Wheel–Soil Interaction Model for Rover Simulation and Analysis Using Elastoplasticity Theory
IEEE Transactions on Robotics, 2013A novel approach is proposed for the modeling of rigid-wheel and soft-soil interaction to efficiently compute normal and shear stress distributions in the contact area. The authors propose a velocity field in the vicinity of the contact area based on the physical nature of the problem. Thereupon, the incremental changes to the stress field are computed

An Apparatus to Measure Wheel–Soil Interactions on Sandy Terrains
IEEE/ASME Transactions on Mechatronics, 2018Wheeled mobile robots (WMR) have been deployed in Mars/Lunar exploration, military missions, and geological investigations, and they must handle rough and deformable terrains. The dynamics at the wheel–soil interface, including the wheel–terrain contact angle, wheel sinkage, and wheel–soil interaction forces and torque, are major factors in the ...

Experimental and simulation results of wheel-soil interaction for planetary rovers
2005 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2005The ability to predict rover locomotion performance is critical during the design, validation and operational phases of a planetary robotic mission. Predicting locomotion performance depends on the ability to accurately characterize the wheel-soil interactions.

Estimation of terramechanics parameters of wheel-soil interaction model using particle filtering
Journal of Terramechanics, 2018Abstract Accurate estimation of the parameters affecting the wheel-soil interaction terramechanics of an extraterrestrial rover is key to the success of its mission. Traditional approaches to estimating the relevant parameters based on laboratory tests lead to predictions that show significant deviation from experimental observations.

Wheeled mobile robots (WMR) are often applied to travel on outdoor unstructured environment, such as loose soil or variable field terrain. Learning the knowledge of terrain has played a significant role for better mobility and stability of WMR. In this study, a diagonal recurrent neural network-based adaptive method is proposed to identify terrain ...

A new dynamic testing system for wheel-soil interactions
2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015The vehicle trafficability on soft terrain is a key part of the overall vehicle performance. The field investigation and analysis show that lots of research has been done with no general theoretical law. The lack of real vehicle testing data holds back the development of wheel-soil interaction models to a great extent.
