mechatronics can be roughly divided into three stages. The first stage was before the 2060s, and this stage is called the primary stage. During this period, people consciously or unconsciously use the initial results of electronic technology to improve the performance of mechanical products. Especially during the Second World War, the war stimulated the combination of mechanical products and electronic technology. These electromechanical military technologies were converted to civilian use after the war, which played a positive role in the recovery of the post-war economy. At that time, research and development were still in a spontaneous state on the whole. Since the development of electronic technology had not yet reached a certain level at that time, the combination of mechanical technology and electronic technology could not be widely and deeply developed, and the products that had been developed could not be widely promoted.

1970 s and 1980 s are the second stage, which can be called the vigorous development stage. During this period, the development of computer technology, control technology, and communication technology laid a technical foundation for the development of mechatronics. The rapid development of large-scale, ultra-large-scale integrated circuits and microcomputers provides a sufficient material basis for the development of mechatronics. The characteristics of this period are: ① The word mechatronics was first widely accepted in Japan, and it was widely recognized worldwide around the end of the 1980 s; ② mechatronics technology and products have been greatly developed; ③ All countries have begun to pay great attention and support to mechatronics technology and products.
