Re: Tuning PID Constants Over a Range

A FF + PID arm is much easier to control than one with surgical tubing or a gas shock, imo.

The point that programming can only do so much is definitely valid, I just wanted to point out that arms aren't too difficult, as that's what we spent our season doing
Unfortunately, unlike motion profiling or simple PID, there isn't a nice way to do this on a Talon (right?).
