Robots traversing 9-meter high shelves run over 3.3 marathons in a single large warehouse during peak season

This observer report details the deployment of ZeeBot climbing robots at Cainiao's Guangzhou 'Cat Supermarket' warehouse during the 2026 Double 11 shopping festival. The facility utilizes a hybrid system combining automated vertical storage with traditional manual picking to handle approximately 60,000 SKUs. During the peak period, 135 ZeeBot units operated within a 9-meter high rack system, covering over 140 kilometers of vertical distance in 28 hours while maintaining a 99.99% on-time dispatch rate. The article highlights the robots' ability to navigate without dedicated tracks, their integration with human workers for final picking and packing, and the use of AI-driven scheduling algorithms to manage traffic and task allocation in real-time.
