Bronchoscope Tip Localization With Learned Airway Constraints and an Open Source Simulator

Advanced Intelligent Systems, EarlyView.
BronchoLoc addresses feature‐poor bronchoscopic imaging by combining monocular video with a preoperative CT graph to estimate 3D camera location. A local tracker identifies candidate branches, while a sequence‐aware global module refines the trajectory. Demonstrating sub‐centimeter accuracy across synthetic and phantom datasets, this framework advances

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

Advanced 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.

A Hierarchical, Model‐Based System for High‐Performance Humanoid Soccer

Advanced Intelligent Systems, EarlyView.
A hierarchical model‐based humanoid soccer system built on ARTEMIS integrates compliant mechanism design, in‐gait kicking, perception, localization, collision‐aware navigation, and behavior planning. Hardware–software codesign aligns mechanical design and control strategy with the requirements of autonomous soccer.

Hybrid Granular–Elastomer Jamming With Confinement‐Mediated Stiffening

Advanced Intelligent Systems, EarlyView.
A granular–elastomer hybrid jamming medium enables isotropic, repeatable stiffness modulation by exploiting vacuum‐induced confinement of an elastomeric network rather than particle friction. The actuator supports large 3D deformations (bending, folding, and twisting), retains programmed shapes when unjammed, and achieves an ~8× stiffness increase and ...

Environmentally Symbiotic Plant Robot

Advanced Intelligent Systems, EarlyView.
An environmentally symbiotic plant robot is presented that externalizes its drive system to plants and soil. By converting germination and growth forces into locomotion, the robot sustains a closed cycle of seeding, germination, growth, and reseeding, autonomously traveling on soil for 30 days using only environmental resources while distributing seeds
