Re: How many Robots at the nationals had an operational Camera Track Autonomous?

We would add that error to the angle that the turret was pointing (found by potentiometer) to get our final error. And since your PID loop really just needs error, this will skip the need for a gyro to a point, since it won't remember target location.
As I understand your system, your potentiometer is fulfilling approximately the same purpose as our gyro. It is providing a heading of the object that does the shooting. Since we can't use a potentiometer to figure out our robot's heading, we have to use the gyro.
