Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors
Advanced Intelligent Systems, EarlyView.We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

A Theoretical Investigation on Hydrostatic Bearing
Bulletin of JSME, 1962 A theoretical study was made on the following points concerning the design and analysis of the hydrostatic bearing ; (1) Optimum dimensions of the recess. (2) Correction of the load capacity and the quantity of flow for application to journal bearing. (3) Squeeze film effect in hydrostatic bearing with the recess and external restriction.

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype
Advanced Intelligent Systems, EarlyView.A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds
The Anatomical Record, EarlyView.Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.
