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.

Study on Calculation Model of Shale Fault Slip and Its Influencing Factors

Shiyou jixie, 2022
Fault slip in multi-stage fracturing of shale gas is the main factor leading to the shear deformation of casing in shale gas horizontal wells,which seriously affects the productivity of shale gas horizontal wells.However,there is no effective method to ...

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.

Fault slip, fault mapping, and age constrains along the North Olympic fault zone, Washington

, 2020
We reconstruct fault slip rates since ~14 ka on the Sadie Creek fault (SCF), north of the Olympic Mountains, Washington using airborne lidar and field mapping of surficial deposits and landforms and optically stimulated luminescence and radiocarbon ...

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.

Research on the Critical Mechanical Criterion for Stick‐Slip Instability of Mining‐Affected Normal Faults Based on the Rate‐and‐State Friction Law

Energy Science & Engineering
Mining‐induced disturbances cause stress imbalance in faults, leading to sudden stick‐slip events that trigger the rapid release of elastic energy and induce dynamic disasters in the surrounding rock.

Slip- and velocity-dependent friction measurements on Tohoku, Japan Trench samples

, 2020
We investigate the role of slow and transient slip as an initial condition on earthquake-hosting faults in laboratory friction experiments, using the natural fault material retrieved from the Tohoku décollement that likely hosts both fast and slow slip ...
