Drones will be used in the future to clear land mines and perform other dangerous tasks. Take the Mine Kafon Drone for instance. It is a demining drone that flies over dangerous areas to map, detect, and detonate landmines. It has robotic extensions and can get the job automatically.
The drone relies on a robotic metal detecting arm to detect and tag mines. A robotic gripping arm is used to place small detonators on each mine. This system lets operators clear landmines from a safe distance. More info is available here.
