The Roboat is a GPS-guided Autonomous Boat.
Meet the "Roboat" - a robotic boat capable of following a digitized route on a Google Earth map using GPS technology and a digital compass. If only our building had a moat instead of a parking lot, this would be a great vessel for our AVC! Still there could be some lessons to be learned from this project, so check it out.
The Roboat using an XBee, an HMC6352 Digital Compass, an Arduino Pro Mini, and a host of other products to navigate the high seas autonomously. It uses the XBee to link to a land-loving PC and relays it's coordinates back to the computer. Check out the above video for a demonstration or check out the website to see more details about the Roboat. Happy sailing!
