Unmanned Aerial Vehicles (UAVs) are gaining more and more attention during the last few years due to their important contributions and cost- effective applications in several tasks such as surveillance, search and rescue missions, geographic studies, as well as military and security applications. Compared with manned aerial vehicles, due to the requirements of autonomous flight under different flight conditions without a pilot onboard, control of UAV flight is much more challenging since all operations have to be carried out by the automated flight control, navigation and guidance algorithms embedded on the onboard flight microcomputer/ microcontroller or with limited interference by a ground pilot if needed. A team of researchers at the Department of Mechanical and Industrial Engineering of Concordia University, with the financial support from NSERC (Natural Sciences and Engineering Research Council of Canada) through a Strategic Project Grant and a Discovery Project Grant and three Canadian- based industrial partners (Quanser Inc., Opal- RT Technologies Inc., and Numerica Technologies Inc.), have been working on a research and development project on fault-tolerant and cooperative control of multiple UAVs since 2007. A quadrotor helicopter UAV physical test-bed has been developed through the projects, with the help for the UAV test-bed developed by Quanser Inc. Provided with this cutting-edge research activity and outcome as well as a special financial support made by the Department of Mechanical and Industrial Engineering and the Faculty of Engineering and Computer Science at Concordia University, since September 2010, Concordia University has for the first time made use of the developed quadrotor helicopter UAV (called as Qball-X4) for two courses teaching, which includes an undergraduate/ graduate course MECH 480/ 6091 " Flight Control Systems" and a graduate course ENGR691X " Fault Diagnosis and Fault-Tolerant Control Systems" (please see a story and a video available at http:// www. concordia. ca/ now/ what-we-do/ research/ 20110321/ fourtimes-the-fun. php). Through the use of such a cutting-edge unmanned aerial vehicle, students are able to practice and test the flight control theories learnt from the courses in such a physical and practical test-bed, which help students to link theory with engineering practice and achieve an even deeper and better understanding of the theories than would be possible without such an experimental and flyable test-bed. Students are attracted and motivated to continue in their studies and work. In this paper, the overview on the objectives and contents covered in the two courses will be briefly introduced first. The system configuration and features of the developed Qball-X4 quadrotor helicopter UAV system are then introduced. Approaches, procedures and several flight testing results toward the use of the Qball-X4 UAV in the two courses for undergraduate lab development and graduate course projects development will be described. Achievement of using the Qball-X4 UAV in the courses labs and course projects are then presented. What we have learnt through the use of such a cutting-edge new UAV technology for the two courses teaching is summarized at the end of the paper.
