Inertial two-dimensional code navigation AGV for industrial AGV logistics

Inertial two-dimensional code navigation is also called magnetic nail navigation. Later, there is also a name called machine vision. The core of positioning and navigation stability is still the inertial navigation method through the gyroscope.

The inertial navigation AGV has a low threshold for its positioning technology and motion control technology. The navigation system consists of a single chip microcomputer, a gyroscope, and an accelerometer. The performance is determined by the sensor noise, the calibration beacon (two-dimensional code or other), and the gyro chip itself has cumulative error, and the error will increase with time. Inertial QR code navigation is absolutely hard, and it is not very suitable for some production lines that require high precision. For the tens of thousands of repeated operations in the factory room every day, although the inertial navigation sensor can reset the data, so that the accurate short-term position, speed, acceleration, attitude, and angular rate can be output, but the error will be accumulated after a long time, and the number of manual resets will be compared. More, there is also the need to maintain a constant replacement of the QR code on a regular basis, which is more troublesome.
