DESIGN AND DEVELOPMENT OF QUADCOPTER FROM SCRATCH

Quad copter can achieve vertical flight in a stable manner and can be used to monitor or collect data in a region such as loading mass. The project goal was to design the semi-autonomous Quad copter to minimize the cost and develop it from the scratch. This means going through the process of researching previous models, performing calculations, purchasing individual parts, testing those parts, designing the final product .In this we initially decided how big we want the quad copter and then we made necessary calculation based on the previous research work to calculate the size of propeller ,capacity of motor .In this project a simple approach is being used to design and develop quad copter using a flight controller (KK flight controller board). The input for the controller board is through a receiver mounted on the quad copter which takes input from the user using a transmitter. In the project we have used 2.4 GHz transmitter due to the fact that it is a free frequency and data loss at this frequency is minimum. Flight controller board in response to it controls the speed of the brushless dc motor using an electronic speed controller.
