Abstract
In this paper, the rolling stability of a power-generating tumbleweed rover is investigated. The nonlinear equations of motion of the rover capture the nonholonomic nature of rolling without slipping, the external wind force, and energy dissipation due to rolling friction and power generation. To assess stability of the system as it rolls about a preferred axis of rotation, Lyapunov’s indirect method is employed. When the shell of the tumbleweed rover has a uniform mass distribution, Lyapunov’s indirect method predicts instability; when the inertia about a preferred axis of rotation is increased, Lyapunov’s indirect method predicts stability. Numerical simulation results of both the linearized and nonlinear equations of motion confirm both the instability and stability predictions of Lyapunov’s indirect method.

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 it
