The world's seas are in an ocean of trouble: climate change, vanishing fish, coral bleaching. Just keeping tabs on an airless environment that covers three-quarters of the earth's surface is a bit like exploring a distant planet. Which means it's best to send in the robots. Unfortunately, today most oceangoing bots are big, dumb, and expensive. But not the Starbug. Under development in Australia, the 4-foot-long robot operates autonomously and is highly maneuverable, thanks to its innovative thruster technology and robotic vision.
