The Dyna-2.1 author explains why RL powers the low-level (System 0) controller of wheeled semi-humanoids: dynamics-aware tracking that stays compliant and robust to infeasible commands, human-trajectory priors over natural whole-body postures enabling simple objectives, and faster teleop task completion as a direct result.
