Design and Analysis for a Diving‐Beetle‐Inspired Swimming Robot with Multi‐Flexible Appendages

Advanced Intelligent Systems, EarlyView.
This article presents a bionic underwater robot inspired by the swimming behavior of diving beetles. The robot features flexible appendages and a specialized motion controller to mimic the beetle's swimming gaits. Extensive experiments show improved thrust, speed, and maneuverability.

A Study on Optimal Data Bandwidth of Recurrent Neural Network–Based Dynamics Model for Robot Manipulators

Advanced Intelligent Systems, EarlyView.
In this article, RNN–based learning method is proposed to achieve overall dynamic model of robot manipulators, which is established by optimal data‐bandwidth. The optimal data‐bandwidth is developed as a key behavior of the proposed method, which is designed on the loss function and its derivative.

A Wearable Soft Actuator for Directional Tactile Stimulation: Design and Testing

Advanced Intelligent Systems, EarlyView.
A wearable actuator able to produce directional tactile stimulation is obtained by embedding a planar shape memory spring in silicone matrix. The matrix is designed taking into account skin characteristics and leveraging its multifunctionality: it acts as a bias load, improves the thermal behavior of the spring and wearability.

Versatile Rigid‐Flexible Coupling Modules: Enhancing Soft Origami Structures with Cable‐Driven Parallel Mechanisms

Advanced Intelligent Systems, EarlyView.
This work introduces a rigid‐flexible coupling building block by combining rigid parallel structures with soft origami structures. Through theoretical and experimental analysis, geometric parameters are optimized to achieve kinematic synergy between the two structures.

SDSS-IV MaNGA: Spectroscopic Probes of Neutral Gas in Nearby Galaxies

The Astrophysical Journal
Cool, dusty interstellar material plays an important role in the chemical evolution of galaxies. We present an analysis of this material across galaxy type through a spatially resolved spectral stacking analysis of galaxies from the MaNGA survey.
