This work presents a robotic assembly system designed to automate the manufacturing process of electrolyzers, particularly the stacking of internal components divided into a set of 207 identical repeated cycles. The system integrates a digital twin in NVIDIA Isaac Sim for motion validation and task execution, and a UR10e robot arm with a tool-exchange system to handle rigid and deformable components with specifically designed pneumatic suction- and magnet-based grippers. A cycle of the repeated assembly order was evaluated, demonstrating significantly reduced cycle times compared to manual assembly. However, tool-exchange delays highlighted limitations in real-world execution. Future work will focus on scaling the system for industrial deployment.

摘要

This work presents a robotic assembly system designed to automate the manufacturing process of electrolyzers, particularly the stacking of internal components divided into a set of 207 identical repeated cycles. The system integrates a digital twin in NVIDIA Isaac Sim for motion validation and task execution, and a UR10e robot arm with a tool-exchange system to handle rigid and deformable components with specifically designed pneumatic suction- and magnet-based grippers. A cycle of the repeated assembly order was evaluated, demonstrating significantly reduced cycle times compared to manual assembly. However, tool-exchange delays highlighted limitations in real-world execution. Future work will focus on scaling the system for industrial deployment.
