## Summary

RoboDuo proposes a closed-loop dual-system framework that uses code as the interface between a coding agent and two VLAs: the coding agent writes programs that let a full-task VLA attempt the entire task and check whether it is complete; on failure, an atomic VLA completes the remaining steps.
