NASA releases details of Titan submarine concept

By - February 10, 2015 4 Pictures
Now that NASA has got the hang of planetary rovers, the space agency is looking at sending submarines into space around the year 2040. At the recent 2015 NASA Institute for Advanced Concepts (NIAC) Symposium in Cocoa Beach, Florida, NASA scientists and engineers presented a study of the Titan Submarine Phase I Conceptual Design, which outlines a possible mission to Saturn's largest moon, Titan, where the unmanned submersible would explore the seas of liquid hydrocarbons at the Titanian poles.

Underwater vehicle uses a balloon to dart like an octopus

By - February 5, 2015
When you inflate a balloon and then release it without tying the valve shut, it certainly shoots away quickly. Octopi utilize the same basic principle, although they suck in and then rapidly expel water. An international team of scientists have now replicated that system in a soft-bodied miniature underwater vehicle, which could pave the way for very quickly-accelerating full-size submersibles.

Robot sub beats nets for discovering what lurks at the bottom of the sea

By - January 13, 2015 2 Pictures
Curious about what's living on the deep sea floor? Well, the Autosub6000 AUV (autonomous underwater vehicle) is helping us find out. Led by Dr. Kirsty Morris, a team at the UK's National Oceanography Centre (NOC) has equipped one of the unmanned submarines with a high-resolution photographic system. As a result, it's claimed to be far more effective at identifying deep-sea life than the usual approach of scientific trawling. Read More

Sea turtle robot charges its own batteries

By - December 30, 2014 2 Pictures
They may be slow on land, but when they're in the water, sea turtles are fast and maneuverable – qualities that are also desirable in underwater robots. Additionally, the robotic equivalent of a turtle's streamlined shell could be stuffed full of electronic components and batteries. It shouldn't come as a surprise, therefore, that both ETH Zurich and the ARROWS project have recently created their own turtle-bots. Now, the National University of Singapore has announced its own entry in the field, that can self-charge its batteries while at sea. Read More

US Navy introducing system to help commanders plot the best course

By - December 21, 2014
One thing that is guaranteed to put a naval ship commander in front of a court martial is running aground. Unfortunately, despite all the advances in satellite technology and other aids, navigation is still as much an art as a science – and a very time-consuming one at that, with it taking days and sometimes weeks to chart out a mission. To free up captains and reduce their chances of having to answer awkward questions, the US Navy is introducing a new automated navigation planning system into its surface fleet that speeds up course planning and reduces the chance of human error.

US Navy tests GhostSwimmer "roboshark"

By - December 18, 2014 3 Pictures
Should you be swimming in the ocean sometime soon and spot a shark-like dorsal fin cutting through the water towards you, just relax – it might simply be a military robot, that's made to look like a shark. A US Navy team has recently been testing just such a device at its Joint Expeditionary Base East, in Virginia Beach, Virginia. Known as the GhostSwimmer, the robot was developed by Boston Engineering as part of the Navy's Silent NEMO project, which is aimed at creating nature-inspired unmanned underwater vehicles (UUVs).

Autonomous sub explores the depths on its own

By - December 12, 2014
Although it's tempting to refer to vehicle in the photo above as an ROV – a Remote-Operated Vehicle – the whole idea behind it is that it doesn't require an operator. Created by a team at Japan's Okayama University, the MOS/AUV (Move on Sensing/Autonomous Underwater Vehicle) is designed to find its own way along the bottom of the sea or a lake, performing various tasks as it does so.

BAE Systems and the Open University design atmospheric monitoring system for UK subs

By - December 1, 2014 2 Pictures
BAE Systems and the Open University (OU) have teamed up to design a cutting edge atmospheric monitoring system for the UK's next generation of military submarines. The system boasts a number of advancements over its predecessor, with many of the updates coming from techniques mastered by OU scientists while developing equipment for the Rosetta comet chasing mission.
