Researchers have introduced Action Map Policy (AMP), a novel approach to robot learning that frames 3D closed-loop manipulation as an image-space classification problem. This method projects 3D actions onto camera image planes, treating each pixel as a discrete class to manage dimensionality and retain multi-modality. AMP achieves millimeter-level precision for high-dimensional actions without an excessively large vocabulary, enabling faster inference than diffusion policies and demonstrating superior success rates and spatial reasoning in experiments.
