Abstract

fetched live from OpenAlex

In robotic finishing operations, the main challenge is to alleviate programming burdens and enhance accessibility for operators. Operators, often without programming skills, frequently need to redefine and modify finishing tasks due to variability in workpiece geometries, tool wear, and irregular features like weld spotters. This becomes more complicated when the operator must decide on redundant axes and part positions. Existing automation solutions often require highly skilled programmers and offline programming, which lead to delays and decreased productivity. This paper offers a novel approach for quasi-real-time autonomous planning of robot motion and workpiece setup. The objective is to propose an efficient and fast approach that optimizes finishing scenarios, including part setup and robot motions, with high success rates. The defined optimization problem is characterized by a non-linear, complex solution space with constraints like collision and joint limits, determining variables such as robot tool axisymmetry, external axes, and workpiece position and orientation. The objective function combines the robot condition number with the proximity of the home position to the task in the joint space. The proposed algorithm is seamlessly integrated within a ROS-based cyber-physical system and extensively validated across diverse test cases.

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.
