Rigid foldability and mountain-valley crease assignments of square-twist origami pattern

Huijuan Feng

Rigid foldability allows an origami pattern to fold about crease lines without twisting or stretching component panels. It enables folding of rigid materials, facilitating the design of foldable structures. Recent study shows that rigid foldability is affe ...

Ori-Pixel, a Multi-DoFs Origami Pixel for Modular Reconfigurable Surfaces

Jamie Paik, Stefano Mintchev, Marco Salerno

Reconfigurable surfaces using robotic pixels can produce discretize 3D contours, shapes and motion patterns. In existing devices, the rendering resolution and richness of shapes and patterns are limited by the use of linear pixels that only produce single ...

Bio-Inspired Tensegrity Fish Robot

Dario Floreano, Jun Shintake, Davide Zappetti

This paper presents a method to create fish-like robots with tensegrity systems and describes a prototype modeled on the body shape of the rainbow trout with a length of 400 mm and a mass of 102 g that is driven by a waterproof servomotor. The structure of ...

A plane linkage and its tessellation for deployable structure

Chen Yan, Huijuan Feng

Deployable structures are widely used in space applications such as solar arrays and antennas. Recently, inspired by origami, more deployable structures have been developed. This paper outlined a novel design scheme for deployable structures by taking a pl ...

Identification of Mechanism Stiffness of Autoeliminating Clearance for Auxiliary Bearing

In this article, a method for identification of equivalent stiffness was proposed based on a genetic algorithm by studying the stiffness characteristics of autoeliminating clearance auxiliary bearing devices (ACABDs) in static condition. Subsequently, the ...

Design of Low-Profile Compliant Transmission Mechanisms

Jamie Paik, Zhenishbek Zhakypov, Frédéric Henri Vaskin Giraud

Robotic origami design allows creating meso-scale robotic systems and mechanisms not limited by degrees of freedom, miniaturization and assembly downsides of conventional transmission mechanisms. However, unlike the traditional rigid approaches, robotic or ...

High-speed imaging of high pressures produced by cavitation bubbles

Mohamed Farhat, Danail Obreschkow, Outi Supponen

Cavitation bubbles, when correctly tuned, may provide interesting mechanical and chemical effects to their surroundings owing to their violent collapse. Such an event may produce high-speed liquid jetting, extreme heating, as well as pressures of thousands ...

Cellular advective-diffusion drives the emergence of bacterial surface colonization patterns and heterogeneity

Alexandre Louis André Persat, Tamara Rossy

Microorganisms navigate and divide on surfaces to form multicellular structures called biofilms, the most widespread survival strategy found in the bacterial world. One common assumption is that cellular components guide the spatial architecture and arrang ...

Overlapping and essential roles for molecular and mechanical mechanisms in mycobacterial cell division

Georg Fantner, John McKinney, Adrian Pascal Nievergelt, Mélanie Thérèse Marie Hannebelle, Haig Alexander Eskandarian, Pascal Damian Odermatt

Mechanisms to control cell division are essential for cell proliferation and survival. Bacterial cell growth and division require the coordinated activity of peptidoglycan synthases and hydrolytic enzymes to maintain mechanical integrity of the cell wall. ...

Human-Human, Human-Robot and Robot-Robot Interaction While Walking: Data Analysis, Modelling and Control

Jessica Lanini

In everyday life humans perform many tasks with other partners which involve coordination, involuntary communication and mutual control adaptation, as the case of carrying objects together with another person. Humanoid robots may help with such activities ...

Improved pivot-slide model of the motion of a curling rock

Gaëtan Emmanuel Mancini

The pivot-slide model (Shegelski and Lozowski) successfully predicts the slide and curl distances of a curling rock. However, in this model, there is no dependence of the curl distance on the initial velocity, because the ratio between the pivot to sliding ...
