Predicting how the environment changes over time is a key task in robotics, enabling all kinds of downstream tasks. Trace Anything is a very interesting look at how you can train models which predict the trajectory each point will take in the future โ you can use this for robot manipulation, video prediction, and more.

Modeling how environments evolve over time is an important aspect of interacting with them. Video world models have become an exciting area of research in robotics over the past year in part for this reason. What if there was a better way to represent changes over time, though?
Trace Anything represents each frame in a video as a trajectory field, i.e. a trajectory through 3d space. This provides a very unique foundation for all kinds of downstream tasks like goal-conditioned manipulation and motion forecasting.
We talked to Xinhang Liu to learn more.
