Abstract
Visual teach-and-repeat navigation enables long-range rover autonomy without solving the simultaneous localization and mapping problem or requiring an accurate global reconstruction. During a learning phase, the rover is piloted along a route, logging images. After post-processing, the rover is able to repeat the route in either direction any number of times. This paper describes and evaluates the localization algorithm at the core of a teach-and-repeat system that has been tested on over 32 kilometers of autonomous driving in an urban environment and at a planetary analog site in the High Arctic. We show how a stereo visual odometry pipeline can be extended to become a mapping and localization system, then evaluate the performance of the algorithm with respect to accuracy, robustness to path-tracking error, and the effects of lighting.

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
