When it comes to drones these days, simply flying seems a bit passé. Engineers are now finding innovative ways to boost their versatility by developing bots that are just as happy in the sea as they are in the air. Most recently, researchers from John Hopkins University developed a prototype for a submersible quadcopter that can launch from a fixed position underwater, or from a vehicle like a submarine, and right into the sky.
CRACUNS — which stands for Corrosion Resistant Aerial Covert Unmanned Nautical System — boasts a low-cost, 3D-printed body that is lightweight and resistant to deep water pressure. All of its core electronics are housed in a dry pressure vessel, while the drone’s external motors have been given anti-corrosive coatings to protect them from saltwater. So far, the machine has been able to operate and has shown no signs of corrosion after remaining submerged for up to two months.
According to its creators, CRACUNS will pave the way for new capabilities not possible with existing UAV platforms, like operating in the harsh littoral (shore) environment, as well as its payload flexibility that enables a wide array of potential missions. The drone’s affordability even makes it expendable, which is perfect for high-risk scenarios.
