Abstract
Two novel architectures of planar spring-loaded cable-loop-driven parallel mechanisms that do not require actuation redundancy are introduced in this paper. In order to avoid redundancy in the cable-driven parallel mechanisms and require only N actuators to control N-DOF motion, a new spring-loaded cable-loop-driven mechanism is proposed. By attaching springs to the cable loops, two degrees of freedom can be controlled using only two actuators and spools are eliminated in this mechanism. Therefore, the control method can be simplified compared with conventional cable-driven mechanisms making use of spools and actuation redundancy. The mechanisms can be actuated using either linear sliders or rotary actuators driving the motion of a cable or belt loop. Kinematic and static analyses are presented for the new architectures. It is verified that the cables and springs can be kept in tension within a certain workspace. Results of numerical simulations are also given in order to provide insight into the design 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
