Evaluation of the shear deformation model in the process of wheel sinking by the wheel experiment
Nihon Kikai Gakkai ronbunshu, 2015 Soft soils cover on planetary surfaces, so the wheels for exploration rovers easily slip. Understanding an interaction between a wheel and soft soils is important for a traction control to improve rover traversability.

Parameters Identification of Tire–Clay Contact Angle Based on Numerical Simulation
MachinesThe predictive accuracy of the Bekker–Wong model for wheel traction is highly dependent on the precision of the wheel–soil contact angle parameters. These parameters are typically identified through extensive and costly single wheel–soil tests, which are

International Journal of Advanced Robotic Systems, 2014 This paper presents a grouser developed for the wheels of lunar exploration rovers to measure sinkage. The wheels, which are intended to traverse loose soil such as lunar regolith, contain grousers that transfer thrust to the wheels and thus to the body ...
