Artificial Intelligence. GPS drones. Robots. These three phrases often bring to mind images and scenes from Science Ficition movies or TV shows.
Interestingly, these are all Science Fact now, and have been for some time. GPS drones use satellites and computer programming to fly/drive over specific areas. These drones are un-manned and are often fitted with cameras to monitor the areas being surveyed. The US military used the drones to fire missiles in 'drone strikes' during the Afghanistan war.
Drone production has cost governments millions of dollars annually for decades. In recent years, hobbyists began building them as recreational projects. Manufacturing giants in Asian countries saw an opportunity and have begun mass producing the components at very reasonable prices.
Youtube and Vimeo are full of videos from amatuers who have designed and built quadcopters mounted with high definition cameras. These flying machines are sometimes manned using a remote control with joystick, but are often drone-like and are controlled entirely by a computer program.
