Stair‐Climbing Wheelchairs for Enhanced Mobility: A Comprehensive Review of Fundamental Mechanisms, Design Concepts, and Performance Analysis

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

An Enhanced Soft‐Containing Gripper for Pick‐And‐Place of Oyster Products at Extreme Handling Speed

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Soft robotic grippers have been developed for high‐speed handling of soft, fragile foods. For example, our previously designed soft‐containing gripper has been implemented on food production lines. However, existing soft robotic grippers remain inadequate for food pick‐and‐place tasks at extreme handling speeds (e.g., > 70 pcs/min).

A Compact Annular Electrostatic Clutch Joint: Dynamic Response Modeling and Time‐Sharing Control for Underactuated Robots

open access: yesSmartBot, EarlyView.
Electrostatic clutches offer programmable variable stiffness for multi‐DOF robots, but their continuous motion is usually bottlenecked by spatial constraints and detachment delays. Here, the authors report a compact annular electrostatic clutch joint with a biphasic amplitude‐frequency modulation strategy to rapidly mitigate residual polarization ...

Multi‐Scale Magnetically Controlled Soft Matter Robots for Tissue Interfacing Applications

open access: yesSmartBot, EarlyView.
Magnetically controlled soft matter robots (MSMRs) integrate remote magnetic control with soft matter adaptability for minimally invasive biomedical tasks at tissue interfaces across multiple scales. This review examines the interaction mechanisms between MSMRs and tissue interfaces, with MSMRs classified into five categories according to their ...

Super‐Electron‐Donor Polymers: From Monomer Design to Redox Functionality

open access: yesSmall, EarlyView.
2,2'‐Bipyridinylidenes are known for their “super‐electron‐donor” properties and have therefore been used beyond the field of organic synthesis. Their two‐electron redox process at a low potential of 1.8 V vs. Li/Li+ makes them attractive negative p‐type electrode‐active materials.
