The emergence of robots has a major impact on the industry 4.0 technology. At present, many industrial robots are gradually replacing human work. As the production robots adopting digital technology, Internet of Things technology and intelligent circuits using high-precision resistors as important components, the robot operation becomes more flexible. The industry is entering the era of smart manufacturing, and the smart factory pattern has also changed, and it will develop toward “human-machine cooperation factories” and “unmanned factories”.
   
As fully automated production and assembly lines are used to some extent, the task assignment between people and machines will become a common problem in the near future. The entire production activity of the unmanned factory is controlled by an electronic computer, and the first line is equipped with a robot without a factory equipped with workers. In this factory, production orders and raw materials are imported from one end of the plant, through product design, process design, production processing and inspection packaging, and finally the product is output from the other end of the plant. 

 
At present, the most perfect robot application field in China is the development of automobile production and fast-track logistics industry. The logistics industry robots use smart chips and precision resistors and shunts to form high-precision intelligent circuits, which can accurately sort out different regions. This kind of robot usage rate is increasing every year in China, which can save a lot of manpower for the logistics industry. Under the background of rising labor costs and improving working conditions, there will be more and more “unmanned factories” in the world factory in China. It will be born, and China will realize the transformation and upgrading of the manufacturing industry.
