Terrain-Dependent Intra-Cycle Leg Timing for Effective Locomotion on Granular Slopes
Long Zhao, Xingjue Liao, Feifei Qian
Locomotion on granular slopes such as sand dunes remains a fundamental challenge for legged robots due to reduced shear strength and gravity-induced anisotropic yielding of granula…
Failure Mechanisms and Risk Estimation for Legged Robot Locomotion on Granular Slopes
Xingjue Liao, Feifei Qian
Locomotion on granular slopes such as sand dunes remains a fundamental challenge for legged robots due to reduced shear strength and gravity-induced anisotropic yielding of granula…
Scout-Rover cooperation: online terrain strength mapping and traversal risk estimation for planetary-analog explorations
Shipeng Liu, J. Diego Caporale, Yifeng Zhang +17
Robot-aided exploration of planetary surfaces is essential for understanding geologic processes, yet many scientifically valuable regions, such as Martian dunes and lunar craters,…
A bio-inspired sand-rolling robot: effect of body shape on sand rolling performance
Xingjue Liao, Wenhao Liu, Hao Wu +1
The capability of effectively moving on complex terrains such as sand and gravel can empower our robots to robustly operate in outdoor environments, and assist with critical tasks…
Multi-robot connective collaboration toward collective obstacle field traversal
Haodi Hu, Xingjue Liao, Wuhao Du +1
Environments with large terrain height variations present great challenges for legged robot locomotion. Drawing inspiration from fire ants' collective assembly behavior, we study s…
