To see how to set up the development environments for this drone project, see https://kbumsik.atlassian.net/wiki/display/FCFD/Using+IDE
hardware: schematics and bill of materials of the drone project.settings: templete used in this project and default IDE settings.source: the main libraryproject_components: project for each components of this project.project_main: main project of this drone.Theory references: PDF files we referenced.tracking_with_MPU9150: tracking the position of the sensor. If this works, we will have a fix coordinate to represent all relevent quantities, like forces, accelerations, angles and so on. our naming and coding conventions is following FreeRTOS's coding conventions: http://www.freertos.org/FreeRTOS-Coding-Standard-and-Style-Guide.html
