VDM-based navigation for Delta-wing UAVs: Models, calibration, implementation

Autonomous navigation of small UAVs is typically based on the integration of inertial navigation systems (INS) together with global navigation satellite systems (GNSS). However, GNSS signals can face various forms of interference affecting their continuous ...

How to Swoop and Grasp Like a Bird With a Passive Claw for a High-Speed Grasping

Dario Floreano, William John Stewart, Enrico Ajanic, Matthias Müller

There is a growing interest in unmanned aerial vehicles (UAVs) grasping, perching, and interacting with their surroundings by means of claws, arms, hooks, and other appendages. While multirotor vehicles can slowly lower onto a target object and grasp it, w ...

Mapping with MAV: Experimental Study on the Contribution of Absolute and Relative Aerial Position Control

Jan Skaloud, Martin Rehak

This study highlights the benefit of precise aerial position control in the context of mapping using frame-based imagery taken by small UAVs. We execute several flights with a custom Micro Aerial Vehicle (MAV) octocopter over a small calibration field equi ...

Energy Management for Indoor Hovering Robots

Dario Floreano, Jean-Christophe Zufferey, James Roberts

Flying has an advantage when compared to ground based locomotion, as it simplifies the task of overcoming obstacles and allows for rapid coverage of an area while also providing a birds-eye-view of the environment. One of the key challenges that has preven ...

A 1.5g SMA-actuated Microglider looking for the Light

Dario Floreano, André Guignard, Mirko Kovac, Jean-Christophe Zufferey, Jean-Daniel Nicoud

Unpowered flight can be used in microrobotics to overcome ground obstacles and to increase the traveling distance per energy unit. In order to explore the potential of goal-directed gliding in the domain of miniature robotics, we developed a 22cm microglid ...

Cavitation in Kármán Vortex Shedding from 2D Hydrofoil: Wall Roughness effects

François Avellan, Mohamed Farhat, Philippe Ausoni

The present study deals with the shedding process of the Kármán vortices in the wake of a NACA0009 hydrofoil at high Reynolds number. This research addresses the effects of the foil leading edge roughness on the wake dynamic with a special focus on the vor ...

Bio-inspired vision-based flying robots

Jean-Christophe Zufferey

There are not yet autonomous flying robots capable of manoeuvring in small cluttered environments as insects do. Encouraged by this observation, this thesis presents the development of ultra-light flying robots and control systems going one step toward ful ...
