Overview

A PoC that digitally twins an entire shipyard in Isaac Sim to validate a robotic welding process before real-world deployment.

Project Background & Purpose

A proof-of-concept that builds an entire shipyard yard environment in NVIDIA Isaac Sim and validates a robotic welding process with a Sim2Real approach. A 6-axis robot detects weld seams on a ballast tank, plans its path from the WPS (Welding Procedure Specification), and carries out welding and inspection. Validating shipyard welding directly on-site with a real robot is costly and risky, so process timing, robot reachability, and weld sequencing needed to be verified without physical hardware first.

Components

• NVIDIA Isaac Sim / Omniverse digital-twin environment
• 6-axis welding robot
• WPS-based path planning module
• DES cell-level production scheduling
• MES/AAS real-time task-status sync

Process Steps

1. 1Build a digital twin of the shipyard and ballast tank in Isaac Sim
2. 2The 6-axis robot detects weld seams and plans its path from the WPS
3. 3Simulate the weld-and-inspect sequence while validating DES/MES integration
4. 4Transfer the validated path and schedule to the real site via the Sim2Real pipeline
