Over at Let’s Make Robots, they have a neat piece up about an Arduino powered robot that can metal detect for you! The TB-007 sports a simple design, hacked hand-held metal detector and a mounted cam so your coin-collecting uncle can stay in the camper while the robot roams for beach loot.

The demo videos are pretty neat. Even though the bot doesn’t have front steering, it does have a “Thingy” that lifts the back of the bot up so the front wheels can pivot the unit in a complete circle.

What would be a great use of this project, is to steal the vacuuming algorithm from Roomba and launch an army of these little guys on a minefield.
