Multilayer Biobased Poly(ethylene furanoate)/Graphene Oxide Nanofibrous Membranes With Directional Water Transport for Efficient Microplastics Filtration

Advanced Materials Technologies, EarlyView.
A self‐assembled multilayer biobased PEF/GO nanofibrous membrane was developed by electrospinning for efficient PLA microplastics (MPs) filtration. The membrane combines superhydrophilicity, directional water transport, mechanical robustness, and a synergistic size‐exclusion interception and electrostatic repulsion MPs separation mechanism, enabling ...

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

Advanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

Advanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Muscle Control of an Extra Robotic Digit

Advanced Robotics Research, EarlyView.
This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...
