Have you noticed that most technological innovations reach a point where they are automated? Think of the vacuum cleaner – it was invented in the early 1900s and was a conventional household product for decades. However, in 2005 it was automated in the shape of a Roomba! The wheel has been around for centuries; we're automating it by developing self-driving cars.

Once technology reaches a threshold, we tend to eliminate the human element (so we can focus on more important tasks – or binge on Netflix while the Roomba does the cleaning!)

We conquered the skies in 1903 (thanks to the Wright brothers!) but it's time to automate the aircraft – wait, didn't we do that already? Unmanned Aerial Vehicles (or UAVs) are autonomous aircraft, essentially a plane without a pilot. UAVs have simplified our modern lives in myriad, unimaginable ways.

From agriculture and nature surveying to construction and emergency response – UAVs are the silent birds of the sky. Read on to learn more about Unmanned Aerial Vehicles (UAVs), their working, benefits, impact on our world and future trends.
