[Classification by guiding method]

1. MGV (Magnetic Guide Vehicle)

- Buries magnets or affixes magnet tape on the floor to guide using a magnetic guide sensor.

- Buries spots (iron plates, magnets) in the floor at certain intervals to guide/control AGV positions using a guide sensor.

- Easy to install and operate and has low construction costs.

2. Optical Guidance

- Guides AGV with a PGV sensor by attaching colored tape or QR code to the floor.

- High-precision and easy to control traffic.

3. LGV (Laser Guide Vehicle)

- Guides with a laser scanner using AGV's absolute coordinates after installing a high-brightness reflector.

- Enables high-precision driving.

- Track can be changed and expanded wherever an LGV-recognized reflector is attached.

4. SLAM (Simultaneous Localization and Mapping)

- Guides driving by recognizing images of terrain using surrounding terrain, installing random terrain, or laser distance.

- Easy to create a new map even with frequent changes in the location of facilities.

[Classification by driving method]

1. SD (Single Driver) Type

- General AGV driving method.

- Driving and steering motors are assembled in one configuration (dedicated AGV wheels).

- Guiding baseline is located at the center of the driving part, and the control moves along the baseline.

2. DD (Dual Driver) Type

- Steering control uses the speed difference between two motors.

- Easy to spin/turn and move backward.

- Has a stable structure for handling high-load cargo.

- High steering control skill is required with the implementation of the speed deviation-based steering, which is a typical AGV driving method.

3. QD (Quad Driver) Type

- Drives individually by arranging the SE-type motors front and back (left, right).

- AGV can transfer and load cargo immediately after making a sharp curve.

- Zigzag driving is possible.

- Stable when loading up to 6,000 kg.

- Dual driving requires high-control skills.
