NVIDIA advances OpenUSD and Halos for robotaxi safety
NVIDIA outlined OpenUSD, Omniverse libraries and the Halos framework to support safer robotaxis and physical AI systems.
NVIDIA said it is deploying new OpenUSD and Omniverse technologies to link real-world data, high-fidelity simulation and AI models for physical AI development.
The company said in a statement that the OpenUSD Core Specification 1.0 defines standard data types, file formats and composition behaviors to enable predictable, interoperable USD pipelines. It added that NVIDIA Omniverse libraries combine RTX rendering, physics simulation and efficient runtimes to produce digital twins and SimReady assets for synthetic data generation and testing.
The company said SimReady assets can be loaded directly into NVIDIA Isaac Sim, where USDPhysics colliders, rigid body dynamics and composition-arc–based variants allow teams to test robots in virtual facilities mirroring real operations. The firm also noted the Learn OpenUSD curriculum is now open source on GitHub to let contributors localize and adapt training materials.
NVIDIA described generative world techniques such as Gaussian splatting and the Play4D pipeline for faster, higher-fidelity dynamic scene rendering, and cited World Labs’ Marble model and Omniverse NuRec for turning prompts and images into physics-ready 3D environments. The company highlighted Lightwheel’s SimReady asset library, the Sim2Val framework developed with Harvard and Stanford researchers, and a NuRec Fixer model for improving neural reconstructions.
NVIDIA said the Halos AI Systems Inspection Lab, accredited by ANAB, offers impartial inspection and certification through the Halos Certification Program, and named Bosch, Nuro and Wayve among early participants. The company said Onsemi has passed the lab’s inspection and noted integrations with CARLA, Voxel51 and Mcity’s 32-acre AV test facility to align real sensor recordings with simulated data.
The Recap
- NVIDIA detailed OpenUSD and Omniverse tools for physical AI.
- OpenUSD Core Specification 1.0 underpins reusable SimReady asset pipelines.
- NVIDIA Halos lab offers inspection and certification through Halos program.
