Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

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,

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.

The 3 December 1988 Pasadena, California earthquake: Evidence for strike-slip motion on the Raymond fault [PDF]

, 1990
The Pasadena earthquake (M_L = 4.9) occurred on 3 December 1988, at a depth of 16 km. The hypocenters of the earthquake and its aftershocks define a east-northeast striking, steeply northwest-dipping surface that projects up to the active surficial trace

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.

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 ...

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.
