Abstract
A series of human factors experiments involving maneuvering and grasping tasks are carried out to evaluate the effectiveness of a novel asymmetric semiautonomous teleoperation (AST) control design framework for teleoperation of mobile twin-arm robotic manipulators. Simplified configurations are examined first to explore control strategies for different aspects of such teleoperation tasks. These include teleoperation of a nonholonomic mobile base, telemanipulation of a dual-arm robot, and dual-arm/dual-operator teleoperation task scenarios. In two sets of experiments with a planar nonholonomic mobile base, teleoperation via a 3DOF planar haptic interface with position mapping and force reflection of the nonholonomic constraint decreases task-completion-time (TCT) and reduces unwanted collisions. In dual-arm and dual-operator teleoperation maneuverability experiments, the assignment of decoupled and nonconflicting control frames reduces TCT and unwanted contacts. The use of so-called "soft" constraints via passive semiautonomous control reduces TCT and unwanted block drops in telegrasping experiments with a twin-arm manipulator. A final comprehensive experiment encompassing elements of the simplified configurations demonstrates the effectiveness of AST control framework in dual-operator teleoperation of a twin-arm mobile manipulator.

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
