D-Robotics Opens World-Model Simulator Uranus for Robot Policy Testing
D-Robotics, a Chinese robotics company, has published the technical report for its world-model simulation platform Uranus and released inference code, an SDK and two versions of model weights, while offering 100 early-access slots to developers and researchers worldwide. The platform is designed to let robot policies run, test and compare actions in a virtual environment. Uranus uses future joint trajectories as conditions and an autoregressive diffusion architecture to generate multi-view observations corresponding to robot actions, forming a closed interaction loop for policy evaluation. D-Robotics said Uranus supports single-arm, dual-arm and mobile manipulation robots under one model by converting different robot bodies into a unified skeleton and spatial representation. Camera inputs are encoded using Plücker ray embeddings, and the model fuses...
