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, where pilgrim travellers settled in 1620, the robot ship suffered "a minor mechanical issue".
ProMare, a nonprofit promoting marine research that is behind the project. Researchers pushed out a software update, signalling for the ship to reverse course.
The boat abided by its orders and headed to shore.
According to Brett Phaneuf, co-director of the Mayflower Autonomous Ship Project, the organisers quickly began planning another voyage.
"We've had a setback, but one that will put us further ahead than if we did nothing. So earlier this month, researchers sent the ship back out for a shorter trip: This time it'll focus on the waters around the United Kingdom, where crews can attend to it sooner if something unforeseen happens. "At some point, you have to go for it and take the risk or never improve", Phaneuf said.
