    "body_text": "MobiAgent uses high-level planning and visual reflection to compose atomic skills during mobile manipulation, while a second loop segments and verifies deployment rollouts for further training. Specialized control experts share a visual-language backbone. The authors report a 22.5-percentage-point gain over π0.5-TA on BEHAVIOR-1K, with recycled experience improving RoboCasa success from 7.5 to 27.5 percent and Astribot S1 success from 32.5 to 57.5 percent. The reported recovery and learning gains are bounded by those evaluations.",
