GE-Sim 2.0: A Roadmap Towards Comprehensive Closed-loop Video World Simulators for Robotic Manipulation

GE-Sim 2.0 is a closed-loop video world simulator for robotic manipulation trained on thousands of hours of real-world robot data covering teleoperation, contact-rich interaction, and on-robot policy deployment. Three new modules extend the base action-conditioned video generation framework: a state expert decoding proprioceptive state from video latents, a world judge scoring rollouts against task instructions for verifiable success signals, and a policy learning loop connecting simulation to VLA training.
