Mayflower turns back over glitch

The Mayflower had a few false starts before its trailblazing sea voyage to America more than 400 years ago. Now, its artificial intelligence-powered namesake is having some glitches of its own. A sleek robotic trimaran had to turn back Friday to fix a mechanical problem. Nonprofit marine research organization Promare said it made the decision to return to base “to investigate and fix a minor mechanical issue.”
