The Mine Kafon Drone is designed to make clearing land mines easier, cheaper, and safer. The drone has six rotors and a trio of different attachments. The first is used to map the desired area, while the second, a metal detector, is used to detect mines, flagging them with GPS markers. After this, the drone returns to its operator and swaps its metal detector for a robot arm, which is used to place small detonators the size of tennis balls over the mines' locations. The drone then retreats to safety and the mines are detonated. The creators of the Mine Kafon Drone say their technology could potentially clear the world of these deadly devices in less than 10 years' time.Worldwide, there are thought to be some 100 million land mines, many of which are leftover from conflicts long since finished. Every year these mines kill thousands of people, the vast majority of which are innocent civilians.
