This study establishes a unified framework for assessing sim-to-real transfer in vision-language-action (VLA) systems, offering practitioners concrete guidance on when simulator-based fine-tuning effectively aligns with real-world performance. By systematically analyzing policy ranking consistency and failure patterns across diverse platforms, the work identifies specific simulation signals that reliably predict deployment outcomes. Ultimately, it provides a critical benchmark for evaluating the utility of current robotics simulators versus the need for more realistic perturbation modeling.
A Practical Recipe Towards Improving Sim-and-Real Correlation for VLA Evaluation
arXiv:2606.10366v1 Announce Type: new Abstract: Simulation has become an essential tool for evaluating and improving vision-language-action (VLA) policies, offering scalable, reproducible, and controllable alternatives to costly real-world robot evaluation. Recent simulation benchmarks have made substantial progress on realism and diversity, yet these platforms have not been widely adopted as reliable proxies for real-world policy evaluation. In this work, we investigate this issue through the lens of sim-and-real correlation. We conduct a systematic study across multiple simulation platforms, VLA policies, tasks, and perturbation factors, measuring whether simulated evaluation preserves real-world conclusions in terms of policy ranking consistency, performance correlation, and perturbation-wise failure patterns. This analysis allows us to characterize the limitations of existing simulators and identify what kinds of simulation signals are more aligned with real-world deployment. We further examine how users should exploit simulation for policy improvement, including when simulator-based finetuning is beneficial and how the amount of post-training data affects sim-and-real alignment. Overall, our work provides a unified framework for measuring, interpreting, and improving the usefulness of simulation for VLA policies, offering guidance both for simulator designers and for practitioners who use simulation as part of the policy development pipeline.
