What Data Should Robots Learn From? A Five‑Layer Data Pyramid Framework

The paper proposes a five‑layer Data Pyramid for embodied manipulation, analyzing each layer—real‑robot, UMI‑style, ego‑centric, simulation, and generic vision‑language data—through quality, diversity, reusability and physical fidelity dimensions, and discusses how these layers can be combined for training embodied AI models.
