Lifeguard UAV System: Scout Quadcopter and Rescue Coaxial Hexacopter with In-Arm Pitch Axis for Extended and Symmetric Dual-Axis Tilt Rotor
Bibliographic record
Abstract
An Unmanned Aerial Vehicle (UAV) lifeguard system with scout and rescue UAVs is proposed and prototypes are demonstrated. For dynamic rescue operation, a novel symmetric in-arm pitch rotor tilt axis design is introduced for pitch angle extension by more than 65% over conventional end-arm pitch axis. The rescue UAV implements a coaxial hexacoptor with ±45 degree pitch angle and ±180 degree roll angle for dual-axis rotor tilt at each arm. The extended dual-tilt rotors will be able to adjust thrust to pull a victim to safety adaptively. The rescue UAV folds into itself three times to reduce its diameter by 45% for transportation in passenger vehicles. Its rotor tilting and initial flights were demonstrated. The scout UAV is a quadcopter that deploys an AI-capable mission controller, establishes triple radio channels for control redundancy, and increases payload capacity for a larger battery and a longer scout flight. Multiple autonomous beach flights were conducted to analyze beach hazards through image processing.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
