MACKINAW CITY, Mich. (AP) -- Tens of thousands of people took part in the Labor Day walk across the Mackinac Bridge — joined by one robot.
Gov. Rick Snyder led the annual trek Monday across the 5-mile-long bridge linking Michigan's two peninsulas. His office says he walked alongside a robot constructed for the occasion by the FIRST robotics team from Macomb International Academy in the town of Armada.
FIRST is a program that encourages young people to learn about science and technology.
Several of the program's students, teachers and mentors joined Snyder and the robot, which can travel up to 10 mph and is known as "The Pi Guy."
The bridge walk began at 7 a.m., although walkers were allowed to start as late as 11 a.m. Monday.
