Abstract
This paper describes the design of a one-person hydraulic motion simulator with six degrees of freedom. An inverted, ceiling-mounted Stewart platform design enables the use of narrower hydraulic cylinders than required with floor-mounted designs, and significantly reduces hydraulic flow requirements and hence the cost. The paper details the platform geometry, shows the effectiveness of Newton's method in solving the direct kinematics, and describes a tested hydraulic system design. Issues of control and safety are also addressed. It is expected that this motion simulator will provide 9.8 m/s/sup 2/, 400/spl deg//s/sup 2/ accelerations and 1 m/s, 30/spl deg//s speeds to a 250 kg payload with 1 m, 45/spl deg/ displacements from a nominal center. Preliminary experiments at low-pressure have been encouraging.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
