  • Detail

With the rapid development of industrial manufacturing technology, the degree of automation and intelligence of production plants in various industries is becoming higher and higher, and various types of industrial robots such as manipulator, cooperative robot and mobile robot have gradually become the standard configuration of intelligent factories. The robot arm replaces the manual to complete most of the production automation links, greatly improving the production efficiency and productivity, while the mobile robot realizes the automatic docking and circulation of logistics in all links, and truly realizes the unmanned production

for the traditional industrial manipulator, due to the fixed position of the fuselage and the limitation of the motion radius by the size of the arm span, the scope of operation is limited. Many companies began to try to match and assemble the manipulator and mobile robot to form a composite robot with more functions and capable of handling more links, in order to make the manipulator's operation location no longer limited and reach the places that could not be reached in the past, To meet the needs of flexible production of workshop automation equipment

hands and feet of composite robots

composite robots are new robots with two functions of hands and feet. In the past robot world, general-purpose industrial robots were called mechanical arms; The intelligent mobile robot is used to replace the function of human legs and feet to move and control the direction. Compound robot combines the advantages of the two, using both hands and feet to combine the two functions

however, the traditional industrial manipulator is not suitable for the hand as a composite robot because of its heavy body, heavy load on the autonomous mobile robot, too rigid arm extension, and insufficient security, so it came up with the idea of using a cooperative robot to replace the industrial manipulator as this hand

compared with traditional industrial robots, although the load of cooperative robots will be much smaller, they are cheap and easy to use. More importantly, they have strong adaptability, more flexibility and high safety. Compared with industrial robots that have been developed for decades, they can directly cooperate with production field workers to improve the degree of automation and work efficiency on the basis of ensuring safety. A large number of well-known cooperative robot brands at home and abroad, such as ur, Feixi, Aobo, alite, have also emerged

as the feet of composite robots, mobile robots are a very important part of composite robots. According to the navigation methods, there are mainly magnetic stripe navigation, two-dimensional code navigation, laser slam navigation and visual navigation. At present, the mobile robot guided by laser slam has become the main choice of most composite robots because of its stable navigation, strong adaptability to the environment, autonomous movement and many other advantages

the composite robot of the autonomous mobile robot based on laser slam navigation does not need any auxiliary marks, and does not need to transform the factory environment. It can avoid obstacles and detour independently when encountering people and goods. The flexible intelligent production is realized by the unified allocation of mobile robot scheduling system

application advantages of compound robot

what are the advantages of compound robot with hands and feet

first: improve the level of automation in the production process

composite robots are conducive to improving the automation of raw material and parts transmission, workpiece loading and unloading, and machine assembly, so as to improve labor production efficiency, reduce production costs, and accelerate the pace of mechanization and automation of industrial production

II: improve working conditions and avoid personal accidents

the composite robot can partially or completely replace people to safely complete the poor display in the workstation. It is found that the travel of the actuator is only 10mm, which should be 50mm under normal circumstances. It is considered that there is a problem with the system setting, and the system needs to be reset After resetting the travel of the actuator to 50mm, the displayed value on the display panel of the workstation is still incorrect, so it is considered that only by re calibrating and relocating the system can we solve the dangerous operation in this fault environment and greatly improve the working conditions of workers. At the same time, some simple but cumbersome handling work can be replaced by composite robots, which can avoid the loss caused by human operation fatigue or the end of the experiment

III: flexibility of production line

the compound robot can carry out the next process after completing one process, which has high flexibility. And multiple composite robots form a mobile assembly platform and processing platform, which can form a highly flexible production line

application fields of composite robots

at present, composite robots are more and more widely used in the assembly of components in 3C electronics, medical treatment, daily chemicals, machining and other manufacturing industries. Composite robots can be used for grasping, assembling, handling, loading and unloading of processing workpieces

in addition, the composite robot can also be quickly deployed in many scenes such as automatic chemical plants, warehousing and sorting, automated goods supermarkets, etc., providing automatic and flexible operation support for the automatic handling of materials, the loading and unloading of goods, and the sorting of materials, so that the logistics in the plant can realize real unmanned handling

whether industry 4.0 can become the spring of composite robots

with the continuous deepening of industry 4.0, industrial robots therefore transition from the third stage to the fourth stage to solve the problem of flexible production. Returning to the reality of China's manufacturing industry, the current development strategy is to strive to achieve overtaking in curves, and to promote automation, informatization and intelligence at the same time. In made in China 2025, it is clearly proposed to take intelligent manufacturing as the main line and speed up the integration of the two. In this context, it is not difficult to predict that the compound robot will have a great application space and development prospects

the biggest difference between the Tokyo robot exhibition in 2019 and the previous exhibition is that all major robot exhibitors show the display of composite robots in different scenes, which also seems to confirm the development trend of composite robots

in the future, more cooperative robot manufacturers and mobile robot manufacturers must cooperate more to jointly solve the problems of composite robot load is too small, unable to touch the ground, faster communication, product/industry standards and so on, and realize the productization, rapid development and large-scale application of composite robot faster

control + scheduling = Xianzhi robot

when it comes to laser slam composite robot, we have to mention Xianzhi robot with leading laser slam navigation technology

the composite robot based on Xianzhi AMB series unmanned handling chassis can be used in working conditions that require high flexibility for precise loading and unloading, with an accuracy of up to 5mm. Autonomous navigation, the mobile robot can accurately walk and stop at the designated place in the process of moving and parking, complete a series of flexible and precise loading and unloading operations, and open the agreement. At present, it has been adapted to the manipulator of many brands to meet the needs of different customers

the compound robot based on Xianzhi AMB has been successfully implemented in 3C electronics, certificate production, new retail and other industries, and has been widely recognized by integrators and end customers
