YAY PONIES!

Every time that we've used encoders for swerve drive, we've coupled them with a 360 degree potentiometer for initial calibration. This way, you (almost) always know where your wheels are pointing and how much you're slipping.

If you throw a well-calibrated Gyro into the mix then you've got field-oriented drive + drift compensation!

We've also had great results using the US Robotics encoders included in previous KOPs. One for steering, and one for drive.
