DRONES

A drone, in a technological context, is an unmanned aircraft. 

Drones are more formally known as unmanned aerial vehicles (UAV). Essentially, a drone is a flying robot. that means it's an aircraft, of any size or type, that flies by itself, without an onboard pilot or passengers. The aircraft may be remotely controlled or can fly autonomously through software-controlled flight plans in their embedded systems working in conjunction withGPS.  UAVs have most often been associated with the military but they are also used for search and rescue, surveillance, traffic monitoring, weather monitoring and firefighting, among other things. The term unmanned aircraft system (UAS) refers to the unmanned aircraft and all of its components including, but not limited to: control stations and software, remote controls (if necessary), control links, payloads, launch and recovery equipment.
