Abstract
This paper presents a position tracking system which estimates the position of the tip of a fastening tool. The proposed system uses a Kalman filter (KF) and particle filter (PF) combination to synthesize measurements from an inertial measurement unit (IMU) and a position sensor. The KF part is used to estimate the position of the centre of mass of the tool, and the PF is used to estimate the orientation of the tool. In addition, a rule-based logic system is used to reduce angular velocity measurement error and identify the fastening action of the tool. The proposed system was validated experimentally using various scenarios representative of assembly tasks in a factory environment. The experiment results show that the proposed system can accurately identify the fastened bolt even when the angular velocity measurement is not accurate provided that a large enough number of particles is used. In addition, even when there are multiple possibilities for fastened bolt positions, the experimental results show that the proposed system can correctly identify the fastened bolt by utilizing the accumulated position error of each particle.

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
