, as its name implies, is an AGV car
that works outdoors. Compared with indoor AGVs,
the relatively harsh outdoor environment has higher technical requirements for outdoor AGVs, and there are relatively few application scenarios. Except for the distribution robots that have not yet been fully applied, there are three main scenarios for outdoor AGVs. One is the distribution of materials between different plants in the park, the other is the loading and unloading of ports and terminals, and the third is the outdoor inspection of the power industry.
Park distribution-preliminary exploration
In some large manufacturing industries, the manufacturing process is not limited to a single plant. Therefore, the distribution of materials is not only inside the plant, but also involves the logistics between the plant and the factory room. In this scenario, it is necessary to use To outdoor AGV.
In the automotive industry, exploration of outdoor connection AGV has begun. The automotive industry is the industry with the longest history of AGV applications, and it is also very familiar with the process and application characteristics of AGV. For example, Dongfeng Nissan's four major production bases in China (Guangzhou Huadu, Xiangyang, Zhengzhou, Dalian) used more than 1,000 sets of AGVs. Based on its rich application foundation, Dongfeng Fengshen has developed an unmanned tractor suitable for internal road operation for logistics distribution between factories.
There are also many companies in the industry that have successively launched outdoor AGV products, with a few application cases.
For example, an outdoor traction AGV developed by Anhui Yufeng has been successfully used in outdoor transportation operations in prisons. This AGV uses GPS global positioning system + multi-line lidar auxiliary positioning system, which can realize unmanned transportation and unmanned traction. A variety of application functions, can also operate normally in extreme weather such as thunderstorm, high temperature and severe cold.

Through the measurement laser and inertial navigation technology, reliable navigation in non-standard environment is achieved, which greatly expands the applicable environment of AGV and can realize outdoor all-weather and high-frequency operation, which has received good feedback from users.

In addition, some manufacturers in the industry have also started the research and development of outdoor AGVs in the park. For example, an outdoor delivery robot has recently been launched, mainly for JD.com, but overall, the outdoor delivery of the park is currently in preliminary exploration. The application is not very mature and needs to be verified.
Ports and docks-mainly heavy-duty AGV
The port terminal is a major focus area for outdoor AGV applications. Its application can be traced back to 1993. At that time, the world's first container automated terminal was put into production at the ECT Delta Sealand in the port of Rotterdam. Among them, the horizontal transportation of containers uses AGV to fix The route runs. Since then, with the continuous development of technology, the application of port AGVs has gradually increased.
However, the port automation intelligent terminal not only needs AGV to operate normally in the harsh environment, but also needs to meet the needs of handling dozens of tons of containers, so the heavy-duty AGV has become the protagonist of the port terminal. Compared with ordinary AGV, the heavy-duty AGV technology used in ports and terminals is more demanding. At present, there are more than ten domestic heavy-duty AGV manufacturers, which are mainly established AGV companies and large-scale machinery equipment manufacturers, but there are not many cases of port and terminal applications in these companies.
This is because the port and dock industry has a very strict choice of equipment, and it is very difficult for general enterprises to enter. For example, in the Yangshan Port Phase IV terminal, which was completed the previous year, the automation equipment used was provided by Zhenhua Heavy Industry, including multiple heavy-duty AGVs. Compared with this large-scale mechanical equipment manufacturer, whether it is Capabilities are still overall project planning capabilities, and ordinary AGV vendors have a certain gap with them. Therefore, the current port terminal market is basically monopolized by large machinery and equipment manufacturers.
Of course, AGV manufacturers with both integration and equipment capabilities are not absent, such as Xinsong's outdoor trackless navigation heavy-duty mobile robots have successfully settled in Singapore's Port of Glass this year. But in general, for general AGV manufacturers, the port and port market is still quite difficult to enter.

It is worth mentioning that the current AGV applications at ports and terminals are mostly magnetic navigation, because the technology is more mature and stable. The Yangshan Phase IV AGV senses itself through 61483 magnetic nails buried underground. Location to follow the optimal route based on real-time traffic conditions.
Outdoor inspection-focus on the power industry
Outdoor inspection is also an application that has only begun to be promoted in recent years. At present, it is mainly concentrated in the power industry, and is generally used in transformer substations and converter stations. The intelligent inspection AGV system is mainly composed of a mobile vehicle body and a base station. The mobile vehicle body and the base station communicate through a 5.8G wireless spread-spectrum network. Mobile car body includes AGV car body, control system, obstacle detection system, navigation and positioning system, communication system, detection equipment, etc. The base station includes a wireless transmission system, a background control system, a data analysis and display system, and a database system. In terms of navigation, the early power inspection AGVs were mostly based on magnetic navigation. With the development of technology, the current number of trackless navigation has gradually increased.
