BAE Systems' Archerfish hunts down sea mines

The animal known as the archerfish has a unique claim to fame – it shoots down and then eats airborne insects by spitting a stream of water at them. Well, BAE Systems' Archerfish ROV (remote-operated vehicle) is a little different. It locates and then blows up sea mines, by shooting them with an explosive charge. Read More

Anglo-French project aims at using robots to fight underwater mines

If you hunt unexploded sea mines for a living, then you might not mind losing your job to a robot. That seems to be the reasoning of the British and French governments, as they embark on a joint venture to develop a prototype autonomous system for detecting and neutralizing sea mines and UnderWater Improvised Explosive Devices (UWIED).Read More

New algorithms improve efficiency of underwater mine-sweeping robots

In addition to human divers equipped with sonar cameras, the U.S. Navy has also trained dolphins and sea lions to search for bombs on and around vessels. All these methods are expensive and can’t always deliver the best performance in all environments. Robots would seem to be the obvious answer and underwater robots have been the focus of much research and development in recent years. Now researchers at MIT have developed new algorithms to vastly improve the navigation and feature-detecting capabilities of these robots.Read More

Land mine detection system built using off-the-shelf components

Land mines are terrifying and indiscriminate weapons, harming soldiers and civilians alike. Even long after the conflict in which they were deployed has ceased they end up killing and injuring civilians and render land impassable and unusable for decades. There are a variety of methods used to detect mines by both humanitarian and military groups, but many are dangerous, most are less than 100 percent reliable and some of the more reliable detection methods are prohibitively expensive. Physicists have now built a relatively inexpensive land mine detection system using off-the-shelf components – including some sourced from online auction sites.Read More

ONR demonstrates new counter-mine cloaking technology

Naval mine strikes are cited as the root cause of almost 4/5ths of U.S. Navy ship casualties occurring since 1950, so any device that either detects mines or cloaks the ship to avoid detonation will aid in the reduction of these alarming statistics. This new technology developed by the Office of Naval Research (ONR) consists of a high temperature superconducting (HTS) degaussing coil which acts to form a cloaking device which eliminates the magnetic signature of the ship. This interferes with undersea mines' ability to detect and detonate when a large magnetic field – like the one created by a ship – comes within close proximity.Read More
