CogWAM is a cognition‑guided world‑action model that links task reasoning with action learning via a persistent Semantic State, which records completed task events and the active subtask. The model updates this state only on semantic transitions, enabling task‑level context to persist across multiple action chunks. During inference, CogWAM removes the future‑prediction branch and directly generates actions from observations and the maintained state, achieving state‑of‑the‑art performance on RoboDojo and BiCoord and demonstrating efficient closed‑loop dual‑arm manipulation in real‑world experiments.

The paper introduces STEP, a State‑Aware Task Estimator and Planner that uses multi‑modal large language models to explicitly estimate system states and predict state transitions during task planning. By forecasting future states alongside actions, STEP reduces hallucinated actions and improves task‑convergent planning. In a simulated robot assembly task, STEP outperforms the state‑of‑the‑art by 32.8% in action executability and 14.8% in final‑state error.
