Drones are now gaining popularity. Drone is an unmanned aerial vehicle, meaning, they are not being piloted by an onboard person. Drones are basically modelled as airplanes that serve a utilitarian purpose. Drones are can be both remote controlled or controlled by a computer.
It is quite funny how drones back then were just toys or some thing that was created primarily for amusement. Then suddenly, some people customized it and made it useful which then lead to more people experimenting on drones that has then led to this project that wants to change the world with their innovative ideas. I really am very amazed with this project.
