WHAT IS A DRONE?
Drones are more formally known as unmanned aerial vehicles (UAV) or remotely piloted aerial systems (RPAS). Basically, a drone is a flying robot. The aircraft may be remotely controlled or can fly autonomously through software-controlled flight plans in their embedded systems working in conjunction with GPS. UAVs have most often been associated with the military, but they are also used for search and rescue, surveillance, traffic monitoring, weather monitoring, condition monitoring of structures and fire-fighting.
For a drone to be of practical use, it needs to be equipped with a camera. Increasingly, ultra high-definition (4K) cameras are built into these devices and enable high-quality images and video to be captured or streamed back to the operator or other location for analysis.
