What are the gaps between the current status of domestic robotics development and foreign countries?

Japan has obvious advantages in industrial robots, household robots, Europe leads in the field of industrial robots and medical robots, and the United States is mainly advantageous in the field of system integration, medical robots and defense and military robots. \x0d\ \x0d\ "South Korea attaches great importance to service type (such as education, entertainment) robots, dominating the standards of this type of robots; the United States dominates high-end robots, such as exploration, explosion-proof light function robots; Japan's industrial robots are very good and cheaper than ABB; and Sweden's ABB represents the technology of Europe, with a very good workmanship, and has the most complete The best industrial chain." Guangzhou CNC deputy chief engineer He Yingwu said. \x0d\ \x0d\ "Reducer is click high-speed operation needs to use it to reduce the speed into the robot applicable speed. Generally a robot body generally have 6 reducer, 1 to 3 axis with the Japanese Teijin imported reducer, this company's reducer almost all over the world, 4 to 6 axis with our self-developed reducer. But our reducer is not mature enough for mass production yet." \x0d\\\x0d\\ Currently, the upstream of the robot has the highest profit value, just the reducer accounts for about 35% of the cost of the robot, and the motor and controller part accounts for about 10%. Domestic robot body due to the high cost of key components, gross profit rate negative value outside, the robot industry chain of all links are to maintain a relatively high level of gross profit rate, which to the highest level of medical surgical robot gross profit rate close to more than 70%. \x0d\ \x0d\ Currently domestic robots use reducers, servo motors and drives are still mainly supplied from abroad, of which Japan is the largest exporter of reducers. The domestic development of reducer listed companies as well as to be listed companies are Qinchuan development and Huaheng welding, Huichuan technology, INVISTA, KeYuan shares, Huazhong numerical control development drive. In the unlisted companies, Guangzhou CNC and Nanjing Exton in addition to reducer is not mass production, robotics in all aspects are involved. \x0d\ \x0d\ Robot body producers such as Shanghai Mechatronics, Qinchuan Development, Suzhou Lvxin, Nantong Zhenkang and other enterprises are using joint ventures or independent research and development, is actively entering the field of precision reducers. But the current domestic market competition is very fierce, foreign brands and domestic brands joint venture research and development is unlikely, because it involves core technology, foreign brands are unlikely to leak.
