Quadcopter Analysis
HARDWARE
3.1 INTRODUCTION
Quadcopter is a flying vehicle with six degrees of freedom which uses four rotors to push air downwards and to create a thrust force for keeping the quadcopter on the air. The pilot or flight control unit will control the orientation and tile of the multicopter by reading the data from the sensors. Gyro, accelerometer, magnetometer or GPS can be used to sense the tile, orientation and position of the vehicle. It can be used in many applications merely by changing the sensors on the quadcopter. Quadcopter of different sizes can be built depending on the application.
This subsystem is the main part of our project. This subsystem involves the dual function. First function is to monitor different data on the touch screen …show more content…
It processes all the information based on the inputs given to it through sensors. PID algorithm is embedded into the controller and thus the stability of the quadcopter will be achieved. PID algorithm works based on the inputs from accelerometer and gyroscope. The digital output from the controller depending upon the PID algorithm will be used to control the motors through electronic speed controllers. We will be using Arduino MEGA board in our quadcopter. Which has an ATmega 2560 controller, 56 digital I/O pins ( 16 can be used for PWM outputs),16 analog input pins.
3.2.2.2: Electronic Speed Controllers (ESC): An electronic speed control or ESC is an electronic circuit with the purpose to vary an electric motor's speed, its direction and possibly also to act as a dynamic brake. ESCs are often used on electrically powered radio controlled models, with the variety most often used for brushless motors essentially providing an electronically generated three-phase electric power low voltage source of energy for the motor. Some of the features of ESC’s include brake, soft start, battery eliminator circuit, automatic cut-off and optical …show more content…
The Accelerometer and gyroscope are used to provide information about the orientation of the quadcopter and the out of these are used as an input to the PID algorithm. The information sent from the sensor interface of the quadcopter can be used for gathering information about the environmental conditions, surveillance etc. Different sensors which can be used are temperature sensor, pressure sensor, ultrasonic sensor, humidity sensor, fire sensor, PIR sensor etc. The use of sensors depends on the application for which the quadcopter is being used.
Camera is fixed to the quadcopter in order to capture the real time images and it can be used to transmit the live video feed from the quadcopter to the ground station i.e. to the hand held device. GPS module can also be used on the quadcopter to provide the exact location of the quadcopter to the user and thus help him to locate the quadcopter in case of an emergency or to constantly monitor the path of the
