Self-sensing, tunable monolayer MoS2 nanoelectromechanical resonators

Andras Kis, Dumitru Dumcenco, Guilherme Migliato Marega, Sajedeh Manzeli

Excellent mechanical properties and the presence of piezoresistivity make single layers of transition metal dichalcogenides (TMDCs) viable candidates for integration in nanoelectromechanical systems (NEMS). We report on the realization of electromechanical ...

Leap-frog transport of magnetically driven anisotropic colloidal rotors

Ignacio Pagonabarraga Mora

In this article, we combine experiments and theory to investigate the transport properties of anisotropic hematite colloidal rotors that dynam ically assemble into translating clusters upon application of a rotating magnetic field. The applied field exerts ...

A comparative study of mode I delamination behavior of unidirectional glass fiber-reinforced polymers with epoxy and polyurethane matrices using two methods

John Botsis, Georgios Pappas

The mode I delamination behavior of a unidirectional glass-fiber reinforced polymer with a prototype elasto-plastic polyurethane matrix (GF/PU) was investigated and compared with that of glass/epoxy (GF/EP) using double cantilever beam specimens. Fracture ...

Haptic feedback perception and learning with cable-driven guidance in exosuit teleoperation of a simulated drone

Dario Floreano, Auke Ijspeert, Vivek Ramachandran, Amy Roning Wu, Carine Rognon

Robotics teleoperation enables human operators to control the movements of distally located robots. The development of new wearable interfaces as alternatives to hand-held controllers has created new modalities of control, which are more intuitive to use. ...

Towards Understanding of Human Kinematic Coordination Patterns in Bimanual Fine Manipulation Tasks

Aude Billard, Kunpeng Yao, Anaïs Betsabeh Haget

Skills that require the collaboration of both arms are common in humans’ everyday activities, and the coordination of upper limbs is key to human bimanual dexterity. The Skill Acquisition in Humans and Robots (ERC) project aims at obtaining a better unders ...

Multithermal-Multibaric Molecular Simulations from a Variational Principle

Pablo Miguel Piaggi, Michele Parrinello

We present a method for performing multithermal-multibaric molecular dynamics simulations that sample entire regions of the temperature-pressure (TP) phase diagram. The method uses a variational principle [Valsson and Parrinello, Phys. Rev. Lett. 113, 0906 ...

Gel-Based Soft Interfaces for Fastener Manipulation in Robotic Agile Assembly

Josephine Anna Eleanor Hughes, Kieran Daniel Gilday

Robotic manufacturing is increasingly moving towards one-off assembly tasks. Agile manufacturing systems must be able to adapt to changing parts and designs. The addition of a soft interface, between a picking tool and a part, can improve the performance a ...

Frequency-Aware Model Predictive Control

Marco Hutter, Farbod Farshidian

Transferring solutions found by trajectory optimization to robotic hardware remains a challenging task. When the optimization fully exploits the provided model to perform dynamic tasks, the presence of unmodeled dynamics renders the motion infeasible on th ...

A novel microfabrication platform for hybrid multilayer MEMS

Nahid Hosseini

In Atomic force microscopy (AFM), the tip-sample interaction force can be measured through two primary detection techniques: optical beam detection (OBD) and electrical (self-sensing) readout. Compared to the optical method, the convenience of the self-sen ...

AMBER and CHARMM Force Fields Inconsistently Portray the Microscopic Details of Phosphorylation

Veronika Juraskova

Phosphorylation of serine, threonine, and tyrosine is one of the most frequently occurring and crucial post-translational modifications of proteins often associated with important structural and functional changes. We investigated the direct effect of phos ...
