Industrial robot is a mechanical, electronic, control, computers, sensors, artificial intelligence and other advanced technology subjects in one of the important modern manufacturing automation equipment. Since 1962, the United States developed the world's first industrial robot since, robot technology and products developed rapidly, it has become a flexible manufacturing system (FMS), factory automation (FA), computer integrated manufacturing system (CIMS) automated tools.
Widely used in industrial robots, not only can improve the quality and yield of the product, but also to protect the personal safety significance, to improve the working environment, reduce labor intensity and improve labor productivity and save raw material consumption and lower production costs, it has a very important. And computer network technology, widely used in industrial robots are increasingly changing people's production and life.
First, the industrial robot technology status and development trend of domestic and foreign
Industrial robots are the most typical mechatronic digital equipment, high value-added technology, wide range of applications, as technical support and information society emerging industries of advanced manufacturing, production and social development in the future will play an increasingly important role. Foreign experts predict that the robotics industry is a new large-scale high-tech industries after automotive, computer following appears. According to the Federation and the United Nations Economic Commission for Europe (UNECE) Robotics (IFR) statistics, the world robot market prospects, starting from the second half of the 20th century, the world's robotics industry has maintained a good momentum of steady growth. Into the 1990s, robotic product development speed, average annual growth of about 10%. 2004 annual growth rate reached a record 20%. Among them, the most prominent Asian robot increase up to 43%, as shown in Figure 1.
Status and Trends of Development of Industrial Robots

In recent years, the field of robotics development abroad has the following trends:
1. Industrial robot continuously improve performance (speed, high precision, highly *, ease of operation and maintenance), and the stand-alone prices declining average unit price from $ 103,000 down to 91 years 97 years 65 000 dollars.
2. Mechanical structure to a modular, reconfigurable development. Such as joint module servo motor, reducer, testing the system Trinity; by the joint module, link module constructed recombinant robot machine; modular assembly robot products abroad has asked the city.
3. Industrial robot control system based on an open controller to the direction of the PC development, facilitate standardization, network; device to improve integration, control cabinet has become increasingly compact and modular structure; greatly enhanced the system can be *, easy to operate and serviceability.
4. Robot sensors increasingly important role, in addition to the traditional position, velocity and acceleration sensors, assembly, welding robots use visual, haptic and other sensors, and remote control robot is using visual, sound sleep, haptic, tactile multi-sensor fusion technology for environmental modeling and decision control; multi-sensor fusion technology has been mature application configuration in the product of the system.
5. The role of virtual reality technology in the robot from the simulation, the development of rehearsal for process control, such as the remote control robot operator to generate exposure to the distal end of the operating environment in the sense to manipulate the robot.
China's industrial robot from the 80's "Plan" science and technology research started in support of the state, through the "July", "August" science and technology research, has mastered the robot manipulator design and manufacturing technology, control systems hardware and software design, kinematics and trajectory planning techniques, the production of key components of the robot, developed a painting, welding, spot welding, assembly, handling and other robot; which has more than 130 sets of painting robots in more than twenty enterprise nearly 30 automatic painting line (station) on the application of scale, arc welding robot has been applied in automobile factory welding line. But there is a certain level of distance and abroad than the whole, China's industrial robot technology and engineering applications, such as: * can be lower than foreign products; robot application engineering started late, narrow applications, the production line technology systems compared with foreign countries there are gaps; in the application of the scale, China has installed about 200 sets of domestic industrial robots, about the number of units installed worldwide in four ten thousandths. The main reason is not formed above the robotics industry, China's current production of robots is the user's request, "one customer, a re-design" of different specifications, small volume, low degree of component commonality, long lead times, costs not low, and quality, * unstable. There is an urgent need to address the early industrialization of key technologies, the product of a comprehensive plan, improve serialization, universal, mold design, and actively promote the industrialization process.
Second, the application of increasingly wide range of industrial robots
After forty years of development, industrial robots have been an increasing number of fields has been applied. In manufacturing, especially in the automotive industry, industrial robots have been widely used. As in the blank manufacturing (stamping, casting, forging, etc.), machining, welding, heat treatment, surface coating, loading and unloading, assembly, testing and storage and retrieval and other operations, robots have gradually replaced the manual operation.
With the improvement of industrial robots to deeper and broader direction of development and the level of intelligence of the robot, the robot's range of applications is constantly expanding periphery, from the automotive industry extended to other manufacturing industries, such as mining robot and then extended to the construction industry robot and hydropower systems maintenance and repair robots and other non-manufacturing industries. In addition, the application of national defense in the field of robotics, health care, life services, more and more, such as unmanned reconnaissance aircraft (aircraft), guard robots, medical robots, domestic service robots are application examples. The robot is to improve the quality of human life plays an important role.
Third, the major domestic and foreign manufacturers of industrial robots
In other countries, industrial robot technology has matured, has become a widely used standard equipment industry. Thus, have formed a group of influential, well-known industrial robot company, including: Sweden abb Robotics, Japan fanuc, Yaskawa, Germany kuka Roboter, United States Adept Technology, American Robot, Emerson Industrial Automation, ST Robotics, Italy comau, British AutoTech Robotics, Canada Jcd Robotics, Israel Robogroup Tek companies, which has become its pillar industry in the region. In China, the industrial robot industry has just started, but the growth momentum is very strong. New pine robot companies such as Shenyang Institute of Automation Chinese Academy of Sciences set up investment, annual profit growth of around 40%.
Fourth, the development trend of industrial robots
The use of industrial robots in many areas of production practice proved that it is the level of automation to improve production, improve labor productivity and product quality and economic efficiency, improve labor conditions, has a role in attracting world attention, causing the world's countries and all levels of society a wide range of interested parties. In the new century, the robotics industry will be more rapid development and more widely used.
1, the development trend of industrial robot technology
In recent years, the world's robots introduced products, the industrial robot technology is the intelligent, modular and systematic direction, its main trends are: modular and reconfigurable structure; and a control technique of open , PC and network; digital servo drive technology and decentralization; multi-sensor fusion technology practical; workplace design optimization and operations as well as flexible and intelligent network system and other aspects.
2, the development trend of industrial robot industry
According to UNECE / IFR predicted that by 2007, the global number of newly installed robot installed from 2003 to 81800 units increased to 106,000 units in 2007, an average annual growth of 7%. Among them, Japan 2003-- industrial robot sales in 2007 grew from 31,600 in 2003 to 41,000 units in 2007; Europe 2003-- 2007 Industrial Robots from 27100 units in 2007 to grow to 34,000 units in 2003; North American 2003- industrial robot market in 2007 the average annual growth of 5.8%, to 2007 will grow to 16,000.
Discussion V. industrial robot industry development model
Throughout the countries in the world in the development of industrial robotics industry processes can be grouped into three different models of development, namely the Japanese model, the American model and the European model:
1, the Japanese model
Features of this model are: carry out their duties, division level to complete turnkey projects. That robot manufacturers to develop new robots and production of quality products as the main target, its subsidiaries or social engineering by manufacturing companies to design complete systems for each robot industry needs and complete turnkey projects;
2, the European model
Features of this model are: a package of turnkey projects. That robot production and user needs design and manufacturing systems, all manufactured by robot manufacturers yourself;
3, American model
Features of this model are: purchasing and package design combined. The United States does not produce substantially conventional industrial robots, robot normally required when companies imported from engineering company, and then to design, manufacture supporting peripherals, complete turnkey projects.
From the beginning of the 1980s to carry out a comprehensive study of industrial robots in universities and research institutes, nearly 20 years to get a lot of scientific research. However, because there is no joint and businesses organically, has not yet formed a large scale industrial products and influential. At present, in addition to a main assembly of the Sino-Japanese joint venture robot outside the company, with independent intellectual property rights of industrial robots still remain in university or research institutes sporadic production organization, failed to form a climate. The past 10 years, a significant reduction in the price of imported robots, industrial robots for the development of China caused some impact, especially our own manufacturing of industrial robots in general simply can not compete on price. Especially in the early stages of the development of the robot, without the simultaneous development of the corresponding parts industry, the domestic enterprises in the production process of the robot, and can only rely on supporting the import of spare parts, but also weaken the price competitiveness of Chinese enterprises.
China's robotics industry should take what way, how to build their own model of development is indeed worth exploring. Chinese Academy of Engineering, completed and published in December 2003, "China's manufacturing industry Welding Production Situation and Development Strategy Research summary report" believes that China should "American model" to proceed, the conditions are ripe gradually to the "Japanese model" close.
Six robots Prospect in China
It should be said that China is a country and most do not need the robot is most needed. China's large population, rich resources and cheap labor, said that from this level with a more expensive and cumbersome robots might as well hire a person to come cheap, but our country to do the world powers have to do more things with the least resources, we companies must as far as possible the use of high technology to more efficient production, in order to win the highly competitive, which requires a lot of robots, robots are not as precise rate, accuracy and high efficiency. It may be unemployed, but more job creation, interest income will be more social. I believe that in the near future, the same car as the robotics industry will become a pillar industry of the national economy, the United States is a "national car" and China can become a "robot standing on the shoulders of the country."
Seven, hope and difficulty robot development
Robotics is an important part of high-tech, the process of industrialization in China has just started, has made some achievements, but there are still many difficulties and shortcomings, and therefore need a wide range of care and support.
National policy support, is to accelerate the industrialization of high technology an important prerequisite. According to China's relevant government departments should organize forces sufficient investigation, on this basis, to promote the development of practical application of robots and robot preferential policies to promote research and development. Such as taxation, investment and loans to support the implementation of the policy of the robot industry. The Japanese government through policy, adopted a series of measures to encourage enterprises to apply robots, robot development experience for the Japanese market, we can learn at home. In addition, the robot user, you can consider giving some financial subsidies to encourage purchases. In order to avoid the risk of accidents and occupational diseases caused by poor working conditions, protection of workers' physical and emotional security, for some special types of work, such as spraying, casting and other labor laws by forcing the use of industrial robots instead. This can greatly increase the number of demand for industrial robots.
Our robot industry must be pulled from the market. As a high-tech robot, its development is closely related to the production, the economic situation of society. Robot research and development only select the robot is technically much less likely to achieve the principle of priority application areas, and use it as a breakthrough, to other areas of infiltration, diffusion is essential.
Application of human machine to successfully onto the market, industrialization, or the needs of the joint efforts.
