A Dynamical System Approach to Motion and Force Generation in Contact Tasks

Aude Billard, Mahdi Khoramshahi, Walid Amanhoud

Many tasks require the robot to enter in contact with surfaces, be it to take support, to polish or to grasp an object. It is crucial that the robot controls forces both upon making contact and while in contact. While many solutions exist to control for co ...

A portable three-degrees-of-freedom force feedback origami robot for human-robot interactions

Jamie Paik, Stefano Mintchev, Marco Salerno, Alexandre Thierry Cherpillod, Simone Scaduto

Haptic interfaces can recreate the experience of touch and are necessary to improve human-robot interactions. However, at present, haptic interfaces are either electromechanical devices eliciting very limited touch sensations or devices that may provide mo ...

Optical Force Control Using Phase-Gradient Metasurfaces

Olivier Martin, Karim Achouri, Hsiang-Chu Wang

We propose to control the motion of nanoparticles using phase-gradient metasurfaces. The latter are used to generate surface waves, which put the particles into motion, when illuminated by a normally incident plane wave. We present an initial study of the ...

Analysis and Reduction of Time Response in Thermally Activated Shape Memory Alloys

Yves Perriard, Yoan René Cyrille Civet, Mario Joe Lehmann, Raphaël Johannes Charles Mottet, Sean Thomas

This paper aims to study the factors that affect the time response of Shape Memory Alloys (SMA) and establish a method to improve their activation times. In this work, different parameters such as the number, positions and orientation of the perforations o ...

Mapping the conformational free energy of aspartic acid in the gas phase and in aqueous solution

Michele Ceriotti, Kevin Rossi

The conformational free energy landscape of aspartic acid, a proteogenic amino acid involved in a wide variety of biological functions, was investigated as an example of the complexity that multiple rotatable bonds produce even in relatively simple molecul ...

Mechanism of Shiga Toxin Clustering on Membranes

Julian Charles Shillcock

The bacterial Shiga toxin interacts with its cellular receptor, the glycosphingolipid globotriaosylceramide (Gb3 or CD77), as a first step to entering target cells. Previous studies have shown that toxin molecules cluster on the plasma membrane, despite th ...

Modelling of the Cyclic Response of an Unreinforced Masonry Wall through a Force Based Beam Element

Katrin Beyer, Francesco Vanin, João Saraiva Esteves Pacheco de Almeida

The seismic assessment of existing masonry buildings is based on the prediction of their nonlinear response under lateral loading. This requires a reliable estimation of the force and displacement demand. For this purpose, modelling strategies using struct ...

Composite model for predicting the punching resistance of R-UHPFRC-RC composite slabs

Eugen Brühwiler, Maléna Bastien Masse

Adding a thin layer of Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC), with or without steel rebars, over a Reinforced Concrete (RC) slab is an efficient reinforcement method for existing structures. The thin layer of UHPFRC serves ...

2D meso-scale modeling of masonry elements using cohesive elements

Jean-François Molinari, Katrin Beyer, Nicolas Richart, Shenghan Zhang, Seyedeh Mohadeseh Taheri Mousavi

Many stone masonry structures that were constructed in the past centuries are now counted towards the cultural heritage. The low strength and brittle behavior make these heterogeneous structures very vulnerable to various natural or man-made disasters such ...
