📄 RESEARCH

XPOLICYLAB: UNIFIED ROBOT POLICY EVALUATION STANDARD

  • XPolicyLab proposes a unified standard and open ecosystem to eliminate the O(N times M) integration problem, where connecting N robot policies to M evaluation environments currently requires separate integrations for each pair.
  • The system standardizes data representations, software interfaces, and runtime APIs to make robot policy evaluation and deployment modular and interoperable across the community.

VLA ADVERSARIAL ATTACKS VIA DIFFUSION

  • Researchers demonstrate that diffusion-generated unrestricted adversarial perturbations can compromise Vision-Language-Action models in physical manipulation settings, bypassing defenses that assume bounded perturbation norms.
