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.
