Multimodal Locomotion of Soft Robots

Advanced Intelligent Systems, Volume 8, Issue 2, February 2026.
This review comprehensively surveys recent advances in multimodal locomotion within soft robotics. Typical locomotion modes are summarized and categorized. Furthermore, the underlying mechanisms enabling multimodal locomotion are discussed and classified into three primary categories: active control‐based, reconfiguration‐based, and environment ...

Experimental Investigation of a Fully‐Passive Bidirectional Hydrokinetic Turbine With Elliptical Foils in Tandem for Tidal Stream Power Generation

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
A dual bidirectional flapping‐foil hydrokinetic turbine (DBFHT) capable of fully passive bidirectional operation was proposed and experimentally evaluated in a large circulating water channel at the Korea Institute of Ocean Science and Technology (KIOST).

Untangling sedimentation processes in a deep fjord lake in Labrador: A high‐resolution archive of past environment dynamics at Grand Lake

The Depositional Record, Volume 11, Issue 5, Page 1259-1284, November 2025.
Sedimentological and geochemical characteristics are used to reconstruct sedimentation dynamics and erosional processes. Several rapidly deposited layers are characterised over changing depositional environments during the Late Holocene, from a phase when the lake was connected to the sea to a more stable state conducive to varve formation.

Numerical Study on Hydrodynamic Performance of a Pitching Hydrofoil with Chordwise and Spanwise Deformation

Journal of Marine Science and Engineering
The hydrofoil plays a crucial role in tidal current energy (TCE) devices, such as horizontal-axis turbines (HATs), vertical-axis turbines (VATs), and oscillating hydrofoils.

Flow Memory Effect on Open‐Frame Remotely Operated Vehicle Motion

Journal of Field Robotics, Volume 42, Issue 6, Page 2611-2638, September 2025.
ABSTRACT The flow memory effect is a kind of viscous force caused by acceleration between continuous phases and underwater vehicles and the development of the boundary layer near the interfacial surface. This paper establishes a 6‐degrees‐of‐freedom unsteady equation of motion describing the flow memory effect on viscous hydrodynamic loads.

Research on swimming hydrodynamics based on a three‐dimensional high‐precision fish model

River, Volume 4, Issue 3, Page 341-350, August 2025.
Abstract Fish swimming hydrodynamics serves as a critical foundation for aquatic ecological conservation, with recent research extending from 2D to 3D perspectives. This study employs 3D high‐fidelity modeling with dynamic mesh technology to investigate how cylindrical obstacles at varying positions affect Carassius auratus locomotion. Analysis of nine

Effect of wake interaction on the response of two tandem oscillating hydrofoils [PDF]

Energy Science & Engineering, 2019
AbstractIn this study, using a hydraulic system couples 2 hydrofoils and fulfills the fully flow‐induced oscillating motion. Two hydrofoils have a tandem spatial configuration because in such arrangement allows the turbine to reach a higher efficiency.

Backward swimming in elongated‐bodied abyssal demersal fishes: Synaphobranchidae, Macrouridae, and Ophidiidae

Journal of Fish Biology, Volume 107, Issue 1, Page 52-62, July 2025.
Abstract The deep‐sea demersal fish fauna is characterized by a prevalence of elongated‐body forms with long tapering tails. Using baited camera landers at depths of 4500–6300 m in the Pacific Ocean, we observed multiple instances of backward swimming using reverse undulation of the slender body in four species: the cutthroat eel Ilyophis robinsae ...
