How does your auto-aim work?

Well, for ours, we use two functions, one for pan and the other for tilt (obviously). For our tilt, we simply use a lookup table based on the camera's tilt servo position, and drive the motor to a certain pot reading accordingly. For our pan, we set a zero position for when the camera is centered to the turret, and the turret drives until that center is reached.

Mogunus, I was wondering what the reason was for having two cameras. Can't you simply get the distance to the goal from:
Distance to Wall = Height from Camera to Light / Tangent(Camera Angle)
and
Distance to Goal = Height from Camera to Light / Cosine(Camera Angle)
Maybe accuracy increases from two cameras, I'm not really sure.
