A 35-page survey by Chef Robotics' Inkyu Sa covering 200+ sources and 31 methods from a production-floor perspective. It organizes bimanual VLA research by 'coupling tightness × action-head emission,' argues flow-matching heads with action chunking are the strongest dual-arm recipe (winning on ~10 integration steps), and dissects the two-orders-of-magnitude gap between benchmarks and real deployment plus three durable gaps (force, evaluation, data).
