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 ...

Gear‐Switch‐Integrated Dual‐Mode Three‐Wheeled Exoskeleton that Empowers Cyborg Insects with Enhanced Open‐Loop Locomotion Control Precision and Load Capacity

Advanced Intelligent Systems, EarlyView.
Cyborg insects’ low open‐loop control precision and limited sensor payload hinder applications. This article introduces an exoskeleton that improves motion precision and payload capacity. With a 7.2 cm × 14 cm size, it enhances load capacity to over 400 g and enables high‐precision movement without feedback control, expanding application scenarios for ...

Multi‐Module Micro/Nanorobots for Biomedical and Environmental Remediation Applications

Advanced Intelligent Systems, EarlyView.
Multi‐module microrobots (MNRs) have overcome the limitations of single‐module systems by integrating components such as propeller, actuator, manipulator, and imaging modalities. They show promise in biomedical applications, such as targeted drug delivery and tissue repair, as well as in environmental remediation, including pollutant removal.
