Farming is one of the new frontiers, as food production has become more automated – everything from GPS-guided tractors to automated milking machines - and drones are started to be incorporated into what's known as precision agriculture.
Robots are being used to survey crops and help farmers manage the water and chemicals they use in vast fields. Chris Anderson, the former editor-in-chief of Wired magazine, recently switched careers to move into drone manufacturing. He co-founded 3D Robotics, which is building drones in Mexico and the US which may one day keep a beady electronic eye on the food being grown for our tables.
