3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

open access: yesAdvanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.

Autonomous Charging and Battery Swapping for Unmanned Aerial Vehicles: A Review

open access: yesAdvanced Intelligent Systems, EarlyView.
This review evaluates major autonomous charging and battery swapping methods for unmanned aerial vehicles (UAVs) against a single question: how close each is to sustained unattended operation. Rather than ranking them by charging performance, it identifies the limitation that most restricts each method, and briefly outlines the supporting technologies ...

Space Pump: Repairable 3D‐Printed Bioinspired Pneumatic Peristaltic Pump for Fluid and Regolith Transport in Space

open access: yesAdvanced Intelligent Systems, EarlyView.
The space pump transports lunar regolith under vacuum condition. A fully 3D‐printed biomimetic peristaltic pump demonstrates reliable transport of liquids and solids using pneumatic ring actuators and flexible fused filament fabrication. The system operates under atmospheric and vacuum conditions, achieves high flow rates, and enables self‐priming ...
