Consistent Manufacturing Device for Coiled Polymer Actuators
Bibliographic record
Abstract
Coiled polymer actuators are fabricated by heating a twisted nylon fishing filament. This paper provides a detailed review of their manufacturing process and proposes a method which manufactures these actuators consistently to improve the predictability of their behavior. Two devices are presented: a device that prepares consistent filament sections, and another that twists and coils the filament. Seven successful actuators are produced using the proposed method and compared with seven actuators produced using a method featured in other studies. The behavior of both sets of actuators is then compared using tensile tests on an Instron universal testing machine. The actuators manufactured using the device demonstrate a lower fail rate and produce more force on average. However, the average force produced by each actuator using the proposed method varied slightly. It is believed this fluctuation is due to inconsistent resistance wire lengths and the actuator end loop creation technique. Both of which would require additional improvement.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
