NVIDIA's AI-driven robot training meets sim-to-real skepticism

NVIDIA's video describes Astra building training worlds from prompts and data, with Isaac Lab and Newton used to train robot skills before bringing them to a reference robot. A commentator argues that friction, sensor noise and unpredictable interactions complicate that move to physical machines. Gavriel State says Jensen Huang asked him to take charge of Isaac Lab in October 2024; he credits collaborators for work on Newton and Isaac Lab 3.0.
