Xilun Zhang, Maggie Wang, Erik Bauer وآخرون · 2026

Vision-language-action (VLA) policies trained on large datasets are capable within their training domains, yet they still fail to generalize to the variety of situations a robot meets in real-world deployment. Agentic robot systems complement the policy with a vision-language model (VLM) orchestrator that learns when t …

LIBERO-MAX: Do Robot Policies Adapt When the World Changes?

Yunbei Zhang, Zijian Jin, Yuanzhe Liu وآخرون · 2026

Robots must often continue a task after a target moves, the viewpoint shifts, or an obstacle appears, even though their earlier observations and committed actions reflect the previous scene. Many simulation robustness benchmarks fix external conditions at reset, leaving this temporal challenge underexamined. We introdu …
