Autonomous geocaching: navigation and goal finding in outdoor domains
Bibliographic record
Abstract
This paper describes an autonomous robot system designed to solve the challenging task of geocaching. Geocaching involves locating a goal object in an outdoor environment given only its rough GPS position. No additional information about the environment such as road maps, waypoints, or obstacle descriptions is provided, nor is their often a simple straight line path to the object. This is in contrast to much of the research in robot navigation which often focuses on common structural features, e.g., road following, curb avoidance, or indoor navigation. In addition, uncertainty in GPS positions requires a final local search of the target area after completing the challenging navigation problem. We describe a relatively simple robotic system for completing this task. This system addresses three main issues: building a map from raw sensor readings, navigating to the target region, and searching for the target object. We demonstrate the effectiveness of this system in a variety of complex outdoor environments and compare our system's performance to that of a human expert teleoperating the robot.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
