The Department of Homeland Security’s (DHS) Science and Technology Directorate (S&T) is funding the development of an unmanned underwater vehicle designed to resemble a tuna, called the BIOSwimmer™. Why the tuna? Because the tuna has a natural body framework ideal for unmanned underwater vehicles (UUVs), solving some of the propulsion and maneuverability problems that plague conventional UUVs.
Inspired by the real tuna, BIOSwimmer™ is a UUV designed for high maneuverability in harsh environments, with a flexible aft section and appropriately placed sets of pectoral and other fins. For those cluttered and hard-to-reach underwater places where inspection is necessary, the tuna-inspired frame is an optimal design. It can inspect the interior voids of ships such as flooded bilges and tanks, and hard to reach external areas such as steerage, propulsion and sea chests. It can also inspect and protect harbors and piers, perform area searches and carry out other security missions.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
