Abstract
The design of a link-less hyper-redundant miniature manipulator driven by high strain SMA (shape memory alloy) actuators is the focus of this research. The manipulator is composed of four identical modules connected in series, each providing three degrees of freedom from three symmetrically positioned actuators. The manipulator is withheld by the action of a positive air pressure flow injected in structure at the base of the manipulator. The internal pressure give the manipulator its stiffness, provides the return force require by the SMA actuators and, to a certain extent, acts as a coolant during post-actuation. High strain rates are achieved by submitting the SMA material to bending stressed rather than pure tension. The controller is designed based on the principle of binary actuation, which eliminates the need for sensing equipment and feedback control. The compliant nature of the manipulator and its lightweight construction enable the manipulator to perform complex tasks in constrained environments

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
