Mixed scheduling of multiple types and sizes of vehicles, 7mm process accuracy, Guozi AMR helps Xiaomi Auto Super Factory to start operation

On March 28, the eye-catching Xiaomi Motors was officially launched, setting a record of 50,000 orders in 27 minutes. In the Xiaomi Motors Super Factory in Tongzhou, Beijing, 94 AMRs provided by Guozi are busy working. The intelligent logistics solution provided by Guozi for Xiaomi realizes the mixed dispatch of vehicles of multiple models and sizes, meets the 7mm process accuracy requirements, and provides logistics support for intelligent automotive manufacturing.

7mm process accuracy

AMR automatically checks nearly 200 storage locations

Guozi AMR automatically aligns nearly 200 warehouses in the body shop and die-casting shop , and each warehouse has high-precision docking requirements. Guozi AMR adopts contour + SLAM high-precision navigation. The on-board navigation has the functions of inbound accuracy control and outbound accuracy maintenance, and corrects the navigation deviation of the inbound and outbound process in real time to ensure the accuracy and safety of the docking process.

At the docking point between AMR and robot arm , photoelectric detection and grating are installed at each point to ensure process safety. It is required that the margin between the rack and the storage position cannot exceed the safety range during docking, otherwise the grating reset and alarm will be triggered, resulting in process shutdown. The process accuracy of Guozi AMR reaches 7mm , which can achieve precise docking with the robot arm and rack in and out of the warehouse, and there is no manual participation in the whole docking process.

Multiple vehicles mixed traffic, intelligent dispatching

Storage location management, accurate loading and unloading

In the body shop and die-casting shop, the four AMRs of Guozi, A10, A15, 2T heavy-duty handling, and P4-X, automatically complete dozens of different carrier docking and handling tasks , including extra-long and extra-wide heavy materials, covering business scenarios such as logistics sorting areas, line-side buffer areas, and line-side production areas. Guozi uses a multi-layer, multi-carrier, and multi-model map for intelligent path planning and intelligent traffic management to achieve multi-vehicle mixed traffic ; through a global scheduling algorithm, it completes the optimal matching and planning of nearly 100 AMRs and over 100 tasks in the shortest time to ensure scheduling efficiency and accuracy.

P4-X adopts QR code + SLAM hybrid navigation mode, dynamic adjustment of forks, and flexible compatibility with a variety of different sizes of boxes ; using the white box in the temporary storage shelf area + black box in the line-side docking area intelligent docking mode, the Xiaomi management system WCS sends point-to-area and area-to-point tasks to exchange empty and full boxes. P4-X comes with deep camera recognition technology, which can identify the location status of the warehouse in real time, and cooperates with the two docking forms of multi-layer low-level shelves at the production line + multi-layer low-level flow racks to complete precise loading and unloading.

A15 in the die-casting workshop It is handling high-temperature materials that have just completed high-temperature die-casting and are at a temperature of nearly 100°C, fully demonstrating its good high-temperature resistance.

In view of the small space and small number of on-site warehouses, Guozi's intelligent warehouse management RCS system is connected with the Xiaomi management system WCS to intelligently manage the loading and unloading material cache warehouses, realize the intelligent flow of warehouses and waiting locations, and exchange empty and full material trucks without preparing empty warehouses , further improving logistics efficiency.
