As the name suggests, a quadcopter is a flying body, which uses the medium of spinning rotors, similar to that of a full scale helicopter, to float in the air.
Quad-copters are used in multiple arenas in the modern world, such as; for surveillance, mapping, photography and many more innovative purposes.
Any quadcopter in general has the following basic parts, which are easy to understand and build.Let's take a look at some of the parts required to build such a quadcopter:
Airframe: Structure to hold the components
Battery: Powerhouse of the quadcopter
Flight control board: Brain of the quadcopter
Power distribution board: Circulation of power, to control the quadcopter
Electronic Speed Controllers: Regulate the motor speed
Brushless motor: Special type of motors for High RPM operation
Propellers: Convert spinning of motors into lift of the quad
Peripheral connectors: Miscellaneous connectors used in the quad
Transmitter and Receiver module: Helps direct the motion of the quad and hence acts as a medium of communication.
