World Labs turns one robot task into thousands of sim worlds
Two research stories this morning: World Labs is betting that simulated worlds can replace expensive hardware time in robot training, and a new decomposition method promises to make model interpretability far cheaper. World Labs, the spatial-intelligence startup founded by Fei-Fei Li, says its Real-to-Sim-to-Real (R2S2R) engine can train robot policies entirely in simulation — with zero real-world training data — and then run them for hours on physical hardware.
