'Sailbot' 2013

Robotics students put skills to watery tests

Sailboats measuring at about three or four feet high graced the waterfront near Pavilion Beach Monday, gliding across the water under the remote control direction of students and engineers from as far as Wales and as close as our own Gloucester High School.

The International Robotic Sailing competition — known as Sailbot — is the city’s first time hosting together the seventh annual competition that drew in 13 teams and 16 boats to try their hand at navigation and racing this year. Iain Kerr of the Ocean Alliance, who helped bring the program to Gloucester and is facilitating it, said he has enjoyed watching the students experiment and run their boats.

“I think it’s going great,” Kerr said. “I think we’ve had lots of technical problems, but actually what this is all about.

“It’s so easy to do this stuff in the lab, but that’s what this is all about,” Kerr said. “There’s two things that I like that I’m seeing a lot of — the different teams are helping each other and the real pleasure of them seeing a real world application.”

Gloucester High School students programmed two sailboats as part of a class led by coach Kurt Lichtenwald. The class presented an opportunity to combine interests in sailing and in robotics. That was an opportunity that Gloucester High student and soon-to-be senior Kaleb Church jumped at.

“I’ve always been into sailing and I figured I might as well combine my two interests, do something fun, and add my knowledge to the group,” Church said.

Gloucester High School’s boats sat on tables across boats from Olin College and Tufts Monday afternoon. The teams tinkered with the engines mid-afternoon, switching from autonomous engines that had been programmed to steer the boats themselves around an obstacle course Monday morning to a control system that the programmers steered using an iPad.
