REWW‐ARM—Remote Wire‐Driven Mobile Robot: Design, Control, and Experimental Validation

open access: yesAdvanced Intelligent Systems, EarlyView.
The Remote Wire‐Driven robot “REWW‐ARM” demonstrates a new concept of remote actuation that separates electronics from harsh environments while retaining closed‐loop control. Combining tendon‐sheath mechanisms with decoupled joints, it achieves efficient power transmission and autonomous locomotion, manipulation, and underwater operation, suggesting ...

Myoelectric Origami‐Based Soft Robotic Knee Exoskeleton to Enhance Sit‐to‐Stand Assistance in Elderly Populations

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a lightweight Miura‐origami soft knee exoskeleton powered by vacuum actuation and integrated with a multimodal physiological intent‐recognition system, providing real‐time assistance during sit‐to‐stand movement to reduce muscle effort and improve user comfort.

A Neural Network‐Based Self‐Sensing Embedded Position Control System for Shape Memory Alloy Wire Actuators

open access: yesAdvanced Intelligent Systems, EarlyView.
Shape memory alloy wires exhibit thermally induced phase changes that generate actuation strain and resistance variations enabling self‐sensing. However, hysteretic electromechanical behavior complicates accurate state estimation. This paper presents an artificial in‐based self‐sensing method to reconstruct SMA actuator position in real time, achieving

A Noncovalent Click‐to‐Release Strategy to Control Bond Cleavage and Prodrug Activation

open access: yesAngewandte Chemie, EarlyView.
Extending the click‐to‐release concept beyond covalent ligation, we introduce a noncovalent click‐to‐release strategy based on cucurbituril‐adamantane (CB‐Ad) association. A supramolecular preassembly encapsulating a self‐immolative guest (SIG) is rationally designed to prevent premature release, while adding a high‐affinity Ad guest initiates the CB ...
