Design and Kinetostatic Modeling of a Cable-Driven Schönflies-Motion Generator
Bibliographic record
Abstract
Abstract Cable-Driven Parallel Robots (CDPRs) use cables to move a moving-platform in space offering different advantages, such as high payload, reconfigurability, large translational workspace and high dynamic performances. However, their orientational workspace is usually limited due to cable/cable and cable/moving-platform collisions. In this paper, a novel Schönflies-Motion Generator (SMG) with a large translational workspace and a full rotation of its end-effector about a vertical axis is introduced. The full rotation of the end-effector is obtained using a parallelogram cable loop. It should be noted that the four degrees of freedom motion of the end-effector is controlled by four actuators fixed to the ground thanks to three parallelogram cable loops and a transmission system containing a differential mechanism. The kinetostatic model of the CDPR under design is expressed. The static workspace of the proposed Cable-Driven SMG (CDSMG) with three different cable arrangements is analyzed. Finally, a prototype of the CDSMG is presented and preliminary experimental results are discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
