According to Fei-Fei Li (@drfeifei), Feature #4 in her thread outlines key manipulation state transitions for embodied AI and robotics, including spatial (next_to, inside, on_top, under, touching), particle coverage (covered, uncovered), thermal (hot, cooked, on_fire, frozen), and control/object states (open, closed, on, off, attached, sliced, diced) (source: Fei-Fei Li, X, Sep 2, 2025). The post provides a concrete taxonomy of task-relevant states for manipulation but includes no datasets, benchmarks, release timelines, companies, pricing, or any references to cryptocurrencies or blockchain integrations (source: Fei-Fei Li, X, Sep 2, 2025).
