This paper proposes a comprehensive framework for evaluating generalist robot manipulation policies, focusing on quantifiable sim-to-real transferability and robustness. The framework utilizes high-fidelity simulation, a systematic task taxonomy, and granular metrics to assess performance across diverse scenarios and perturbations.
Key insights
- High visual fidelity in simulation is critical for successful sim-to-real transfer, potentially enabling policies to transfer without additional real-world fine-tuning.
- Robot policies are highly vulnerable to even minor real-world perturbations (e.g., changes in lighting or camera pose), underscoring the necessity for systematic robustness evaluation.
- Moving beyond simple binary success rates to include granular metrics and a detailed taxonomy of failure modes is essential for precise diagnosis of policy shortcomings and fostering targeted advancements.
