This past month, sixty primary and middle school educators from the Bermuda Union of Teachers came to BIOS to participate in a professional development workshop focused on marine robotics.  The workshop involved PVC pipes, car batteries, foam noodles, propellers, and a race against time as participants were challenged to build their own Remotely Operated Vehicles (ROVs) for launch into the Sargasso Sea. Successful ROVs are neutrally buoyant and can be maneuvered through the water to complete tasks, mimicking the professional classes of underwater robotics used around the world to collect data for science and industry.
