Frontier signal stream

Boston Dynamics published a technical blog authored by Alberto Rodriguez, Director of Robot Behavior for Atlas, with research engineers Shane Rozen-Levy and Vinay Kamidi, explaining for the first time how Atlas learned to lift and carry unfamiliar objects without prior knowledge of their mass or centre of gravity. Training used GPU-parallel reinforcement-learning simulation across varied weights, friction and grip conditions; the published demonstration uses a 50-lb mini-fridge while internal testing exceeded 110 lb - above the training range - with the behaviour transferring to hardware without retraining (zero-shot sim-to-real).
