The threshold of two-dimensional code positioning and navigation technology and motion control technology is not high. The working principle of two-dimensional code AGV navigation car is that two-dimensional code AGV navigation obtains the position in the two-dimensional code image coordinate system laid on the ground by controlling the scanning of two-dimensional code sensor; the collected two-dimensional code image coordinate position information is transmitted to the AGV controller, and the controller calculates the number of coordinates provided by the image sensorAccording to the data, the position of the image in the map is determined; the scheduling system sends the AGV car navigation path instruction; the AGV car establishes the local navigation coordinate system and calculates the initial position of the AGV car according to the received path instruction; the AGV controller controls the number of turns of the two wheels through the encoder information feedback, so that the AGV car travels to each two-dimensional part of the navigation path instruction sequence in turnCode image tag to complete the navigation path instruction.
Advantages of two-dimensional code navigation AGV:
Accurate positioning, small and flexible, easy to lay and change the path, easy to control communication, no need to worry about acousto-optic interference.
Disadvantages of two-dimensional code inertial navigation AGV car:
1. Due to the characteristics of the gyroscope chip itself, along with the increase of time, the greater the error accumulation, which is also the absolute hardness of inertial two-dimensional code navigation, is not very suitable for some production lines that need high-precision operation.(QR code inertial navigation sensor can reset data)
2. The QR code of AGV is easy to be damaged, so it needs regular maintenance and replacement;
3. If the site is complex, users need to change the QR code frequently
