Sounds like you're making a swerve drive (or similar).

The usual approach is to use a separate motor and rotation sensor (either a continuous rotation potentiometer or absolute encoder), then implement the control algorithm yourself on the cRIO. Check out CD media for some examples of the motors that other teams have used for steering.
