Because I trust software about as far as I can throw it, and since it has almost no mass, I can't throw it very far.
I know there are a lot of great programmers in FIRST. I also know that teams are always pushed right up to a deadline, and the software teams get very little time to test. I also know a slow arm is a lot easier to stop, and if your arm is going 180 degrees/second and you miss a limit switch for some reason, something is going to break. There are a lot of great teams in 2007 that didn't actuate at anything close to 180 degrees/second. There probably are some that did too, but I'm a lot more comfortable with a slow arm that I can fall back on a human to control, than needing a relatively complex piece of software to control.
Why would you use an encoder? It is simpler to use a potentiometer since your are limited to probably less than one revolution, no?
