Flow Policies as Actions of Skill-Level World Models: Learned and Symbolic Abstractions for Long-Horizon Planning
Submitted to the IEEE International Conference on Robotics and Automation (ICRA) 2027
A world model that steps over whole skills: each action is the input of a flow-matching policy, so one policy execution is one world-model transition. We compare four action abstractions, from a compressed noise seed to a symbolic label, under one world model and one planner, on block rearrangement tasks of up to 14 skills.
