Walking up and down the beaches with a metal detector can net you some cool loot, but its also extremely tedious the perfect job for a robot!
Meet Looty, the loot findin robot: 4 feet long and wide and 2 feet tall. Two rubber tank tracks powered by electric motors. At the front is an array of top-of-the-line metal detectors linked to a computer. When the robot drives over something interesting, it stops, digs up all of the sand 2 feet below it and runs it through a strainer. It then takes whatever is left and deposits it into a locked hopper. The top is covered in solar panels to extend the batteries onboard.
Water proofing and object (read people) avoidance are key in a beach environment.
Add a GPS receiver to it and you can program it to drive down the beach 1000 yards and drive back to where youre leisurely soaking up rays and sipping a Corona.-- thejini, Jun 14 2004 Not a robot, but covers 27,000 square Metres per hour http://www.angus.co...goode/goo300hd.html [Klaatu, Oct 04 2004, last modified Oct 21 2004] Use your sick imagination here http://www.cs.ucsd....al/share/robbie.gif [thumbwax, Oct 04 2004] You may want to include beach towel avoidance. Or not.-- Worldgineer, Jun 14 2004 Not a Speedo. An eye patch and a parrot.-- phoenix, Jun 14 2004 A Speedo? Is that like a pant?-- simonj, Jun 14 2004 (Imagining Lost in Space's Robbie The Robot walking along a beach in pair of speedos) Sexy.-- spacemoggy, Jun 14 2004 DANGER MRS. ROBBINSON. DANGER-- 2 fries shy of a happy meal, Jun 14 2004 psst, [Blissmiss] - I think [simonj] was questioning your use of the singular 'speedo'.-- spacemoggy, Jun 14 2004 I think [blissmiss] is right... I think it should be singular... and usually avoided.-- zigness, Jun 14 2004 I would add something to avoid picking up clams (unless you want clams).-- notexactly, Apr 22 2018 random, halfbakery
