  • Sample RobotC Graphical programs?

    Is there a source of pre-written RobotC Graphical programs available from which I can learn and therefor teach to my Civil Air Patrol Cadets?
    Specifically, (for now) I am looking for guidance to get ClawBot to smoothly follow a line.
    The curriculum downloads that I find appear incomplete and not entirely helpful. Is there a source that I am overlooking?

    Regards,

    To smoothly follow a line is actually pretty difficult, easpecially in the graphical version of ROBOTC. But if you go to file --> sample programs you'll find plenty of examples including a very basic line tracking program.

      As mentioned, making it smooth is hard. Here is what I would do, depending on line width and on how sharp the tape line can turn (assuming no tight turns here, no T's, etc.):

      3 sensors

      If the central one and a side one are both on the line, veer more slightly.
      if only the central one is on the line, go forward.
      If only a side one is on the line, veer harder.

      Ultimately, much of the problem relates to how sharp a turn the line could take. If it can turn sharply, then the robot has to make quick, little adjustments, which will make the follow less smooth.
