Abstract

fetched live from OpenAlex

This paper describes the use of space robotic manipulator that employs a visual servoing system in order to affect the dynamic capture of a non-cooperative target. The system uses photogrammetry in order to extract three-dimensional information from the twodimensional image of the camera and feeds the information to a Kalman filter. The information is propagated through an internal model of the system and performs a three step approach in order to capture a target in motion. The first step is the approach which aligns the gripper in the most likely orientation to result in a successful capture. The second is the capture which involves bringing the gripper within range and determining whether or not the target is within its grasp. The final stage is bringing the target to a relative halt with minimal force and disturbances to the target. The current approach employs a hybrid speedforce controller that limits the amount of force applied to the grasping bar of the target while propagating the speed and direction of the target in order to smoothly bring the target to a halt.

Teacher imitation

Not 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.
