A Soft Robotic Morphing Wing for Unmanned Underwater Vehicles

Advanced Intelligent Systems, Volume 6, Issue 6, June 2024.
This study presents the design and hydrodynamic characterization of a soft wing for implementation on underwater gliders. Through hydraulic actuation, the soft wing deforms and adjusts its lift‐to‐drag ratio, which ranges from −70% to +10% with respect to a rigid wing.

Does Bistability Improve Swimming Performance in Robotic Fish?

Advanced Intelligent Systems, Volume 6, Issue 6, June 2024.
This study asks whether bistability is a fundamentally useful feature of swimming mechanisms, or simply a tool to overcome actuation limitations. It quantifies the effects of introducing bistability into a simple bioinspired propulsion system with variable morphology.

Use of an unmanned aerial‐aquatic vehicle for acoustic sensing in freshwater ecosystems

Remote Sensing in Ecology and Conservation, Volume 10, Issue 3, Page 343-359, June 2024.
In this article, we integrate water surface and underwater acoustic monitoring equipment onto a prototype unmanned aerial‐aquatic vehicle (UAAV) capable of sailing and flight (SailMAV), to demonstrate how robotics can facilitate acoustic sensing in freshwater ecosystems. Results show higher species richness and call abundance from UAAV surveys and high
