Abstract
This paper presents preliminary results on the design of a novel architecture of a three-phalanx underactuated finger. An ejection-free underactuated anthropomorphic hand is of the greatest interest for the field of humanoid robots. So far, all underactuated fingers lead to ejection for certain configurations. By using a second system of actuation in a three-phalanx finger, the zone of instability of this finger is reduced and the ejection problem is prevented. Hence, the mathematical model of this finger is first introduced, followed by the choice of transmission ratios to be taken for the two pulley systems. Finally, the zone of instability of this new architecture is presented where it is proved that ejection is avoided.

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
