ROSTDyn: Rover Simulation Based on Terramechanics and Dynamics
Journal of Terramechanics, 2013Abstract In recent years, rover-based planetary exploration missions have induced some new challenges related to both the speed and the fidelity of rover simulation. This paper introduces ROSTDyn (rover simulation based on terramechanics and dynamics), a good-fidelity (in a linear motion without side forces and related torques), real-time (with an ...

Volume 10: 19th International Conference on Multibody Systems, Nonlinear Dynamics, and Control (MSNDC), 2023
Abstract The trade-off between computational efficiency and accuracy of various terramechanics simulation methods is a challenge that many engineers face when conducting analysis of off-road vehicle mobility. The Discrete Element Method (DEM) can capture complex phenomena within the soil, but requires substantial time and computing ...

Mapping for Planetary Rovers from Terramechanics Perspective
2019 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2019In an autonomous scientific exploration system, the terrain map generated from mapping process integrates sensing information from multiple aspects and lays the base for decision making processes. With the increasing challenges in planetary exploration, equipping planetary rovers with the principles of terramechanics is becoming more and more common ...

Containerization Approach for High-Fidelity Terramechanics Simulations
SAE Technical Paper Series, 2023<div class="section abstract"><div class="htmlview paragraph">Integrated modeling of vehicle, tire and terrain is a fundamental challenge to be addressed for off-road autonomous navigation. The complexities arise due to lack of tools and techniques to predict the continuously varying terrain and environmental conditions and the resultant ...

Methods for generalization of experimental results in terramechanics
Journal of Terramechanics, 2019Abstract Due to the extreme variability of soils and different tillage and settling conditions, measurements made under a single set of conditions have little practical applicability under arbitrary conditions. Results of more general usefulness require systematic measurements to be carried out over suitable ranges of the main influencing variables ...

Terramechanics evaluation of low-pressure wheel on deformable terrain
2011 IEEE International Conference on Robotics and Automation, 2011In this paper new procedures for the measurement of mobility parameters, such as contact pressure, and an analysis of a low-pressure wheel model on deformable terrain, are presented. Because the lunar surface is covered by regolith which implies an irregular and rough terrain, the rover has difficulty in moving.
