Natural navigation robots for manufacturing: the wind blows on the road

in recent years, a large amount of capital has poured into the field of AGV, prompting the rapid growth of the number of AGV manufacturers. In recent years, a large amount of capital has poured into the field of AGV, prompting the rapid growth of the number of AGV manufacturers

according to the data, the number of AGV enterprises in the Chinese market increased from 110 in 2015 to more than 600 in 2018, with a compound annual growth rate of 76%. In 2018, the sales volume of AGV in China reached 23500 units, with a year-on-year increase of 49.65%

Chen, co-founder and COO of Gezhi technology, first analyzed that the traditional magnetic stripe AGV has been used in China for many years and has received attention from automotive and other industries. The first upsurge of the new generation of AGV is led by Kiva like QR code navigation AGV. China's rich e-commerce and express delivery scenarios with an accuracy of 0.01 mm give storage AGV huge application space. However, after a period of time, people found that the input-output ratio of two-dimensional code navigation AGV in practical application failed to meet expectations, so the application growth of this kind of AGV gradually slowed down

with the continuous acceleration and deepening of the planning of digital and intelligent chemical plants, the demand for factory customization is becoming increasingly obvious, which requires that the automatic production line and logistics handling system of the factory must be highly flexible. AGV based on laser trackless navigation technology has become a trend

while a number of excellent enterprises entered the board, it also led to a situation of uneven industry and mixed ups and downs. Thanks to the continuous progress of machine vision, sensors, big data and other technologies, Chen first pointed out that as a device for end-users in the manufacturing industry, AGV is not only technology and products, but also applications and services. Customers ultimately pay for helping themselves solve real problems

gazhi technology, founded in 2016, found that for mobile robots, intelligent manufacturing is the most mature market that can be quickly launched and has a clear profit model. Therefore, since its inception, gazhi technology has been positioned to develop natural navigation mobile robots for manufacturing

the layout of the whole product line fills the gap in the industry

at present, gazhi products have covered the whole series of Emma industrial grade autonomous handling AGVs, intelligent unmanned forklifts, multi robot scheduling and management systems, outdoor medium and low-speed driverless vehicles, autonomous positioning and navigation modules, etc

Chen first said that the source of confidence for the layout of the whole product line is that Gezhi technology has inherited the accumulation of robot intelligent perception and motion control in the robot laboratory of the school of control, Zhejiang University for 18 years. In terms of the core technology of autonomous navigation, it has a full stack of robot technology, including positioning perception, navigation and obstacle avoidance, machine vision, etc

secondly, Gezhi technology not only provides a single robot product, but also a complete set of solutions for mobile robot + scheduling system, which also determines the overall product layout of Gezhi from single product to system

he stressed that real-time graphics can be switched dynamically during the test. The demand for robots in various industries in the manufacturing industry is different, and it is difficult to cover a large number of non-standard applications through several standard products. For b-end users, purchasing products is only part of the actual need is the overall system solution, more emphasis on localization services and customization capabilities

based on the development in recent three years, the load of Gazprom products has covered 200kg-2t, including indoor and outdoor environments

Chen first pointed out that for indoor robots, regardless of the load, there is little difference in the algorithm difficulty in software scheduling and navigation, but the research and development difficulty in electromechanical aspects is completely different. For example, for robots with a load of 1 ton or more, most innovative AGV companies are less involved, because soft technologies such as algorithms are relatively easy to use, but involving hardware, especially complex and high load electromechanical systems, it requires long-term accumulation

generally speaking, the application scenario of AGV with a load higher than 1 ton is special, and the goods handled are relatively special. Therefore, for AGVs with a load of more than 1 ton, it is often necessary to customize the models according to the cargo conditions of customers

in addition, goods of more than 1 ton are generally larger in size. In the limited channels of the factory, AGV will be required to have good flexibility and docking accuracy while handling large-scale goods. By turning the handwheel, the flexibility of the AGV in the traditional two wheel differential mode will be insufficient

therefore, gazhi technology has developed a series of technologies based on omni-directional mobile chassis, and improved the safety and reliability of AGV from hardware to software, so as to realize the flexible handling and high-precision docking of large tonnage and large-size goods in the narrow channel of the factory

at the same time, gazhi team has rich accumulation in the electromechanical and structural design of robots, including the chassis structure of various models, such as two wheel differential, four wheel differential, Ackerman chassis, steering wheel omni-directional mobile chassis, mcnamu wheel omni-directional mobile chassis. This is also the basis for gazhi technology to challenge heavy-duty AGVs and AGVs with different chassis

in addition, gazhi emma500-st, which has won the 2018 AGV crystal ball award for high-tech robot, has filled the industry gap of laser navigation (without reflector) for the flexible transfer vehicle of materials in the vertical warehouse and platform at home and abroad

emma500-st is developed according to the characteristics of the vertical warehouse in combination with the transportation needs between the vertical warehouse and the line warehouse on the production line. Chen first analyzed the difficulties. When the AGV enters the silo, the gap between the AGV and the silo platform is only 2~3 cm, which requires that the absolute positioning accuracy of the robot in the process of entering the silo platform should reach 1 cm, or even less than 5 mm, and the accuracy of the whole running path should be kept within 5 mm

on the other hand, in the application of the library, AGV is facing a very open environment. In a case of a listed company customer in gazhi, it is necessary to use nearly 30 sets of emma500-st in a 50000 square meter plant

laser slam relies on obstacles for identification or guidance according to the surrounding environment. However, in this visible range, the markers are very rare, or the markers are more than 20 meters away. In addition, in a wide environment, the laser is easy to shake due to the uneven ground, which brings great challenges to positioning and navigation. Chen first further pointed out

according to this practical application condition, through the improvement of algorithm, the emma500-st is not vulnerable to environmental changes, and can accurately navigate according to path planning and multi-sensor

for outdoor robots, the difficulty lies in: on the one hand, the chassis structure applicable to outdoor robots is relatively special. The traditional two wheel differential structure is not completely suitable for outdoor uneven roads, but prefers to use Ackerman structure chassis similar to cars, which is more difficult for electromechanical design and control; On the other hand, the outdoor environment is more complex than the indoor environment, and the traditional two-dimensional laser navigation algorithm can not meet the application of outdoor unstructured scenes

gazhi technology is the first robot team in China to launch a semi enclosed park with an area of 500000 square meters and above that can realize unmanned distribution only by 3D laser slam. Relying on the three-dimensional slam technology, gazhi outdoor robot can meet the application of various outdoor large scenes

nowadays, in addition to laser radar, the core components of gazhi robot, including core controller, servo driver, visual sensor and electronic control system, are independently developed, which has obvious advantages in cost

create a multi industry smart manufacturing logistics model

at present, Jiazhi has accumulated a wealth of application cases, including the famous listed enterprise intelligent power distribution equipment green digital intelligent factory project, the world's largest ODM professional OEM material handling project, the domestic electronic manufacturing enterprise fast line change lean production project, the foreign famous printer production enterprise ink box workshop automatic material distribution project, etc

different industries have different special difficulties. Chen first gives an example. The automatic chemical plant in the power distribution industry belongs to a single plant with a large area and open space. How to realize high-precision, high reliability and high robustness positioning and navigation under the condition of large-scale map and very few references is a very difficult point

in 3C industry, the environment we face is that there are many forms of docking machines, and the scheduling system is complex. Therefore, how to meet the high-precision docking requirements of different equipment through the customization of vehicles in electromechanical aspects is a difficulty. In addition, the site of 3C factory is generally narrow, and the requirements for navigation accuracy and control ability are high. In addition, in the semiconductor industry, the difficulty lies in the particularly high requirements for dust-free

according to the characteristics of different industries, Gezhi technology will not only carry out targeted research and development of AGV products, such as designing a 600mm wide body, which can smoothly pass through the 800mm wide channel of AGV; It will also combine the mobile ability with the equipment docking ability to launch special AGV equipment for sub industries. For example, it will design a special aircraft similar to the packaging for semiconductor IGBT industry and suitable for applications in the semiconductor industry in combination with the vehicle it carries

the overall intelligent logistics solution of gazhi technology, with gazhi AGV robot as the core and relying on the intelligent scheduling system cloudia, not only realizes the flexible and efficient transportation of internal materials, but also pays more attention to the seamless connection with the WMS, ERP and MES systems of the enterprise, starting from the data exchange and connection of all links, helping enterprise managers better improve production processes, lean production and optimize resource allocation

at the same time, through cloudia, users can also view the location information, operation status, task execution and other conditions of each AGV at any time, timely understand and collect relevant logistics data, and realize the traceability and recordability of the whole process of material operation when necessary

in addition to 3C electronics, auto parts, power distribution, medicine, semiconductors and other industries with relatively mature application of AGV at present, gazhi technology will also explore new photovoltaic energy, 5g communication and other fields in the future

welcome 5g tuyere

at present, the total number of gazhi is about 65, of which R & D personnel account for more than 50%. Chen first revealed that the new strategy of gazhi in 2019 is to expand new industries on the basis of existing products, and then measure the size and size of the application of output, and develop more AGV overall solutions and models suitable for various industries; At the same time, the application field of AGV is gradually spread out in the industries that have been cut in

undoubtedly, 5g is the hottest concept in 2019. For the arrival of 5g, gazhi naturally does not want to be absent. Gazhi's products, including robot scheduling system and job management system, are developed based on a 5g compatible architecture. At present, based on the limitations of communication, privatized deployment schemes are adopted. With the improvement of 5g infrastructure, these schemes will be transferred to the public cloud or private cloud

gazhi has also made corresponding technical reserves for 5g to change the communication mode between robot multi machine scheduling and servers. Chen first said: 5g technology will bring an imaginative revolution for robot communication, scheduling and information processing
