The undergraduate seminar „Flight Robotics“ offers the opportunity of developing flight control algorithms for quadcopters, building such a vehicle, and testing it during real flight experiments. Furthermore, the „Holzcopter“ is used as an aerial platform for flight experiments conducted as part of the research on autonomous landing. Being equipped with a Raspberry Pi 4B and a LibrePilot Revolution flight controller, it can be integrated into the Robot Operating System (ROS). For indoor flight experiments, the vehicle has several reflecting markers that enable tracking of its pose through the institute‘s motion capture system (Vicon, 10 cameras). On the one hand, this allows generating ground truth data of the vehicles motion regarding its pose, position and velocity. On the other hand, the ROS interface allows feeding of the position and velocity information into the flight controller as a simulated GPS signal. Thus, real conditions for the state estimation of the vehicle can be created for indoor flight experiments.
