Reinforcement learning‐based finite‐time cross‐media tracking control for a cross‐media vehicle under unknown dynamics and disturbances

IET Control Theory &Applications, Volume 18, Issue 11, Page 1475-1490, July 2024.
A reinforcement learning framework is constructed to handle the unknown dynamics and environmental disturbances and achieve the optimal control performance. Combining the reinforcement learning technique, we develop the reinforcement learning‐based finite‐time control strategy without the singularity issue, which exhibits good robustness and provides ...

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.
