# Uranus: Building the Next-Generation Simulation Infrastructure for Embodied AI > Source: > Published: 2026-09-24 08:30:22+00:00 Scalable simulation is essential for robot data generation, policy training, evaluation, and safe iteration, yet real-world interaction is costly and conventional simulators require labor-intensive construction. We present Uranus, a data-driven robot simulator built around a joint-trajectory-conditi
