Robot technology and system for precise manipulation of living cells

Key words: robot technology; Micromanipulation; Cell manipulation; Animal cloning

Live cell manipulation is of great significance to the development of biomedicine and the solution of key core problems in agricultural breeding, and the demand is growing rapidly. Facing the urgent needs of the development of life science, Nankai University develops the technology and system of living cell precision operation robot, aiming to realize the automatic living cell operation by using robot instead of human. Living cells are alive, with the characteristics of low operation success rate, low survival rate after operation, and low subsequent development rate, which poses great challenges to robot technology. This development provides an automated cell operating system for life science research and achievement promotion, and has wide application value. Research and development of precision fixed-point operation technology based on minimum force, precision minimally invasive operation technology based on minimum strain, quantitative nucleation operation technology for minimum nucleation, and the development of domestic living cell precision operation robot system. The results have been applied in biomedicine and brain science research, and have been applied in 14 units.

02The nuclear fuel assembly is autonomous

Key manufacturing technology and complete sets of equipment

Key words: nuclear fuel assembly; Manufacturing technology; Equipment development

As the most important reactor components in the nuclear island and the strategic basic components of the nuclear industry, nuclear fuel components have a significant impact on the national energy strategy of “safe and efficient development of nuclear power” and the safety of the nuclear industry. Facing the major needs of the country, after more than 10 years of industry-university-research joint research, Hunan University has carried out systematic research on the key intelligent manufacturing technologies of the whole chain of nuclear fuel from “pellet” to “component” to “component”, conquered a series of key common technologies and core intelligent manufacturing processes, and developed complete sets of intelligent equipment, including: key common technologies for radiation damage reliability analysis and design; Grinding and manufacturing process and automatic equipment for the preparation of nuclear fuel pellets; The grid strip progressive die punching process and intelligent equipment for the assembly of nuclear fuel assemblies. This scientific and technological progress independently develops a total of 8 types of key processes and 11 types of serialized high-end equipment/equipment in 3 aspects of pellet preparation, component manufacturing and component assembly, supports the construction of 5 backbone production lines of nuclear fuel assembly in China, promotes the core capability construction of “China core” in China’s nuclear industry, and forms a complete technology, process and equipment system. The relevant research results have strongly promoted the important transformation of China’s nuclear fuel assembly manufacturing from being subject to others to the overall technology autonomy and control, and provided a strong guarantee for the safety of the nuclear industry and the national energy strategy.

03Integrated development of gas turbine life cycle

Research and application of key technologies

Key words: gas turbine; Digital factory; Full life cycle digitization

Shortlisted reasons: Gas turbine is a national instrument, is involved in national defense security and energy security of the strategic high-end equipment, in the field of ship power, distributed energy and power generation has an irreplaceable strategic position and role. The 73rd Research Institute of China State Shipbuilding Corporation Limited and CSIC Longjiang Guanghan Gas Turbine Co., Ltd. jointly study the integrated development of the whole life cycle of gas turbines and the innovative integration of the new generation of information technology, and use digital technology to enable the development of gas turbines in all aspects, all angles and all chains, and improve the total factor productivity. Through nearly 10 years of construction practice, the company has solved core technical problems such as gas turbine design, manufacturing and maintenance, successfully developed industrial gas turbines with independent intellectual property rights, and realized applications in natural gas transmission, oil and gas exploitation, distributed energy, emergency power supply and other fields. This scientific and technological progress aims to comprehensively build a gas turbine digital factory, build a digital and intelligent innovation chain for the whole life cycle of gas turbines, realize the digitization of R&D design, visualization of manufacturing process, test data assets, and intelligent service guarantee, shorten product R&D cycle by 30%, increase production capacity by more than double, and reduce the cost of a single gas turbine by about 6 million yuan.

04Digital management of the whole process of rice production

And intelligent equipment industrialization

Key words: rice intelligent production; Intelligent agricultural machinery; Digital management platform; Decision model

Reasons for shortlisting: Zhonglian Agricultural Machinery Co., LTD., Zhonglian Intelligent Agriculture Co., LTD., National Agricultural Intelligent Equipment Engineering and Technology Research Center and Anhui Zhongke Intelligent Sensing Technology Co., LTD., take rice production as the object, the whole process uses five links of intelligent agricultural machinery equipment and digital management: ploughing, planting, management, harvesting and storage. By solving the problems of low intelligence level of rice production, lack of digital management, and non-integration of agricultural machinery and agronomic data, rice production has changed from “relying on the sky to eat” to relying on intelligent equipment and relying on scientific decision-making basis for the whole process of digital management of agricultural production. The whole process of rice production uses satellite laser leveling technology, so that the flatness of the land does not exceed 3cm; In the planting process, the technology of unmanned orderly seedling throwing machine was adopted to replace manual and shorten the slow green period of seedlings to achieve yield increase. The artificial intelligence harvester realizes self-adaptive adjustment and low-loss harvest according to information such as crop posture, soil environment and weather conditions; In the transportation link, after the automatic unloading of grain by the unmanned grain truck and the harvest machine, the grain is transferred to the intelligent drying center, and the rice moisture drying curve control technology is used to reduce the burst waist rate and reduce the internal injury of the grain, thereby increasing the rice yield and maintaining the grain quality. In the production process, with the digital management platform, the decision-making model of soil, pests and diseases, and fertility is built, and the identification accuracy of disease, insect and grass damage and water growth is more than 90%, and the precision spraying, variable topdressing, intelligent irrigation and the whole process monitoring of crop growth are realized. The whole process of intelligent equipment and technology application, can reduce farming operations by 30% to 40% per acre; Reduce pesticide input about 20 yuan; Reduce all kinds of fertilizers 20-30 yuan; Water saving about 30%; The carbon sink is about 1.8~2 tons, and the benefit is significant.
