Towards Adaptive Wheel Geometry for Improved Rover Slippage Mitigation
Bibliographic record
Abstract
A challenge for rover systems is identifying wheel slippage, especially on deformable terrain such as sand or regolith. There are several approaches used to identify slippage, but, there is still a lack of tools for rovers to reduce or mitigate its effects. This paper investigates adaptive wheel grouser lengths based on virtual slippage measurements. We conduct two sets of experiments, the first evaluating the effect of uniformly extending grousers and the second on extending a section of grousers. Results from these experiments demonstrate that the ability to adaptively change the length of grouser based on virtual slippage measurements can significantly reduce slippage, offering potential improvements in rover traction and mobility. This paper demonstrates the concept of adaptive wheel mechanisms and paves the way for future development into adaptive wheel mechanisms. Future work will focus on adaptive wheel design and control strategies for multi-wheel rovers and further testing in real-world scenarios.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
