    "body_text": "FetchMan begins with synthetic demonstrations across more than 150,000 scenes, then refines the cloned policy with Flow-GRPO and a sparse reward. The authors report 73.3 percent zero-shot success when a Unitree G1 walked toward and grasped a single target in unseen real scenes. The result supports the sim-to-real recipe for one reach-and-pick policy; it does not establish general household manipulation.",
