robot spins in circles until you come back in 15 minutes.
