…Originally, OceanOne was not an archaeological robot—it was conceptualized by King Abdullah University of Science and Technology (KAUST) in Saudi Arabia as a way of monitoring deep coral reefs in the Red Sea. Christian Voolstra, assistant professor of marine science at KAUST’s Red Sea Research Center, explained where the idea came from in an interview last year:
Currently people use a so-called ROV (remote operated vehicle), which is a little submarine with two robotic arms and very limited dexterity. Using the ROV to examine delicate coral colonies proved to be troublesome. Prof. Khaled Salama (who is a professor in KAUST’s electrical engineering division) knew people at Stanford University who might be able to aid us in creating a new robotic interface system. We got in touch with the Stanford team and told them that we were not happy with the engineering solutions that are currently available. They said, “Ok, we know how to build robots … why not build an underwater robot?”
OceanOne is different from, and arguably better than, traditional underwater ROVs for a bunch of reasons. It’s smaller, approximately the size of a human diver (about 5 feet in length), which helps keep it nimble. Rather than waterproofing the electronics to keep air in, they’re immersed in oil instead, which doesn’t compress, giving the robot a maximum depth of 2000 meters (!). OceanOne is designed to maneuver with precision in tight spaces using eight thrusters, and can autonomously keep itself stable in currents or surge. With current underwater vehicles, “you spent the majority of time keeping the robot stable,” Dr. Voolstra told IEEE Spectrum, “rather than focusing on the research task.”
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
