Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

I originally was going to purchase the MIT Handyboard but realized that it did not have an analog D/A output.
Thanks for the insightful post John Bond. As for the Axon, does these 55 I/O ports include a digital to analog output? (One which I could get 0-5V output)?
we have not added a closed loop feature like Admin suggests. But we plan to. We will be looping the output voltage back to the Arduino for checking. We will also sense the wheel revolutions per minute and use that data to adjust our throttle signal.
