$\pi_{0.5}$: a Vision-Language-Action Model with Open-World Generalization

CoRL 2025oral

In order for robots to be useful, they must perform practically relevant tasks in the real world, outside of the lab. While vision-language-action (VLA) models have demonstrated impressive results for end-to-end robot control, it remains an open question how far such models can generalize in the wil…

π₀: A Vision-Language-Action Flow Model for General Robot Control

RSS 2025poster

Robot learning holds tremendous promise to unlock the full potential of flexible, general, and dexterous robot systems. However, bringing robot learning to the level of generality required for effective real-world systems faces major obstacles in terms of data, generalization, and robustness. In thi…

Deep RL at Scale: Sorting Waste in Office Buildings with a Fleet of Mobile Manipulators

RSS 2023poster

We describe a system for deep reinforcement learning of robotic manipulation skills applied to a large-scale real-world task: sorting recyclables and trash in office buildings. Real-world deployment of deep RL policies requires not only effective training algorithms, but the ability to bootstrap rea…

RT-1: Robotics Transformer for Real-World Control at Scale

RSS 2023poster

By transferring knowledge from large, diverse, task-agnostic datasets, modern machine learning models can solve specific downstream tasks either zero-shot or with small task-specific datasets to a high level of performance. While this capability has been demonstrated in other fields such as computer…

RT-2: Vision-Language-Action Models Transfer Web Knowledge to Robotic Control

CoRL 2023poster

We study how vision-language models trained on Internet-scale data can be incorporated directly into end-to-end robotic control to boost generalization and enable emergent semantic reasoning. Our goal is to enable a single end-to-end trained model to both learn to map robot observations to actions a…

Robots That Ask For Help: Uncertainty Alignment for Large Language Model Planners

CoRL 2023oral

Large language models (LLMs) exhibit a wide range of promising capabilities --- from step-by-step planning to commonsense reasoning --- that may provide utility for robots, but remain prone to confidently hallucinated predictions. In this work, we present KnowNo, a framework for measuring and aligni…

Do As I Can, Not As I Say: Grounding Language in Robotic Affordances

CoRL 2022oral

Large language models can encode a wealth of semantic knowledge about the world. Such knowledge could be extremely useful to robots aiming to act upon high-level, temporally extended instructions expressed in natural language. However, a significant weakness of language models is that they lack real…

Inner Monologue: Embodied Reasoning through Planning with Language Models

CoRL 2022poster

Recent works have shown how the reasoning capabilities of Large Language Models (LLMs) can be applied to domains beyond natural language processing, such as planning and interaction for robots. These embodied problems require an agent to understand many semantic aspects of the world: the repertoire…
