AWS launches open-source Physical AI Toolchain combining its services with NVIDIA's stack

Amazon Web Services launched an open-source Physical AI Toolchain that combines AWS services with NVIDIA's Physical AI software to cover data generation, model training, simulation, edge deployment, and continuous improvement for robots. AWS uses Amazon SageMaker for training and AWS IoT Greengrass for distributing models to edge devices, while NVIDIA contributes Isaac Sim, Isaac Lab, Isaac GR00T, and Cosmos. The toolchain is hardware-neutral and does not directly replace RoboMaker, which was shut down in 2025.
