The principle of QR code navigation AGV (Automated Guided Vehicle) is to scan the QR code laid on the ground through the QR code sensor to obtain the current location information, thereby achieving navigation and positioning. Specifically, AGV scans the QR code laid on the ground through the camera and parses the QR code information to obtain the current location information. These QR codes are usually combined with inertial navigation to achieve precise positioning.
The workflow of QR code navigation AGV includes the following steps: First, the QR code sensor scans the QR code laid on the ground to obtain the location information; then, this information is passed to the AGV controller, and the controller calculates the coordinate data provided by the image sensor to determine the location of the AGV in the map; then, the scheduling system sends the navigation path instruction to the AGV car; finally, the AGV car drives to the destination according to the received path instruction.
The advantages of QR code navigation AGV include fast speed, high accuracy, free route planning, no need to lay magnetic strips, and space saving. In addition, it can also be connected to the warehouse management system to update the material status and the location of the landmark in real time. However, QR code navigation AGVs also have some disadvantages, such as the need for regular maintenance of the path, the need to frequently replace the QR code when the site is complex, and strict requirements on the accuracy and service life of the gyroscope.
