A Green Powered Sailboat

The electronics are a bit trickier, but the basic plan is to cover the deck with solar panels, and use a few sensors including GPS, IMU, and an anemometer to steer this sailboat around a lake. Building an autonomous vehicle is a hard challenge, and for the electronics, [silvio] has a trick up his sleeve: he’s using redundant electronics . All the sensors are connected via an I2C bus, so why not put two microcontrollers on that bus in a master and slave configuration? It won’t add much mass, and given the problems had by a few of the teams behind robotic sailing competitions , a bit of redundancy isn’t a bad thing to have.
