Quan Vuong and Jost Tobias Springenberg from Physical Intelligence (PI) discuss their mission to create a universal model for controlling any robot. They detail their approach, which centers on Vision-Language-Action (VLA) models, a purpose-built data engine for scaled data collection, and the evolution of their models toward open-world generalization.
Developing general-purpose robots requires a shift from specialized, single-task systems to broad foundation models. This is achieved through a combination of large-scale, diverse, real-world data collection and a specific training methodology: pre-training on all available data and then fine-tuning on a curated, high-quality subset of demonstrations. This recipe, combined with architectural innovations to preserve the capabilities of Vision-Language Model (VLM) backbones, enables robots to perform complex, long-horizon tasks, generalize to unseen environments, and respond to open-ended human instructions.
André Prager, former Chief Engineer at Wing, discusses the core engineering philosophy of simplicity and cost-effectiveness that enabled the drone delivery service. He covers the design of key systems like the passive charging pad, the intelligent winch, the non-powered autoloader, and the iterative process of making the drones acoustically unobtrusive.
