Translating semantic task understanding into executable robot actions

Determine a general and practical mechanism to translate high-level semantic task understanding into executable physical robot manipulation actions, bridging the gap between task reasoning and low-level control across diverse tasks and embodiments.

Background

The paper discusses modular robotics systems that use large pretrained models to perform task understanding, while traditional control methods handle execution. Although prior approaches can generate high-level plans, affordance maps, or semantic keypoints, they often require predefined skill primitives or learned policies from demonstrations to convert understanding into actions—reintroducing data bottlenecks and limiting generalization.

Within this context, the authors explicitly note that the core challenge of mapping semantic understanding into physical robot actions remains unresolved. NovaFlow is proposed as a step toward addressing this gap by distilling generated videos into actionable 3D object flow, but the broader problem of general translation from semantic understanding to control is highlighted as open.
