Abstract
This paper presents the design of a discrete-time control algorithm for power line tracking and assisted landing of Hydro-Quebec's LineDrone robot, a multirotor unmanned aerial vehicle (UAV) designed to land on and roll along live power lines. The algorithm automatically aligns the UAV with the cable while the pilot remains in control of the vertical and longitudinal positions, hence facilitating landing by having fewer degrees of freedom on which the pilot must focus. Emphasis is placed on the design of the discrete-time control law, which results in a closed-form algebraic solution of gains for given transient specifications. The proposed control system is also designed to meet the requirements of operation near live lines, which means that the system is immune to electromagnetic interference. The proposed control algorithm is experimentally validated on LineDrone hybrid UAV under real outdoor conditions.

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
