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.

Identifying Physical Interactions in Contact‐Based Robot Manipulation for Learning from Demonstration

Advanced Robotics Research, EarlyView.
Robots can learn manipulation tasks from human demonstrations. This work proposes a versatile method to identify the physical interactions that occur in a demonstration, such as sequences of different contacts and interactions with mechanical constraints.

Mechanical behavior and micro-crack propagation mode of fault stick–slip under various roughness conditions

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Characterized by depressions and elevations, the rough surfaces of faults are prone to stress concentration and energy accumulation, leading to localized rupture in the upper and lower blocks. These regions are more susceptible to stick–slip instability,

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms

Advanced Robotics Research, EarlyView.
A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Moment tensor inversion of mining-induced seismic events and forward modeling of critical fault slip to prevent rockbursts

Journal of Rock Mechanics and Geotechnical Engineering
In this study, we employed Bayesian inversion coupled with the summation-by-parts and simultaneous-approximation-term (SBP-SAT) forward simulation method to elucidate the mechanisms behind mining-induced seismic events caused by fault slip and their ...
