China's 200 robots automate entire excavator production process

Guozi Robotics, a Hangzhou-based Chinese company, has deployed nearly 200 diverse robots to fully automate the excavator production process at TZ Group’s new factory. Their intelligent system integrates mobile-robot swarms, gantry robots, cobots, and turnover units to perform complex, high-mix manufacturing operations without re-tooling delays. Equipped with intelligent navigation, flexible collaboration, and multi-agent dispatching, these robots streamline production from assembly through final shipment. The project operates on Guozi’s proprietary Line-Side Control System (LCS) and Manufacturing Execution System (MES), enabling seamless data integration between shop-floor devices and plant management. Guozi’s heavy-duty robot families, including ANTS and PICKING robots, have already been implemented in leading construction machinery factories worldwide, such as Zoomlion, XCMG, and Sany. Their AI-driven robotic control system (RCS) coordinates hundreds of automated guided vehicles (AGVs) with centimetre-level accuracy, supporting dynamic storage
