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. Quadcopter is a multi-rotor air vehicle which has marked its interests for the benefit of both civil and military domains. It's amazing manoeuvrability and the ease to fly in constricted locations has achieved itself a remarkable position in the aviation sector.

DESIGNING

2. 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.

3. COMPONENTS REQUIRED
 Frame
 Brushless Motor
 Electronic Speed Controller (ESC)
 Radio Transmitter and Receiver (Radio Controller)
 Lithium Polymer Battery (lipo-battery)
 Lipo Battery Charger
 Lipo Battery Alarm
 Flight Controller
 Propellers
 Power Distribution Board

4. Frame
 Size can be 450mm, 350mm, 600mm
 Two Mode X and +
 With or Without Landing Gear

5. Brushless Motor
 These are 3 phase DC Brushless Moter
 Can Have 1000KV, 930KV, 1200KV, 1400KV, 22000KV
 Operating Voltage Range 7 to 14 Volt of 30, 40, 10, 20 Ampere Rate

6. Electronic Speed Controller (ESC)
 Ampere Rating 30A, 40A, 10A, 20A
 Operating Voltage Range 7 to 14 Volt
 Has its own micro-controller
 Controlled by Pulse Width Modulation(PWM) Signal (1000 to 2000us)

7. Flight Controller Board
 Known as Brain of the Quadcopter and has it own micro-controller
 It has gyroscopes and accelerometers sensor for flight stability
 Has special PID Algorithm for flight stability
 Further modules can be added, such as GPS for advancement

8. Lipo Battery
 High Discharging rate, light weight but highly explosive and costly
 3s(3 cell) 11.1Volt of 25c, 35c, 45c
 Total charge = 2200mah*25c/1000

12. 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!

13. 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.

14. 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.

15. 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.
