mine detection

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).

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 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
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
