Natural guidance is an advanced AGV navigation method that uses the laser measurement sensor to scan and identify the surface of surrounding natural environments such as walls, columns and other landmark objects, thereby establishing the surrounding environment into the navigation map system. . During the actual walking process, the sensor measures the distance and the environment by continuously rotating the laser in the field of view. The AGV compares the static shape of the object scanned by the laser measuring sensor with the navigation map in the vehicle to control the vehicle's travel. Depending on the navigation device selected, the natural guidance maximum detection distance can reach 100 meters, which can meet the application of almost all scenes. The navigation stop accuracy is comparable to the laser guided AGV.
At present, the main guiding methods of domestic AGV applications are laser guidance, tape guidance or magnetic guidance, coordinate guidance, inertial guidance and the like. In the field implementation process, the laser guide needs to install the reflector according to the surrounding environment. The tape guide or the magnetic guide needs to lay the magnetic tape and the magnetic nail on the AGV travel path. These tasks are all to make the AGV have a good navigation environment to ensure the normal operation of the AGV, and these jobs occupy most of the time and workload. The natural guidance AGV does not need to rely on the installation of other auxiliary navigation objects in the field implementation process. It only needs to let the AGV automatically travel along the planned route for one week in the existing environment to establish the surrounding environment in the vehicle map. It can be seen that in the efficiency first, the natural guidance AGV makes the implementation of the site easier, greatly reducing the installation time and cost.
