Abstract
The authors report on the analysis and experimental evaluation of a parallel Schönflies-motion generator (SMG) intended for fast pick-and-place operations and actuated with cylindrical drives (C-drives). Its CRRHHRRC isostatic architecture offers high rotability of the moving platform and a reduced number of limbs, as compared to robots available on the market. A simulation model using the dynamics of the robot as well as an experimental prototype are described. The results obtained are used to assess the pros and cons of two alternative C-drive architectures.A workspace analysis including the feasible wrenches is conducted. The industry standard Adept test cycle is used to evaluate the performance of the prototype. The data obtained prove that C-drives augmented with strain-wave gears give the SMG significantly better wrench capabilities and lower trajectory-tracking error, compared to their alternative C-drives based on cables.

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
