Pablo Odysseus is an autonomus bot that rakes art in the sand
While walking along the shore, the footprints you leave behind are mildly interesting, and perhaps you might go to the effort of scraping a pattern in the sand if you were feeling rather creative. If, however, you wanted to make drawings on a massive scale, Ulysse’s robot “Pablo Odysseus” looks like an elegant solution.
The Arduino-powered rover uses two wheelchair motors to propel it along the beach, as well as a rake to leave a mark as to where it’s been. Navigation is provided by a GNSS receiver (a more general term for “GPS”), a digital compass, and an odometer set up on each of the motors. Meanwhile, USB dongles enable it to communicate wirelessly with a smartphone and laptop.
