Design and implementation of coaxial quadrotor for an autonomous outdoor flight

This paper discuss about a design and implementation of coaxial quadrotor for autonomous outdoor flight. On every axis of the quadrotor installed two motors and propellers coaxially, thus it has eight in total. This configuration designed to fulfill the requirement for carrying some payload system for ground´s still and clip capturing during the flight. The modeling and control design approach developed based on the quadrotor helicopter. And onboard control system powered by a classical control, then a modern control will be implemented in advance. Global positioning system module used as navigation expected to be optimized in the future by a simultaneous localization and mapping. The experimental setup and flight test has been done successfully.
