It has been employed to participate in the 2012 UAVForge competition. The proposed design methodology consists of hardware construction, software development, dynamic modeling and flight control, as well as mission algorithms. The test results have been presented in this paper to verify the proposed design methodology. © 2013 Springer-Verlag Berlin Heidelberg.Conference PaperNOT_IN_WOS
