Abstract
An undergraduate laboratory has been developed for a course in mechatronics that involves the control of a floating ping pong ball with a microprocessor. The apparatus consists of a ping pong ball located in a vertically oriented Plexiglas tube. At the top end of the tube, an ultrasonic transducer measures the position of the ball in the tube. A small cooling fan at the bottom end of the tube is used to control the height of the ball. Proportional-Integral-Derivative (PID) closed loop control is implemented by means of the microprocessor. In the laboratory, the students are required to program the microprocessor and conduct experiments in controller tuning. This paper describes a mechatronics laboratory that is easy to duplicate and exposes the students to various mechatronics issues.

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
