Bronchoscopy Robot with Enhanced Flexibility and Stability via Multi‐Segment Variable Stiffness Catheter

Advanced Intelligent Systems, EarlyView.
This work presents a magnetic bronchoscopy robot with a novel multi‐segment variable stiffness catheter. This catheter can not only move flexibly in the narrow bronchi but also harden according to the need to provide support. Combined with remote wireless magnetic field drive, it provides a more precise and effective solution for biopsy of deep lung ...

Small‐Scale Magnetic Peristaltic Soft Robot With Mobility and Transport Capabilities

Advanced Intelligent Systems, EarlyView.
This study introduces a miniature, untethered soft magnetic microrobot with peristaltic capabilities for both locomotion and cargo transport. Eight helically magnetized elastomeric strips deform under rotating fields (10–80 mT, 1–5 Hz), enabling movement across rods and lumina at up to 4.1 body lengths min‐¹.

Omnidirectional Shape Proprioception for Untethered Shape Memory Alloy‐Driven Soft Robotic Arms

Advanced Intelligent Systems, EarlyView.
A lightweight, modular soft robotic arm employs SMA actuation and a multi‐Hall‐magnet sensing system to achieve accurate omnidirectional shape proprioception. Each 35 g segment enables scalable assembly, while robust proprioception supports versatile navigation and manipulation in complex, unstructured environments.

Seasonal variation in wind speed and oceanic salt spray favors delayed reproduction in coastal yellow monkeyflowers

American Journal of Botany, EarlyView.
Abstract Premise The optimal timing of reproduction depends on the relative risk and benefit of continued growth. These risks and benefits depend on the local environment, which varies seasonally. While temperature and water availability are well‐studied selective agents on reproductive timing, less is known about other seasonally variable factors ...
