AGV is a mobile robot, which integrates many functions such as environment perception, dynamic decision-making and planning, behavior control and execution.
AGV (Automated Guided Vehicles) is also known as unmanned vehicle, automatic navigation vehicle and laser navigation vehicle. Its main characteristics are unmanned, AGV equipped with automatic navigation system, which can ensure that the system can drive automatically without manual driving, and can carry goods or materials from the starting point to the destination automatically. Another characteristic of autonomous mobile car is its flexibility, high level of automation and intelligence. The moving path of autonomous mobile car can meet the requirements of warehouse goods. The cost of production process, such as changing and flexible changing the running path, is much lower than that of traditional conveyor belt and transmission line. AGV is equipped with loading and unloading machinery, which can automatically interface with other logistics equipment to realize the automation of the whole process of cargo handling. In addition, AGV has the characteristics of clean production. AGV relies on built-in batteries for power supply, no noise, no pollution in the operation process, and can be used in many harsh working environments.
Types of an AGV carrier
AGV has a history of 50 years since its invention. With the expansion of its application field, its types and forms have become diverse. AGV is often divided into the following types according to the navigation mode in the course of AGV auto-driving:
1. Electromagnetic Induction Guided AGV
Electromagnetic induction guidance is usually on the ground, driving along a predetermined road embedded wire, high-frequency current through the wire, the electromagnetic field in the conductor, autonomous mobile car symmetrically installed left and right two electromagnetic sensors, they receive electromagnetic signal intensity differences can reflect the degree of AGV deviation from the path. The automatic control system of AGV controls the steering of vehicle according to the deviation, and the continuous dynamic closed-loop control can ensure the stable automatic tracking of AGV's setting path. This inductive guidance navigation method is currently used in most commercial agv, especially for large and medium-sized agv.
2. Laser-guided AGV
The autonomous mobile car is installed in a rotating laser scanner. The reflective laser positioning mark is installed on the wall along the path or pillar. The autonomous mobile car depends on the laser. The laser scanner and the received positioning mark the laser beam reflecting back. The vehicle computer calculates the current position and direction movement of the vehicle. By comparing and building-in digital map orientation, the automatic processing is realized.
At present, the application of AGV is more and more popular. On the basis of the same guiding principle, if the laser scanner replaces the infrared transmitter or the ultrasonic transmitter, it will be advantageous for AGV to become the infrared laser heuristic AGV and the ultrasonic heuristic AGV.
3. Vision-guided AGV
AGV is a rapidly developing and mature AGV. AGV is equipped with CCD camera and sensor, and the environment image database is built on the airborne computer. In the process of AGV, the camera dynamically acquires the information of the surrounding environment and compares it with the image database to determine the next position and decision.
AGV is theoretically the best guide because it does not need any physical path settings. With the rapid development of computer image acquisition, storage and processing technology, AGV is stronger and stronger.
In addition, there are inertia-guided AGV and optical-guided AGV of ferromagnetic gyroscope.
