Abstract
Tensegrity mechanisms benefit from a reduced inertia due to their extensive use of cables and springs. However, they must be prestressed at all times in order to keep the cables in tension. For a given mechanism architecture, this is only possible in a specific set of configurations such that the analysis of these mechanisms is relatively complex. This paper presents the development and analysis of a new three-degree-of-freedom positional tensegrity mechanism that has a modular architecture. The mechanism, actuated by cables, has a relatively large workspace. For the special case where external and gravitational forces are neglected, solutions are given for the mech anism's equilibrium configuration both for given actuator positions as well as for a specified position of its effector. It is shown that the mechanism can be considered as an assembly of construction ele ments based on Snelson's X-shape tensegrity system and that these behave independently from one another.

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
