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 ...

The odd free surface flows of a colloidal chiral fluid

Sofia Magkiriadou

In simple fluids, such as water, invariance under parity and time-reversal symmetry imposes that the rotation of constituent 'atoms' is determined by the flow and that viscous stresses damp motion. Activation of the rotational degrees of freedom of a fluid ...

Rapid Deployment of Curved Surfaces via Programmable Auxetics

Mark Pauly, Mina Konakovic Lukovic

Deployable structures are physical mechanisms that can easily transition between two or more geometric configurations; such structures enable industrial, scientific, and consumer applications at a wide variety of scales. This paper develops novel deployabl ...

The Design of A New Rotary Hexapod with A Single Active Degree of Freedom

Jamie Paik, Alexey Fomin

This study provides a novel approach for designing a rotary hexapod with a single actuator and definable motion of a platform. Hexapod is a parallel structure mechanism with six legs and six degrees of freedom (DoF) of an end-effector. It is not an underac ...

The Art of Flexure Mechanism Design

Simon Nessim Henein, Florent Cosandier, Lennart Rubbert, Murielle Richard

Flexure mechanism design is an art, and this book provides the theoretical and practical foundation for scientists and engineers to express their creativity in this field. Flexure mechanisms, also known as compliant mechanisms, rely on the elasticity of ma ...

Calculation of the General Number of Imposed Constraints of Kinematic Chains

Jamie Paik, Alexey Fomin

The study provides derivation and application of novel formula for the calculation of general imposed constraints for kinematic chains (including mechanisms and zero-degrees-of-freedom Assur groups) depending on the types of kinematic pairs and numbers of ...

Effect of static and kinematic boundary conditions on the out-of-plane response of brick masonry walls

Katrin Beyer, Filippo Lucca

The Unreinforced Wall (URM) elements that are most susceptible to out-of-plane failure are wall elements of the upper storeys where the accelerations are largest. In modern URM buildings with reinforced concrete slabs, the out-of-plane mechanism involves t ...

Modelling of the human shoulder as a parallel mechanism without constraints

Alexandre Terrier, Alain Farron, Philippe Müllhaupt, Christoph Anselm Engelhardt, David Ingram

The synthesis of shoulder kinematics, either for simulation in a model or imitation in a robot, is a challenging task because of the contact between shoulder blade and ribcage. As the shoulder moves, the shoulder blade glides over the ribcage. In kinematic ...

Hsp70 chaperones use ATP to remodel native protein oligomers and stable aggregates by entropic pulling

Paolo De Los Rios, Pierre Goloubinoff

Forceful unfolding by entropic pulling is the general mechanism by which Hsp70 and Hsp110 chaperones control the oligomeric states, structures and activities of cellular proteins. ...

Incentives for Effort in Crowdsourcing using the Peer Truth Serum

Boi Faltings, Radu Jurca, Goran Radanovic

Crowdsourcing is widely proposed as a method to solve large variety of judgement tasks, such as classifying website content, peer grading in online courses, or collecting real-world data. As the data reported by workers cannot be verified, there is a tende ...
