GAF: Gaussian Action Field As a 4D Representation for Dynamic World Modeling in Robotic Manipulation

Accurate scene perception is critical for vision-based robotic manipulation. Existing approaches typically follow either a Vision-to-Action V-A paradigm, predicting actions directly from visual inputs, or a Vision-to-3D-to-Action V-3D-A paradigm, leveraging intermediate 3D representations. However, …
