Researchers have developed a new method called $R^3$ that trains vision-language models (VLMs) to reason in natural language for robotic manipulation tasks. This post-training technique involves mid-training a VLM on expert reasoning traces and then refining it with reinforcement learning from offline action data. The $R^3$ approach aims to enable robots to handle complex, long-horizon tasks by using free-form language reasoning to guide low-level policies, showing improved exploration and generalization compared to imitation learning baselines on benchmarks like Language Table and grocery packing.
