Illustration: Robots learn tasks better with demonstrations generated by a video model

In one line

Shared video-derived latent actions let one world model learn controllable visual dynamics across humans, robots, and simulations without matching their native control spaces.

Two ideas this paper builds on
Read it as

Videos show people and robots interacting, but robots use different commands, and human videos have no robot commands at all. A model trained with one robot’s controls may not transfer to another.

RynnWorld-Latent uses a “latent action,” a compact description of how a scene changes, inferred from video. It uses these descriptions to predict what happens next in a video, then can adapt to a target robot and generate training examples.

The model improved video predictions in the tested settings, and generated examples raised robot-controller success. This offers a way to reuse human, robot, and simulated experience without translating every platform into the same commands.
