After IBM failed to sail an autonomous boat across the Atlantic, it’s trying again

Propelled by IBM’s AI software, the autonomous ship set out in June for a month-long excursion through rough waters with no humans aboard. However, three days into what was supposed to be a monumental journey from Plymouth, England, to Plymouth, Mass., where pilgrim travelers settled in 1620, the robot ship suffered “a minor mechanical issue” according to ProMare, a nonprofit promoting marine research that is behind the project.
