What Matters in Quality-Aware VLA Pretraining: A Benchmark and Empirical Study
Human teleoperators hesitate and take detours, and robot-model builders want to know whether tagging that sloppy data by quality helps. This preprint finds the gains are real but small and model-dependent, while plain simulation pretraining lifted real-robot success from 9.6% to 31.7%.
