Abstract
This paper focuses on the design and modeling of a prosthetic finger for children. Conventional prosthetic hands are simple grippers that only restore the very basic grasping capabilities of the human hand. Novel design methodologies are required in order to address the issue of low functionality of prosthetic hands while still meeting their mass and size requirements. We propose a biomimetic approach to prosthetic hand design. The musculoskeletal characteristics of the human hand are studied in order to extract elements that are essential in the design of a biomechanically accurate hand. This paper presents a 4 DOF finger design that closely mimics the size and kinematics of the human finger. Our design proposes to use SMA-driven tendon wires that are directly attached to the finger structure, in a manner similar to the natural tendons and muscles. A kinematic analysis of the proposed finger, which defines the relationship between the motion of its joints and the corresponding SMA artificial muscle contraction ranges, is presented. The results of a torque analysis, carried out to evaluate SMA wire diameter and actuation forces required, is also presented

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
