Aim of the Project:–
To build a remote controlled quadcopter using KK flight control board as the controlling unit.
• Quadcopter frame
A quadcopter is a four rotor unmanned aerial drone that operates with the same principle as of a helicopter with slight differences lying within both. It is used for several purposes in the military as well as social fields operating over a wide range of applications. It has become a craze for building a quadcopter among people as it gives a wide variety of benefits as compared to the traditional helicopter such as stability and control. Till date quadcopter has only been used as a drone that is controlled from a distant place.
Since the quadcopter is an unmanned aerial drone transmission of signals takes place wirelessly via radio frequency transmission system (RFTS). This is achieved by means of a 6 channel radio control transmitter and receiver.
The four BLDC motors are mounted on the ends of the quad frame each connected to the flight control board via ESC. The 4 motors are connected in parallel to the supply battery. The ESCs are connected to their respective 4 pins M1, M2, M3 and M4 on the KK board. The receiver is then attached to the KK board. Four channels are used in the receiver for the four different movements and are connected to their respective pins namely the throttle, elevator, aileron and rudder pins. Only one of the pin pair is made in connection to the Vcc and Gnd pins and the remaining three are connected via signal pins. The KK board is an inbuilt microprocessor that gives out the desired output to the motors by receiving the signals for the different movements via the receiver.
Like this, it has got many more applications. It is a very essential and productive device for the modern generation of technology.
