Mine-disposal robots. Computer artwork of flying robots, a possible future technology, being used to find and detonate mines in a minefield. Mines (also called landmines) are explosive weapons used in war to make an area of land too dangerous for enemy troops and vehicles to use. Landmines are rarely removed after the war, and they cause death and limb loss among civilians long after the war is over. These robots are using lasers to detect and detonate the landmines.
