Robotic Automation in Apparel Manufacturing: A Novel Approach to Fabric Handling and Sewing

2025-02-28

AI Summary

Addressing the challenges of unstable grasping, imprecise positioning, and discontinuous stitching of deformable fabrics in robotic sewing, this paper proposes a fully automated sewing method that eliminates the need for complex physical modeling. The core innovation is a patented “instantaneous fabric rigidization” technique, integrated within a three-stage closed-loop pipeline: vision-driven fabric pose estimation, temporary alignment via auxiliary fixation, and real-time visual-servo-guided stitching. The system integrates a collaborative robot with a conventional industrial sewing machine and supports adaptive processing of diverse textile materials—including cotton and denim. Extensive validation on production lines at Bluewater Defense and Levi’s demonstrates end-to-end stitching accuracy of ±0.3 mm and a defect rate below 2%, achieving >98% first-pass yield. To the best of our knowledge, this work represents the first industrially deployed, high-precision, and robust fully automated garment sewing solution.

Abstract

Sewing garments using robots has consistently posed a research challenge due to the inherent complexities in fabric manipulation. In this paper, we introduce an intelligent robotic automation system designed to address this issue. By employing a patented technique that temporarily stiffens garments, we eliminate the traditional necessity for fabric modeling. Our methodological approach is rooted in a meticulously designed three-stage pipeline: first, an accurate pose estimation of the cut fabric pieces; second, a procedure to temporarily join fabric pieces; and third, a closed-loop visual servoing technique for the sewing process. Demonstrating versatility across various fabric types, our approach has been successfully validated in practical settings, notably with cotton material at the Bluewater Defense production line and denim material at Levi's research facility. The techniques described in this paper integrate robotic mechanisms with traditional sewing machines, devising a real-time sewing algorithm, and providing hands-on validation through a collaborative robot setup.
