Abstract
We consider a mobile robot, modelled as a Dubins’ car, following a path. In the vicinity of the path is a human, modelled as an agile point mass, and a static obstacle. The robot’s objective is to follow the path unless it is absolutely necessary to deviate so as to avoid collision with the static obstacle or human. We seek to guarantee robot’s safety, even if the human is distracted or inattentive, and thus we consider worst-case motions for the human. The resulting problem takes the form of a reversed homicidal chauffeur game, but with the addition of a static obstacle. The static obstacle can interfere with the escape route of the robot, and thus fundamentally changes the form of the game. We propose a navigation algorithm for the robot that provably guarantees safety and that attempts to delay its reaction for as long as possible. We validate the proposed approach in simulation and provide a comparison to existing collision avoidance methods.

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
