Abstract
This paper proposes a trajectory generation and control strategy for generating stable gait subject to unknown disturbances, based on the concept of the Foot Placement Estimator (FPE). While most walking control strategies in the field of bipedal locomotion aim to constantly maintain balance, the Foot Placement Estimator (FPE) estimates where the foot must be placed in order to restore balance. One of the key novelties of the FPE approach is its natural extension to form complete gait cycles using a state machine and simple proportional-derivative controllers. In this paper, the FPE control strategy is extended from 2D to 3D robots, and demonstrated in simulation on a 14-DOF lower body bipedal robot.

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
