An interface-centric taxonomy is proposed to categorize methods for learning robotic manipulation interfaces from action-free temporal video, analyzing how video-derived temporal structure connects to robot control. This survey identifies the "robotics integration layer" as a critical bottleneck in translating visual predictions into dependable robot actions.
Key insights
- The proposed interface-centric taxonomy successfully structures diverse methods into three families (Direct Video–Action Policies, Latent-Action Methods, Explicit Visual Interfaces), revealing recurring design patterns and inherent trade-offs in connecting video to robot control.
- The choice of interface design fundamentally dictates how robot control loops are closed, where physical inconsistencies typically emerge, and the opportunities available for pre-execution verification.
- The "robotics integration layer," encompassing the mechanisms for grounding video predictions to reliable robot actions, maintaining adequate control rates, ensuring physical feasibility, and enabling robust failure recovery, is the most critical unresolved challenge.
