Introduction to Drones
Drones, also known as Unmanned Aerial Vehicles (UAVs), are aircraft that operate
without a human pilot onboard. They can be controlled remotely or programmed to
fly autonomously using onboard computers and sensors. Initially developed for
military reconnaissance during World War I, drones have since evolved into
versatile tools used in various industries. Today, they are widely employed in
agriculture, logistics, surveillance, photography, and disaster management. Drones
come in different types, including fixed-wing models for long-range operations and
rotary-wing (multi-copter) designs for precision tasks. Advances in AI, GPS, and
battery technology have significantly enhanced their capabilities, making them an
integral part of modern technological innovations.
