SceneSmith: Agentic Generation of Simulation-Ready Indoor Scenes

ICML 2026spotlight

Simulation has become a key tool for training and evaluating home robots at scale, yet existing environments fail to capture the diversity and physical complexity of real indoor spaces. Current scene synthesis methods produce sparsely furnished rooms that lack the dense clutter, articulated furnitur…

Empirical Analysis of Sim-and-Real Cotraining of Diffusion Policies For Planar Pushing from Pixels

IROS 2025

Cotraining with demonstration data generated both in simulation and on real hardware has emerged as a promising recipe for scaling imitation learning in robotics. This work seeks to elucidate basic principles of this simand-real cotraining to inform simulation design, sim-and-real dataset creation,

Scalable Real2Sim: Physics-Aware Asset Generation Via Robotic Pick-and-Place Setups

IROS 2025

Simulating object dynamics from real-world perception shows great promise for digital twins and robotic manipulation but often demands labor-intensive measurements and expertise. We present a fully automated Real2Sim pipeline that generates simulation-ready assets for real-world objects through robo
