MinCU: A Fine-Grained Benchmark for Grounded Minimal-Change Understanding in Image Pairs

Localizing and describing fine-grained differences between near-identical images is a critical yet underexplored capability for multimodal large language models (MLLMs). Existing benchmarks largely assess semantic comparison or single-image grounding in isolation, without jointly requiring faithful description and phys...

CARE: Experience-Guided Atomic Corrective Execution for Vision-Language-Action Policies

Vision-Language-Action (VLA) policies achieve strong performance in robotic manipulation but remain brittle once execution deviates from nominal trajectories. We propose CARE (Corrective Atomic Robotic Execution), a framework that improves recovery by learning from failures encountered during execution. Instead of gene...

MA-VLA: Multi-Arm Vision-Language-Action Model for Collaboration and Compositional Generalization

Multi-arm collaboration is becoming a core capability in embodied manipulation. Recent vision-language-action (VLA) models integrate perception, language, and control, but most represent language as a single global instruction and do not provide an explicit mechanism for assigning and composing arm-specific behaviors....
