Controlling quad-copters a project-based approach in the teaching of application design

In this paper we present our experiences using a project-based approach of teaching application design. We adapted a systems-engineering approach [1] for our course. Students design and implement a platform to test various input devices to control quad-copters. We use speech recognition, keyboard and mobile sensors among other items to control the copters. Students gain the theoretical background in classroom blocks and apply their knowledge in practical exercises with increasing complexity. Students present their applications at the end of the course. The input devices are tested in a flying competition. The success of lectures predominantly depends on the preparation and adequate choice of the infrastructure. Students must be able to concentrate on the application design. Therefore a set of well-documented input controller and libraries must be chosen. The libraries must hide complicated technical details, in our case details of the communication infrastructure. According to our experience, those students who are attracted by a gadget, in our case the quad-copter and different input devices, are more willing to spend time on the design and implementation of an application. Increased personal involvement and motivation lead to higher acceptance of the subject. In addition, students need to possess a good level of programming skills to profit from this type of course.
