Robots traversing 9 meters high: ZeeBot fleet runs 3.3 marathons in a warehouse during peak season

During the 2026 Singles' Day shopping festival, Cainiao's Guangzhou Zengcheng Cat Super Warehouse deployed 135 ZeeBot climbing robots to handle order peaks. Over a 28-hour period, the robot fleet accumulated more than 140 kilometers of vertical travel distance, achieving an on-time dispatch rate of 99.99% for multiple wave cycles. The warehouse utilizes a hybrid system where robots retrieve long-tail SKUs from high-density shelves to human workstations, while humans handle fine-grained picking and exception handling. The ZeeBot robots achieve a vertical climbing speed of 1.2 meters per second without requiring dedicated side rails, enabling flexible expansion of storage capacity.
