Vision-Based Landing of Fixed-Wing Miniature Air Vehicles

This paper outlines a method for using vision-based feedback to accurately land a MAV on a visually identifiable target of approximately known location. The method presented is robust to wind, capable of handling both stationary and moving targets, and capable of correcting for camera misalignment, state estimation biases, and parameter estimation biases. Landing results from actual flight test...

Autolanding Controller for a Fixed Wing Unmanned Air Vehicle

This paper addresses the autolanding guidance and control problem for unmanned autonomous vehicles (UAV) based on the information provided by the onboard Navigation System. The proposed solution relies on a path-following and velocity profile tracking controller synthesized using an accurate aircraft dynamic model, referred to as SymAirDyn, which was designed with the objective of exploiting th...

A Fixed-Wing Micro Air Vehicle with Hovering Capability

The present project is the sequel of a transatlantic collaborative research project started in 2007 with the University of Arizona and the group of Dr. Sergey Shkarayev. The previous research grant was devoted to the comparative study of tilt-rotor and tilt-body configurations for Micro Aerial Vehicles (MAV). The purpose of the present study is to investigate the potential benefit of combining ...

Wireless cell Fixed Network Fixed Host Fixed Host Fixed Host

Mobile computing is a new emerging computing paradigm posing many challenging data management problems. We identify these new challenges and investigate their technical signi cance. New research problems include management of location dependent data, frequent disconnections, structuring distributed algorithms for mobile hosts, wireless data broadcasting, and energy e cient data access.
