Zero-Shot Long-Horizon Dexterous Manipulation via Multi-View 3D-Grounded VLM Reasoning

The paper frames the work as perceptionPerception & SensingPerceptionThe process of turning raw sensor data into useful understanding of the world.. Start here because it defines what success means and which assumptions the rest of the method inherits.
