QUADCOPTERDESIGNING

INTRODUCTION Quadcopter (from Quad “four” and Copter “helicopter”) is an aerial

robot combining a simple propeller mechanism with powerful electronics for limitless real-world applications.

It is an embedded system comprising of microcontrollers, sensors, flight gear and other integrated components.

A quadcopter, also called a quadrotor helicopter or drone, is a multirotor helicopter that is lifted and propelled by four rotors.

Drones have already been used in various industries for years. So, let’s look at some

cool things drones can already do and what amazing things they could bring us in

the future!

Deliver Online Shopping Orders and Foods Amazon has recently announced a service called Amazon Prime Air, a

service which will deliver smaller Amazon orders right to your door the same day you make the purchase. And all of this will be made possible with flying drones.

Also, Dominos Pizza has recently tested delivering your favourite pizza via a remote-controlled drone, which can carry two large pizzas and deliver them in 10 minutes within a 4 mile radius. Pretty impressive.

Drones can not only deliver books and other small online purchases you made, but also fly your lunch right to you.

Transport People Now let’s think big for a moment. If small drones can carry small

things, than bigger ones can carry bigger ones, including people. The German company e-volo has developed a technology that will

allow people to be transported from one point to another in a drone. At the moment, the 16-propeller Volocopter can fly for up to 20 minutes, but with future developments in battery technology, the Volocopter could fly for up to one hour or even more.

CONCLUSION In the past few years, flying drones have become more popular and

way more affordable. This led to a lot of new ways people use drones in both their personal lives as a hobby or even for business. In case you are thinking of buying a drone, go ahead and check them out on Amazon, where you can find some for as low as Rs. 1000.
