Agentic Real2Sim: Physics-based World Modeling with Vision-Language Agents
Summary
Agentic Real2Sim introduces a framework for generalized physical world modeling, converting real-world recordings of object-robot interactions into simulatable episodic twins. This system addresses the labor-intensive nature of real-to-sim conversion, which typically requires extensive manual tuning of visual foundation models, mesh cleanup, and coordinate-frame alignment. Agentic Real2Sim streamlines this process by recovering scene geometries, object states, inferring physical parameters, and assembling all necessary components for a runnable physical simulation. The framework is evaluated across rigid-object manipulation, deformable-object interaction, and humanoid motion scenes, demonstrating a first step toward scalable conversion. It utilizes an open-weight VLM backend, achieving comparable conversion success rates at a significantly reduced cost compared to frontier models, with the goal of supporting downstream robotics tasks like policy learning and evaluation.
Key takeaway
For robotics engineers and AI scientists struggling with labor-intensive real-to-sim conversion for object interaction, Agentic Real2Sim offers a streamlined, automated approach using vision-language agents. This framework significantly reduces manual effort and enables scalable creation of physics-based digital twins across diverse manipulation tasks. Consider integrating this framework to accelerate your policy learning and evaluation workflows, leveraging its cost-effective VLM backend for efficient simulation generation.
