Back to the Future: Blended Wing Gliders Could Redefine Undersea Warfare

,along with its cousins the Kongsberg SeaGlider, originally developed by the University of Washington, and Spray Glider, jointly developed by Woods Hole and Scripps Institute of Oceanography, have been at the forefront of the marine robotics revolution. Gliders are unique among autonomous underwater vehicles (AUVs). Rather than use thrusters or propellers for propulsion, they rely on changes in buoyancy, in combination with wings and stabilizers, to "fly" through the water column in an up-and-down, sawtooth fashion, periodically surfacing to communicate with human operators ("pilots"

new client.” Arnoud Kuis, Managing Director of Offshore Wind at Van Oord said: “The vessel will be deployed at various Van Oord projects, as a trenching support vessel, and will be the main platform for the Van Oord trencher Dig-It.”The Dig-It is Tracked Remotely Operated Vehicle (TROV), with its tracks as its primary method of propulsion. It is a remote-controlled trench jetting and cutting system as well as a cable burial system. Its first project was the cable burial work at the Borkum Riffgrund 2 offshore wind farm in Germany in 2018.Dig-it on deck - Credit: Van

Moon landers held my attention in the 1960’s as a teenager.  Unmanned robotic vehicles like Surveyor, descend out of a dark sky onto an alien world, and took the first look around.The deep and dark ocean seemed as distant and alien.  SEALAB II, bathyscaphe Trieste, and the Scripps Institution of Oceanography in my hometown of San Diego had immense gravitational pull on my curiosity.Ocean Landers, unmanned robotic vehicles, like Scripps Professor John Issacs’ Monster Camera, descend out of a dark sea onto an alien world, and took the first look around.  Our first glimpse of

;s work will help NASA explore oceans on other worlds in our solar system.Central to the two missions is the deployment of underwater technology, low power miniaturized sensors and terrain-based navigation. For WHOI’s part, it’s developing a low-cost, full ocean depth autonomous underwater vehicle platform (AUV), Orpheus, and a miniaturized chemical sensing, while JPL is giving Orpheus the ability to navigate, using image-based terrain relative navigation (TRN) – technology developed for use by the Mars rover and Ingenuity, its robot helicopter colleague. It may sound like science fiction


Hydromea's Wireless ROV Tested at TotalEnergies’ FPSO Ballast Water Tank
