See Selectively, Act Adaptively: Dual-Level Structural Decomposition for Bimanual Robot Manipulation

The paper frames the work as vlaModern Robot LearningVision-Language-Action model (VLA)A model that takes images and language as input and outputs robot actions.. Start here because it defines what success means and which assumptions the rest of the method inherits.

This paper shows how to build VLAModern Robot LearningVision-Language-Action model (VLA)A model that takes images and language as input and outputs robot actions. policies that handle two-armed robots by dynamically routing visual information based on taskCore ConceptsTaskThe job the robot is supposed to complete, such as pick-and-place, navigation, or drawer opening. relevance and decomposing actionCore ConceptsActionA command the robot sends to its motors, controller, or low-level system. generation into coordinated vs. independent arm modes. The result: 43% better real-world success on complex bimanual tasks like dual-arm assemblyManipulation & TasksAssemblyPutting components together in a structured way. compared to treating the robotCore ConceptsRobotA physical system with sensors and actuators that can observe the world and take actions. as a monolithic system.
