Spring and Power in Hovering Ornithopters
Advanced Intelligent Systems, EarlyView.Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

A Proactive Agent Collaborative Framework for Zero‐Shot Multimodal Medical Reasoning
Advanced Intelligent Systems, EarlyView.This work proposes a multimodal medical collaborative reasoning framework, which imitates clinician's working patterns of comparative analysis. The framework includes a cohort of domain‐expert models, and an large language model learner agent to generate inquiries and interact with these experts to gather the essential information, and integrate the ...

Advanced Intelligent Systems, EarlyView.6D object pose estimation is a critical component in computer vision domain. A deep bidirectional fusion network is developed, DBF‐Net, which achieves accurate 6D object pose estimation using a single RGB‐D image. DBF‐Net effectively extracts and fuses geometric and appearance features from input data.

Treecreeper Drone: Adaptive Mechanism for Passive Tree Trunk Perching
Advanced Intelligent Systems, EarlyView.Taking inspiration from treecreepers, a passively triggered aerial robot that can reliably perch on vertical tree trunks is presented. The friction‐based approach combines a microspine array with a tail‐like support, and then validates via dynamic analyses and flight experiments, ensuring stable performance across trunk diameters and bark textures ...
