With a week of robot building behind us, it’s time to put our robots, and our newly minted robot pilots to the test. Monday began with a day of tether management and pilot training. The OpenROV does not come with its own, pre-built tether management system; operators must design their own and adapt it to the unique challenges of their field environment. So we set the team off to develop their own tether management systems and the results were astounding, artistic, and clever.

With tethers securely managed, it was time for Erika’s Pilot Academy. As some teams continued to perform maintenance and troubleshooting, and some worked on their ecology projects, others were led, group by group, to the test tank, where Erika and Dominik had built a challenge course for them to fly. Without looking at the tank or robot, each student had to pilot an ROV around the tank, collect a weighted target, and bring it to the surface. Even for veteran OpenROV pilots, this exercise can be challenging. We closed out the first day of pilot training with 23 skilled pilots.

After a long week of intensive robot building, six brand new OpenROVs went into the water on Friday. Our student’s hard work paid off as their robots dove into the freshwater test tank. There are few things more rewarding than watching students, who’ve sweated over a difficult build while learning challenging new skills for 12 hours or more every day, launch their completed robots drive them around the test tank for the first time.

Of course, failure is part of our pedagogy, and two robots will require another day of troubleshooting before they can be released into the sea.

Building robots in Papua New Guinea: update from #ROV2PNG

The view from our morning commute between Nusa and Nago.

Hello from the warm, sunny island of Nago, home of the National Fisheries College field station and staging ground for Marine Ecology via Remote Observation, part of the Marine Science Short Course. My team and I arrived in Port Morseby on Friday, where we met with Jamie on her way home and and caught up with my former student, now lecturer at UPNG, Freddie Alei, who joins us for the next week of class. Another day of travel brought us to the shores of Nusa Island. We had our first chance to meet the students on Sunday, during a walk around the local beach, followed by an afternoon flying Independent Lee, one of our demonstration robots, from the Fisheries’ jetty. It was a nice warm up for an intensive week of robotics and marine ecology.

There are two major components to the #ROV2PNG portion of the Marine Science Short Course. The first, and most visible, is the construction and operation of the OpenROV, an open-source underwater robot that is incredibly adaptable and expandable. Over the last three days, students have learned how to solder, weld acrylic, test electronics, use epoxy resins, and work together to assemble the chassis, endcaps, battery tubes, motors, and brain of the robot. Excitement is mounting as we approach the moment when we can power up the ROVs for the first time.
