Flying Bots: Global Hawk and Pointer
The military uses several different flying robots, mainly for reconnaissance. Instead of UGVs, these are known as UAVs (unmanned aerial vehicles), and they are sometimes referred to as drones. UAVs look like model aircraft, and they range in size from small planes that can be held by a person and launched with a good throw, like the FQM-151 Pointer, to full-size airplanes that operate by remote control, like the RQ-4A Global Hawk.
