Versatile Rigid‐Flexible Coupling Modules: Enhancing Soft Origami Structures with Cable‐Driven Parallel Mechanisms

Advanced Intelligent Systems, EarlyView.
This work introduces a rigid‐flexible coupling building block by combining rigid parallel structures with soft origami structures. Through theoretical and experimental analysis, geometric parameters are optimized to achieve kinematic synergy between the two structures.

Enhanced Actuation Stress in Variable Stiffness Liquid Crystal Elastomers

Advanced Intelligent Systems, EarlyView.
Liquid crystal elastomers (LCEs) filled with low‐melting‐point alloy particles exhibit a fivefold increase in actuation stress and tunable stiffness. At low filler concentrations, mechanically enhanced network entropy boosts force output, while higher concentrations enable variable stiffness. This composite design mimics muscle‐like behavior, advancing

Self‐Organized Multitarget Pursuit in Multi‐Unmanned Aerial Vehicle Systems via Hierarchical Probabilistic Graphical Models

Advanced Intelligent Systems, EarlyView.
Multi‐UAV systems face challenges in adversarial environments due to limited adaptability and interpretability. This study proposes a self‐organized approach using hierarchical probabilistic graphical models with density‐driven parameter estimation.

Multiple Unmanned Aerial Vehicle Formation Control through Deep Reinforcement Learning with Offline Sample Correction

Advanced Intelligent Systems, EarlyView.
Herein, a deep reinforcement learning‐based multi‐UAV formation control approach is proposed. By optimizing the utilization of historical data through correcting of offline samples, the past experience is better leveraged and learning performance is improved.
