3D robot simulator preprint reports visual and tactile prediction at 50 Hz

Researchers report in an arXiv preprint that their 3D World Simulator predicts appearance, geometry and tactile observations at 50 Hz in experiments. The system models how robot actions change a shared three-dimensional scene, supporting consistent views from different camera positions. The framework compresses point clouds into a compact representation of three-dimensional space, then predicts how that representation evolves in response to actions. The researchers demonstrate data generation for robot policy training and evaluation using touch and multiple camera views. They also demonstrate planning with unseen objects and robot configurations; the reported capability remains experimental.
