StreamingWAM: Streaming World Action Modeling via Chunk-Wise Staircase Flow Matching

World Action Models (WAMs), often built upon pretrained video-generation world models, have emerged as a promising framework for general-purpose and open-ended robot control. However, their real-world deployment often suffers from discontinuous and jerky execution. Existing methods typically address this issue by eithe...

Vision-TL-Action: Neuro-Symbolic Trajectory Generation from Visual Observations and Temporal Logic

Vision-TL-Action is introduced, which generates action trajectories from multi-view images, a coordinate-free TL syntax graph, and the robot initial state, demonstrating a direct mapping from visual observations and structured TL goals to action trajectories without requiring object geometry at inference.
