- What happened
- Researchers introduced HAF, a framework adapting general vision-language-action models to control humanoid robots performing complex locomotion and manipulation tasks simultaneously.
- Why it matters
- Roboticists building humanoid systems need coordination between walking, posture, and dual-arm control without retraining massive foundation models from scratch.
- Watch out
- Paper presents seven real-world tasks but does not compare against other recent humanoid control methods or discuss failure cases and safety constraints.

The patterns behind this
- Hierarchical Task Network (HTN) Planning
- Hierarchical Coordination
- Reinforcement Learning from Human Feedback
Each one covers how the technique works, when it earns its cost, and where it breaks.
