Christian Bettstetter and I have organized the Sixth Lakeside Research Days on Multi-UAV Systems. The event was hosted by Lakeside Labs and the University of Klagenfurt in Klagenfurt, Austria, from July 8 to 12, 2013.
We have demonstrated a multi-UAV coverage scenario with three quadrotors working together to make an overview image of a large area. The vehicles were equipped with cameras and they followed pre-computed flight paths, taking high-quality pictures at certain points. The collected images were immediately transmitted to a ground station, where the mission progress could be readily overseen and changed if necessary.
Check out our multi-UAV system in action! The video was nominated for Best Student Video in AAAI (http://www.aaaivideos.org/2013/) and was awarded second place.
