Analytical description of Fano resonances in plasmonic nanostructures

Olivier Martin, Benjamin Gallinet

We report on the derivation of analytical formulas for the lineshape of Fano resonances in plasmonic nanostructures as a function of their electromagnetic response. Contrary to the original work of Fano, the formalism proposed here includes losses in the m ...

Robotique collective et auto-assemblage

Michael Bonani

We present a study of collective robotics by including a mechatronics point of view. In the field it is usually claimed that collective robots are simple and relatively cheap because they are produced in large quantities. Instead in our study we show that ...

Communication-based Leashing of Real Flying Robots

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert, Severin Leven

Aerial robots are often required to remain within the communication range of a base station on the ground to exchange commands, sensor data or as a safety mechanism. For this purpose, we propose a minimal control strategy for steering flying robots using o ...

The Hand-bot, a Robot Design for Simultaneous Climbing and Manipulation

Francesco Mondada, Michael Bonani, Stéphane Magnenat, Philippe Rétornaz

We present a novel approach to mobile object manipulation for service in indoor environments. Current research in service robotics focus on single robots able to move, manipulate objects, and transport them to various locations. Our approach differs by tak ...

Control of legged locomotion using dynamical systems

Ludovic Righetti

Legged robots have gained an increased attention these past decades since they offer a promising technology for many applications in unstructured environments where the use of wheeled robots is clearly limited. Such applications include exploration and res ...

Stabilization of a 2D-SpiderCrane Mechanism Using Damping Assignment Passivity-based Control

Dominique Bonvin, Philippe Müllhaupt

Cable-operated manipulators, also termed cable robots, possess a number of unique properties which make them suitable for tasks involving high payloads, large workspaces, and interacting with dangerous materials. But the fact that cables can only pull the ...

On Achieving Periodic Joint-Motion for Redundant Robots

Denis Gillet, Philippe Müllhaupt, Yvan Michellod

The consequence of the loss of involutivity of a specific set of vector fields on the periodicity of the joint motion is examined for redundant robots. An output task, defined as a one dimensional periodic closed curve embedded in a two dimensional working ...

Tunable plasmonic nanostructures

Olivier Martin, Holger Fischer

We discuss different composite plasmonic nanostructures, which optical properties can be tuned by displacing some of their parts at the nanoscale. The actuation of these structures with MEMs will define new optical functionalities. ...

Optimisation de la conception du robot parallèle Delta cube de très haute précision

Tiavina Niaritsiry

In the high-precision industry, most operations require the use of robots able to accomplish highly accurate and repeatable motions. In order to meet the desired level of absolute accuracy, one has to limit or even suppress the effects of different sources ...
