Abstract
Piezoelectric actuators are considered as standard structural elements in Microsystems Technology. A piezoelectric transducer conventionally works as a pure linear motor (piezotranslator). If a rotation is required from the piezoelectric transducer, a transmission mechanism must be designed. This article presents a study on the development of a novel two-degree-of-freedom piezoelectric rotary-linear actuator system, including (1) conceptual design, (2) dynamic modeling, (3) control, and (4) prototype. The experimental validation of these concepts was performed. The preliminary result of the experiment has shown that the proposed concept works very well; in particular, the system has achieved (1) the linear displacement resolutions: 26nm, (2) the angular displacement resolution: 0.019°, (3) the maximum driving force: 2.09N, and (4) the maximum driving torque: 12.20Nmm.

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
