Abstract

fetched live from OpenAlex

Accurate and efficient inverse kinematics transformations are required to accurately specify the Cartesian position and orientation of robotic manipulators. A novel algorithm is proposed which is accurate near singular points and is also stable at singular points and for targets which are out of the manipulator's reach. The algorithm uses the error-damped pseudoinverse to obtain stable joint corrections near singularities. Various strategies are presented to describe and handle the particular situations which arise near singularities.>

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
