 Significant progress has been made in building generalist robot manipulation policies, yet their scalable and reproducible evaluation remains challenging, as real-world evaluation is operationally expensive and inefficient. We propose employing physical simulators as efficient, scalable, and informative complements to real-world evaluations. These simulation evaluations offer valuable quantitative metrics for checkpoint selection, insights into potential real-world policy behaviors or failure modes, and standardized setups to enhance reproducibility.
 
 This repository is based in the [SAPIEN](https://sapien.ucsd.edu/) simulator and the [ManiSkill2](https://maniskill2.github.io/) benchmark (we will also integrate the evaluation envs into ManiSkill3 once it is complete).
