The navigation of traditional AGV (Automated Guided Vehicle) is mainly guided by magnetic stripe, magnetic nail, ribbon or QR code. Their common point is that they all use fixed path navigation, which has inherent defects of poor flexibility and flexibility, and high dependence on the environment. In the face of complex working scenarios, traditional AGV is difficult to meet customer’s needs.
However, in recent years, the laser navigation AGV based on SLAM (Simultaneous Localization And Mapping) technology has become increasing. It can adapt to complex, cumbersome and intelligent instruction requirements, effectively solve the problems of the first and second generation AGV products, and meet the needs of manufacturing enterprises. Laser navigation AGV has entered the third generation AGV era.
Four scenarios to meet the requirements of intelligent manufacturing
At present, the manufacturing industry is faced with problems such as increased cost and difficult recruitment, but some repetitive and tedious necessary work is an indispensable link in the manufacturing chain; At the same time, the transportation and management of materials also need to be strengthened for the operation links with strict requirements on the handling and flow of some valuable devices. Therefore, the enterprise managers have to improve the level of intelligent production.
"Laser navigation AGV is a robot mainly used for material handling, which is suitable for semiconductor, automobile manufacturing, 3C manufacturing and other industries."
The first is the handling in the warehouse, which is mainly used to solve the problem of material transportation and management in the warehouse. It is a scene widely used at present.
The second is the handling in the production line, which is used to complete the material handling and management in the production line.
The third is the transportation between the warehouse and the production line. Together with the transportation scene in the production line, it is currently the most widely used scene.
The above three scenarios are basically one-to-one material handling. The laser navigation AGV can detect the surrounding environment in real time through the laser radar. When encountering obstacles such as moving people, objects and forklifts, the laser navigation AGV will stop moving or wait for people and forklifts to move awa before continuing to move; If it is judged as an immovable obstacle, the laser navigation AGV will automatically find the path to bypass the obstacle to reach the destination. "Compared with the traditional way, the biggest advantage of laser navigation AGV is that it does not need to make any changes to the environment, has strong obstacle avoidance ability and good adaptability to complex environments.
The fourth scenario is the cross production line transportation, which is a many to many transportation method. It is also the most complex and difficult application among the four scenarios. Because there are few cross production lines, there is no conveyor belt between them for material transportation, and it may involve multiple demands, cross floors, and multiple materials being transported to multiple production lines in complex scenarios; The environment is no longer fixed, and people often walk around, vehicles keep flowing, and goods are stacked in disorder, which poses a great challenge to AGV application. Traditional AGV products obviously cannot meet the material transportation requirements in such complex scenarios.
A full set of solutions to meet the needs of intelligence.
At present, AGV products mainly solve the problem of material transportation, and the placing and taking of materials mainly depend on manual work. However, for some production lines with high requirements for intelligence, AGV has begun to be required to have the ability to place and take materials independently.
