QUADROCOPTER

Abstract

A Quadrocopter, also called a quadrotor helicopter or quadcopter, is an aircraft that is lifted and propelled by four rotors. The main objective of this project is to build a mechanical design of four–rotor helicopter stabilized by digital controls that use feedback. Quadrocopter is a system that is unstable and nonlinear, moreover it is controlled by a system on chip so this project provides an innovative look into the field of controls and operating system. An electronic control system along with electronic sensors will be used for its stabilization. The design will be implemented in order to achieve successful controlled autonomous hover and to provide full threeaxis manoeuvrability. The Quadrocopter with the help of a digital camera attached on board can provide a bird’s eye view of what it would see in-flight. The project utilizes a BeagleBoard (on board computer system) along with an IMU (inertial measurement unit) to control four brushless motors. Application and uses of Quadrocopter include reconnaissance, surveillance rescue efforts and target acquisition.
