      Maybe Robomagellan could be viewed as two two contests in one. One,
      steering to one or more goals (way-points) and navigating obstacles.
      Two, finding (detecting) and navigating to a defined object (cone). If
      your GPS is good enough, one might not need the vision, or vice-versa?

      What's more important, the vision or way-point navigation?
      Accomplishing both can be quite difficult (I'm still working on mine).
      Maybe a simpler "entry level" contests could do just the vision? Or
      just way-point navigation?

      I've pondered the best way to get way-points into my 'bot. Just driving
      the 'bot around the course and saving all the moves seems a little too
      much. But simply saving the way-points yourself with another GPS should
      be fine, it's just duplicating the creation of the way-point list.

      I want a hand held GPS that writes to an SD card. Or one might extract
      GPS coordinates from a Google-Earth map. How do the judges make up the
      way-point list?
