NVIDIA's AI Agents Build Simulations by Talking to Omniverse Libraries

NVIDIA is demonstrating how frontier AI models, including GPT-6 Astra, can be directed through natural-language instructions to assemble, configure, and test 3D simulations using NVIDIA Omniverse libraries.

Key examples include: David Wehr used Astra to create an editable building model from panoramic photos and point-cloud measurements for warehouse planning; Pradeep Kaushik built a gas-turbine 'what-if' analysis app with Cantera thermochemistry and SciPy dynamics; Bhavik Sanganee scaled a warehouse simulation to 80 conveyors, 40 arms, and 800 boxes at 30 FPS in full HD before performance dropped when the scene doubled again; Oyindamola Omotuyi used Isaac Lab to simulate flexible cable routing for USB-C insertion; and Frank DeLise created a first- and third-person humanoid robot simulator.

For ABB Robotics YuMi, developers converted CAD files to OpenUSD with Astra, though NVIDIA noted physical properties in simulation were not calibrated against the real robot. A reusable autonomous driving environment, 'Zero to Alpamayo,' was built for testing sensor changes.

Builders care because this shifts simulation assembly from manual asset connecting and physics tuning to agent-guided natural language workflows, though performance bottlenecks in physics pipelines still require targeted investigation.
