Abstract

fetched live from OpenAlex

Abstract Welding is an important step in the manufacturing process of many products, yet traditional welding still requires intensive human labor and field welding in cold weather makes it more challenging. As robotic systems advance, they have become viable technologies for automating manufacturing processes in welding. Nevertheless, most existing robotic welding systems still rely on stationary robots and teach-playback programming mode. These limit the flexibility and adaptability of the robotic systems and requiring human intervention for setup, adjustments, and monitoring. Mobile manipulators have attracted researchers to incorporate into the robotics field owing to their variety of real-world applications, and mobile welding is one of the feasible applications. To address these limitations, a mobile welding robot (MWR) system is being developed for laboratory and field settings. This MWR system is equipped with a UGV (unmanned ground vehicle) with several sensors such as, LiDAR and an Inertial Measurement Unit (IMU), a six degree-of-freedom (DOF) robot manipulator, a 3D stereo camera, a flux core welder, and an onboard computer. The welding robot system is designed to navigate on uneven floors and outdoor construction sites autonomously, acquire 3D point cloud data of the workpiece, identify and segment the weld seams, perform automated manipulator path planning, and execute welding tasks with minimal human intervention. This research contributes to the field of robotic welding by developing an autonomous solution capable of operating in different environments, including laboratories, industry workshops, and outdoor with extreme weather conditions.

Full frame distilled prediction

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.
