Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

Journal of Field Robotics, Volume 43, Issue 3, Page 1884-1904, May 2026.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Dynamic Modeling and Control Strategy Optimization for a Hybrid Electric Tracked Vehicle

Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015
A new hybrid electric tracked bulldozer composed of an engine generator, two driving motors, and an ultracapacitor is put forward, which can provide high efficiencies and less fuel consumption comparing with traditional ones. This paper first presents the terramechanics of this hybrid electric tracked bulldozer.

Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Terramechanics of Mechatronic Locomotion for Subsurface Exploration: A 35-Year Technical Review on Soil–Structure Interactions, Friction-Reduction Mechanisms, and Engineering Design for Autonomous Planetary and Terrestrial Burrowing Robots

Technologies
Autonomous subterranean mobility remains one of the least unified domains in robotics because locomotion emerges from coupled interactions among deformable geomaterials, structural mechanics, energy dissipation, and environment-dependent sensing ...

Local particle refinement in terramechanical simulations

Journal of Terramechanics
The discrete element method (DEM) is a powerful tool for simulating granular soils, but its high computational demand often results in extended simulation times. While the effect of particle size has been extensively studied, the potential benefits of spatially scaling particle sizes are less explored.

Robotic Arm Geomechanical Experiments and Analyses to Enable Lunar Science and Settlement

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This study evaluates the capability of a robotic arm equipped with a force‐torque sensor and a specially designed scoop to perform geomechanical characterization of high‐fidelity lunar highlands regolith simulant. Experiments focused on pressure‐sinkage, shear strength, and angle of repose to assess the performance and applicability of the ...

A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

Journal of Field Robotics, Volume 42, Issue 7, Page 3772-3794, October 2025.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Mapped material point method for large deformation problems with sharp gradients and its application to soil‐structure interactions

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 48, Issue 9, Page 2334-2355, 25 June 2024.
Abstract The material point method (MPM) is often applied to large deformation problems that involve sharp gradients in the solution field. Representative examples in geomechanics are interactions between soils and various “structures” such as foundations, penetrometers, and machines, where the displacement fields exhibit sharp gradients around the ...
