Abstract

fetched live from OpenAlex

View Video Presentation: https://doi.org/10.2514/6.2023-0510.vid The ability to detect and characterize the onset of wheel slippage is crucial for rover operations. This paper presents a new method for defining wheel slippage by considering the size of a virtual wheel that produces the amount of forward motion obtained. From this definition, we consider the implications of this virtual wheel on proprioceptive measurements. Then, by using cross-correlation, we can identify the onset of wheel slippage. Using these observations, we construct a simple 3-layer Feed-Forward Neural Network to identify wheel slippage using the classical definition of slippage and our new virtual wheel size. We compare four networks trained on experimental data obtained from our rover test sandbox and compare the results of the networks on unseen data sets. The networks we trained are able to estimate slippage values to approximately ±0.1 using the classical definition of slip and ±0.4���� of a change in wheel radius using our new definition of slippage (one-sigma bound).

Full frame distilled prediction

Teacher imitation

Not 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.
