With the advent of the era of intelligent everything, in manufacturing workshops, especially in the field of heavy industry, heavy-duty AGVs have become the first choice for intelligent upgrades by many manufacturing companies.
Recently, the independently developed 50-ton heavy-duty AGV made by Weihua Group's Weite Robot Company made a surprise appearance and was delivered to customers, marking Weihua's move to a new level in the field of intelligent handling robots.
With its large size, high load capacity, leading technical advantages and intelligent features, Weihua heavy-duty AGV can complete the processing, manufacturing and transportation of large objects that other AGV vehicles cannot complete.
Advantages of heavy-duty AGV technology
1. Using laser SLAM and navigation algorithms
m Accurate positioning
Laser SLAM and navigation algorithms can improve positioning accuracy by 1cm from the industry's 5cm, greatly improving the accuracy and robustness of laser positioning.
The so-called robustness is the ability of the system to maintain certain performance unchanged under the disturbance of uncertainty.
2. Overloaded AGV dispatching system
m overall optimal solution
The overloaded AGV scheduling system is equivalent to the brain of the AGV. It does not pursue the optimal solution for a certain action, but the overall optimal solution.
The project R&D team completed Weihua's first self-developed AGV dispatching system, which allows AGVs to complete docking with external systems, complete more actions, and realize more functions.
3. Multi-wheel motion control technology
m Stable performance and strong driving force
The heavy-duty AGV drive system has extremely high requirements for smoothness, flexibility and durability. The complexity of motion control increases exponentially as the number of wheels increases.
This project adopts the control of 16 wheel sets. Ultra-low omnidirectional dual differential drive assemblies are used between the multiple wheel sets to compensate for the unevenness of the ground. This enables multiple sets of wheel systems to be in contact with the ground, and the load-bearing and driving capabilities are greatly enhanced, which not only ensures safetyIt is stable and can achieve high power output.
4. 3D visual suspended obstacle detection
m Reliable, safe and accurate
It adopts an industrial-grade 3D depth vision camera, which can be used for precise positioning and accurate identification. It can not only detect objects in front of the robot, but also detect obstacles in the upper space. This not only avoids collision damage to materials during driving, but also provides a line of safety for people coming and going on site, providing customers with a safe and reliable handling experience.
5. Contactless charging
m Green, economical and convenient
Powering the AGV through induction does not require the use of cables to connect the AGV to the power supply system, avoiding unfavorable factors such as contact wear, arc sparks and high AGV positioning requirements.
Contactless charging does not require expensive electric actuators, which greatly reduces equipment costs and labor costs. It has the advantages and characteristics of high reliability, no need for maintenance, not afraid of dust pollution, and can work normally in humid environment.
Weihua Intelligent Handling System
Under the guidance of the "Made in China 2025" policy, Weihua seizes strategic development opportunities and leverages its advantages as an industry leader. By establishing a digital factory to upgrade logistics handling equipment and a smart logistics dispatching and command platform, it promotes the deep integration of industrial AGVs, machine vision, lifting logistics equipment and 5G networks, and builds a trinity of high-altitude, low-altitude, and ground material handling application scenarios in the factory.
m Upgrade material handling equipment
Weihua connects core material handling equipment in the factory, such as high-altitude logistics handling equipment (cranes), low-altitude material dumping equipment (stackers), and automatic navigation vehicles (AGV), to the 5G network, upgrades the control and data transmission systems of the equipment, and creates 5G+ intelligent logistics equipment.
m Establish a smart logistics dispatching and command platform
Through 5G+ intelligent material handling equipment, we can realize millisecond-level delayed industrial control signals and high-definition camera video data, realize remote control of AGVs, high-definition video backhaul of cranes, and three-dimensional warehouse stackers. Combined with business information systems such as WMS, ERP, MES, and SRM, we can realize the automation and intelligence of the entire process of logistics terminal control, parts storage, transportation, and sorting, and realize the intelligent upgrade of smart factory logistics and transportation.
Facing the future, Weihua will closely follow the wave of "Made in China 2025", deeply cultivate the green, intelligent, customized and digital development of lifting equipment, continue to make efforts in intelligent production, intelligent products, and intelligent services. Based on "equipment data + AI algorithm", we will optimize and improve the efficiency of supply and demand docking in the lifting industry, promote the "supply-side reform" of the lifting industry, and contribute Weihua's strength to the rapid development of China's intelligent handling industry.
