An indicial-polhamus model of aerodynamics of insect-like flapping wings in hover [PDF]
As part of the ongoing development of Flapping-Wing Micro Air Vehicle (FMAV) prototypes at RMCS Shrivenham,a model of insect-like wing aerodynamics in hover has been developed, and implemented as MATLAB code.The model is intended to give better insight ...

An origami worm‐inspired robot achieves multimodal locomotion in confined pipelines through mechatronic integration that embeds actuation, control, and communication within each origami module. Large, reversible configuration and dimensional changes enable 25 gaits synthesized by a unified framework across peristaltic, inchworm, and wheel‐rolling modes

On the Optimization Performance Study of Flapping Aerial Vehicle under Heavy Rain Condition
Flapping-Wing Aerial Vehicle generally has light-weight and small size characteristics, and its small scale is particularly suited for surveillance mission, but quite fragile to severe weather impact. Here we consider the environmental effects to measure

Numerical investigation of three-dimensional asymmetric hovering flapping flight [PDF]
Direct numerical simulations are performed to assess the aerodynamic performance of three-dimensional wings undergoing asymmetric hovering flapping flight. A large number of flapping kinematics is investigated, varying the pitch rate and the upstroke and

Fully programmable, in‐process 3D magnetization integrated with multi‐material printing enables soft magnetic systems with precise actuation and sensing. Discrete and continuous magnetization profiles drive bending, morphing, and locomotion, demonstrated through strain‐sensing elements, dragonfly‐inspired wings, octopus‐like tentacles, and a serpentine

A versatile framework integrates addressable electrothermal actuation and strain‐constraint mechanisms to construct programmable shape‐morphing soft matter systems. By combining an analytical inverse design strategy for high‐fidelity 3D surface reconstruction with deep learning‐based closed‐loop control, this approach enables zero‐energy shape locking,

Cardiac morphological and morphometric analysis of Ardea alba
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Flight of the dragons: a global review of migration in Odonata
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.
