DiagGen: Agentic Generation of Deformable Assets with Sim-based Diagnostics for Robotic Simulation

DiagGen is presented, an agentic framework that turns a single in-the-wild image into a simulation-ready deformable asset through a generate--simulate--diagnose--refine loop, and shows that diagnostics provides useful repair cues and can moderately improve the quality of generated deformable assets.

Agentic Real2Sim: Physics-based World Modeling with Vision-Language Agents

Agentic Real2Sim is introduced, a framework for generalized physical world modeling with vision-language agents, converting a real-world recording of object-robot interaction into a simulatable episodic twin which preserves observations, geometries, robot interactions, and object states.

JEPA-x: Cross-Predictive Physics Grounding for Forecastable Latent Dynamics

This work introduces the cross-predictive JEPA (JEPA-x), which grounds latent dynamics in privileged physical trajectories, and shows that direct physical-state regression improves decodability without improving forecastability or control, indicating that the benefit comes from shaping latent dynamics rather than merel...
