Abstract
Humanoid robots have many potential applications in man-made environments, including performing hazardous tasks, assisting the elderly, and as a replacement for our aging workforce. However, generating a reliable gait for biped robots is challenging, particularly for dynamic gait and in the presence of unknown external disturbances, such as a bump from someone walking by. In this work, a 3D formulation of the Foot Placement Estimator is used with a high-level control strategy to achieve a dynamic gait capable of handling external disturbances. A key benefit of this approach is that the robot is able to respond in real time to external disturbances regardless of whether it is at rest or in motion. This strategy is implemented in simulation to control a 14-DOF lower-body humanoid robot being subjected to unknown external forces, both when at rest and while walking, and shown to generate stabilizing stepping actions.

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
