Abstract
We develop an autonomous navigation algorithm for a robot operating in two-dimensional environments cluttered with obstacles which can have arbitrary non-convex shapes and can be in close proximity with each other, under the assumption that there exists a safe path connecting the initial and the target locations. We propose a hybrid feedback controller, with Zeno-free switching between the move-to-target mode and the obstacle-avoidance mode, guaranteeing global asymptotic stability of the target equilibrium. To handle the obstacle non-convexity, we introduce a transformation that modifies (virtually) the obstacles’ shapes, in a non-conservative manner, to generate a modified free-space suitable for the design of a reliable obstacle avoidance strategy. Finally, we validate the efficacy of the proposed hybrid feedback controller through simulations.

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
