about getting sand mixed up with Lego gears, axles and motors.


I'd say use sand, just don't use tracks because they clog up when turning.
Use a four wheel chassis for stability with central pivot. Power only the
front wheels and then independantly so you can steer. The rear wheels will
then follow automatically although turning will have a limit unlike tracks.

Why even use sand at all?  If the challenge is for mine detection, use a flat
surface, and have the mines be attached to the underside.  This allows for very
simple drive systems, and no surface clues to show for the mines, or possible
bias by the miners, who might pile more sand over mines for some competitors.

(...) Why underneath? A flat surface with paper discs taped down to represent mines would be fine. Then the light sensor could be used to detect them. After all, the point is really to find them without rolling over any while searching. You'd need (...) (22 years ago, 13-Jan-03, to lugnet.robotics)
