AGV carts have those navigation methods?

The AGV has the following navigation methods:

1. Electromagnetic guidance

Electromagnetic guidance method is the earliest and most used one, it is buried in the ground under the ground groove in the wire, by the AC frequency generator input a low-voltage, low-frequency current, the AC electric signal along the wire around the generation of a magnetic field, the AGV is equipped with two induction coils, you can detect the strength of the magnetic field and expressed in the form of voltage.

2. Magnetic tape guidance

The principle of magnetic tape guidance and electromagnetic guidance is very similar, magnetic tape guidance with magnetic tape instead of electromagnetic guidance buried metal wire. Compared with the electromagnetic guidance, the flexibility is better, it is easier to change or expand the guidance path, but it is easier to be interfered by the surrounding metal objects than the electromagnetic guidance, so the AGV of this guidance method has higher requirements for the application environment.

3. Laser guidance

This guidance method is installed in the AGV driving path around the precise position of the laser reflector, AGV by transmitting laser beams, colleague collection by the reflector reflective laser beams, to determine its current position and direction, and through the successive triangular geometric algorithms to achieve the guidance of AGV. It is a bit of accurate positioning, and the ground without other positioning facilities, guidance path is flexible and adaptable to a variety of on-site environments, is currently many foreign manufacturers of AGV limited to the use of advanced guidance methods.

4. Visual guidance

Visual guidance has two methods, one is the use of cameras to collect real-time driving path around the environment of the image information, and has been established with the operating path around the environment of the image database for comparison of the information, to achieve the control of the AGV. The other is an image recognition method based on the guide line, using the camera to collect real-time images of the guide line and calculate the deviation between the guide line and the cart, so as to control the AGV to travel along the predefined and planned guide line.
