LIBERO-PeRM: Benchmarking Personalized Robotic Manipulation

LIBERO-PeRM is a benchmark for studying personalized robotic manipulation, focusing on how policies learn and follow user preferences in zero‑shot settings, from demonstrations, and across varying tasks and layouts. It introduces a taxonomy of language‑expressible preferences—motion, skill, and user‑profile choices—within the LIBERO simulation framework, generating 312 tasks with paired demonstrations and preference‑satisfaction metrics. Experiments reveal that current vision‑language‑action policies struggle with zero‑shot personalization, while supervised fine‑tuning improves learnability, yet challenges remain in generalization, decomposition, and conflict handling.
