Pseudomonas aeruginosa orchestrates twitching motility by sequential control of type IV pili movements

Alexandre Louis André Persat, Lorenzo Anton-Louis Talà

Prokaryotes have the ability to walk on surfaces using type IV pili (TFP), a motility mechanism known as twitching(1,2). Molecular motors drive TFP extension and retraction, but whether and how these movements are coordinated is unknown(3). Here, we reveal ...

Adaptive locomotion of artificial microswimmers

Mahmut Selman Sakar, Fazil Emre Uslu

Bacteria can exploit mechanics to display remarkable plasticity in response to locally changing physical and chemical conditions. Compliant structures play a notable role in their taxis behavior, specifically for navigation inside complex and structured en ...

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

Dario Floreano, Auke Ijspeert, Amy Roning Wu, Vivek Ramachandran, 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. ...

FlyJacket: An Upper Body Soft Exoskeleton for Immersive Drone Control

David Atienza Alonso, Dario Floreano, Stefano Mintchev, Fabio Isidoro Tiberio Dell'Agnola, Carine Rognon, Alexandre Thierry Cherpillod

Most human–drone interfaces, such as joysticks and remote controllers, require attention and developed skills during teleoperation. Wearable interfaces could enable a more natural and intuitive control of drones, which would make this technology accessible ...

Soft Biomimetic Fish Robot Made of Dielectric Elastomer Actuators

Dario Floreano, Herbert Shea, Jun Shintake, Vito Cacucciolo

This article presents the design, fabrication, and characterization of a soft biomimetic robotic fish based on dielectric elastomer actuators (DEAs) that swims by body and/or caudal fin (BCF) propulsion. BCF is a promising locomotion mechanism that potenti ...

Development of Bio-inspired Underwater Robot with Adaptive Morphology Capable of Multiple Swimming Modes

Dario Floreano, Stefano Mintchev, Jun Shintake, Thibaut André Pierre Paschal

Bio-inspired underwater robots have several benefits compared to traditional underwater vehicles such as agility, efficiency, and an environmentally friendly body. However, the bio-inspired underwater robots developed so far have a single swimming mode, wh ...

Instrumented shoes for daily activity monitoring in healthy and at risk populations

Christopher Moufawad El Achkar

Daily activity reflects the health status of an individual. Ageing and disease drastically affect all dimensions of mobility, from the number of active bouts to their duration and intensity. Performing less activity leads to muscle deterioration and furthe ...

Soft micromachines with programmable motility and morphology

Mahmut Selman Sakar

Nature provides a wide range of inspiration for building mobile micromachines that can navigate through confined heterogenous environments and perform minimally invasive environmental and biomedical operations. For example, microstructures fabricated in th ...

Instrumented shoes for activity classification in the elderly

Kamiar Aminian, Anisoara Ionescu, Christopher Moufawad El Achkar

Quantifying daily physical activity in older adults can provide relevant monitoring and diagnostic information about risk of fall and frailty. In this study, we introduce instrumented shoes capable of recording movement and foot loading data unobtrusively ...

Spatio-temporal gait analysis in children with cerebral palsy using foot-worn inertial sensors

Kamiar Aminian, Benoît Mariani

A child's natural gait pattern may be affected by the gait laboratory environment. Wearable devices using body-worn sensors have been developed for gait analysis. The purpose of this study was to validate and explore the use of foot-worn inertial sensors f ...
