An Aerial Robot Achieving Bimodal Flight and Independent Attitude Control through Passive Morphing

Advanced Intelligent Systems, EarlyView.
This article presents a bimodal aerial robot capable of operating in both standard quadcopter and revolving flight modes. With four rotors, it independently controls position and roll‐pitch attitude across five degrees of freedom. The design features passive revolute joints, allowing seamless mid‐air transitions between modes using centrifugal forces ...

Machine Learning‐Based Wind Classification by Wing Deformation in Biomimetic Flapping Robots: Biomimetic Flexible Structures Improve Wind Sensing

Advanced Intelligent Systems, EarlyView.
Strain gauges are attached to biomimetic flapping wings to investigate how wing strain sensors detect wind directions. A convolutional neural network model for wind direction classification is developed through experiments. The results reveal that wind classification is possible with strain data of only 0.2 flapping cycles, and the use of biomimetic ...

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 ...
