　　1、 Overview of Industrial Robots

　　1. Definition

　　Industrial robots are widely used in the industrial field as multi joint robotic arms or multi degree of freedom machine devices. They have a certain degree of automation and can rely on their own power and control capabilities to achieve various industrial processing and manufacturing functions. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemical engineering.

　　2. Classification

　　Industrial robots can be divided into programming input robots and teaching input robots according to the input signal method. According to the form of motion coordinates, it can be divided into articulated machines, cylindrical coordinate robots, Cartesian coordinate robots, parallel robots, and SCARA (planar joint type) robots. According to the driving method, it can be divided into hydraulic driven robots, pneumatic driven robots, and electrical driven robots.

　　2、 Industrial Chain Structure and Analysis

　　1. Industrial chain structure

　　After decades of development, China's industrial robot industry has formed a complete industry chain. Upstream components, as raw materials, are extremely important for industrial robots. The three core components are control systems, servo systems, and reducers. The midstream is the robot body, while the downstream is the integrated system, which is widely used in industries such as automobiles, 3Cs, food, and beverages.

　　2. Upstream analysis

　　The three core components with the highest technical difficulty in industrial robots are reducers, servo systems, and controllers, which respectively account for 35%, 25%, and 10% of the cost composition of industrial robots. The cost of core parts accounts for 70% of the total cost of industrial robots, and core parts suppliers have the strongest Bargaining power in the entire industrial chain. At present, 85% of the reducer market, 90% of the servo motor market, and over 80% of the control system market in China are occupied by overseas brands.

　　3. Downstream analysis

　　In the downstream industry of industrial robots, the automotive industry has the highest proportion of downstream applications of industrial robots, accounting for approximately 35% of the total industrial robot market shipments, with applications in automotive parts and automotive vehicles accounting for 23% and 12% respectively. According to data, in the first half of 2021, China's automobile production reached 12.79 million units, an increase of 26.4% compared to the first half of 2020.

　　3、 Industry development status

　　1. Production and market size

　　With the rapid development of traditional industries, especially manufacturing, in China, the demand for production labor is gradually increasing. However, with the further aggravation of the aging of the population, the Demographic dividend is gradually receding, and the human cost is rising year by year. The demand of traditional industries, especially manufacturing industries, for labor substitute products such as industrial robots will always keep growing. In addition, due to the impact of the epidemic, other countries have shut down production, while China has effectively controlled the epidemic, so it has taken on a large amount of production and manufacturing demand from around the world, promoting a small peak in the domestic manufacturing industry, indirectly driving the growth of the industrial robot industry. According to data, the production of industrial robots in China in the first half of 2021 was 173630 sets, an increase of 69.8% compared to the first half of 2020.
