Navy reveals mini drone that can scour a beach for mines

US Navy researchers have developed a drone system that can detect mines and other hazards. The portable, one-pound remote-controlled quadcopter drone can detect buried or underwater mines during amphibious beach landings conducted by US Marines. It was designed to help explosives disposal teams quickly find mines and dangerous metal structures within coastal areas and shallow water zones. The one-pound quadcopter was unveiled at Marine Corps Base Camp Pendleton in San Diego County, California. It has a magnetometer sensor system - which measures magnetism - to detect mines and provide real-time search data to a handheld Android device.
