SyncWorld: Visual Calibration Enables World Models as Zero-Shot Simulators
SyncWorld is an action-conditioned world model acting as a zero-shot robotics simulator across unseen environments via visual calibration.
Researchers propose SyncWorld, an action-conditioned world model that simulates robot action outcomes in unseen environments without additional training. It uses a visual calibration episode of paired frames and actions to establish the setup-specific Action-Visual Mapping in context. Experiments show accurate simulation of action outcomes in novel settings and that simulated rollouts enable test-time policy improvement without training.
- Zero-shot simulator across unseen environments without extra training
- Visual calibration episode defines Action-Visual Mapping in context
- Learns to interpret actions through visual evidence under mixed training
- Simulated rollouts enable test-time policy improvement without training
- Addresses non-universality of actions in pixel space for robotics

World models are increasingly used as policy-in-the-loop imagination environments, where reliable rollouts require fine-grained controllability with respect to low-level robot actions.
