Velocity (PID) Control (with Prop) for Parallax 12V Motor/Wheel/Position contro

I have the Parallax kit with HB-25s, but I need velocity/speed control, not position control or voltage/power control. Is there an easy way this could be done? The way which I'd like to avoid would be using the propeller to read encoder data from the position controller and have to implement a PID feedback loop to generate an output signal to the HB-25s.

    I believe there are libraries in the object exchange (obex) that implement this already.

    Are you looking for hardware that will do it for you? I'm not sure it exists, but I am hardly "in the know".

    I have used intelligent motors before, you just tell them what to do, and they do the PID control by themselves.
