"Wow, it's cool!" On August 18, in the Jurui science and technology exhibition area of the 2022 World robot Expo, a group of students gathered their small heads together and stared at the single hole endoscopic surgery robot. When they saw that its "snake shaped arm" seemed to be the flexible hands of human beings that lightly peeled the egg shell of a quail egg, and the egg body was intact, they could not help but praise it. If this robot is used to assist doctors in surgery, it will not only extend the doctors' hands but also widen their eyes, making the minimally invasive surgery more accurate and flexible. Endoscopic surgery robot is known as the Pearl in the crown of robot field. For example, this single hole endoscopic surgical robot independently developed by China and breaking through the technical problem of "neck sticking" can be regarded as an outstanding medical robot in the world. Such a new robot is one of the representatives of many "high-end" technologies and products presented at the 2022 World robot Expo. The 2022 World robot Expo was held in Beijing Yichuang International Convention and Exhibition Center on the 18th. It will present more than 500 exhibits brought by more than 130 enterprises, and more than 30 new global products will be released on the spot. In addition, this Expo breaks the traditional idea of exhibition planning, insists on the application demand side as the guide, and innovates the new exhibition mode of "robot + application scenario". While showing the cutting-edge technology of robot products, the audience can more intuitively feel the changes brought by robot technology to production and life. Intelligent robots are liberating human hands. At this Expo, it can be seen that with the continuous progress of 5g, AI and computer control technology, robots are more intelligent and considerate. They are "taking over" people's complex and repetitive work and helping to complete many "impossible" tasks. The "robot new energy battery box intelligent production line" formed by the seven "blue industrial robots" at the exhibition stand of Sichuan Shougang has attracted much attention. Many spectators will appreciate their extraordinary skills and smart movements in the process of operating aluminum dual machine coordinated arc welding, floating constant force grinding of welds, 3D visual workpiece position recognition and other processes, and feel the high level of intelligence in modern robot system integration. It is reported that the system is also equipped with a "battery box production management system" to realize the data collection, storage and monitoring of robots and other equipment. Moreover, the visualization of production status, traceability of production information and pre judgment of maintenance information greatly enhance the core competitiveness of products. In the SRT soft robot exhibition area, it can be seen that various soft robots are using soft and flexible grippers to accurately grasp soft, abnormal and fragile sea cucumbers, grapes, glass and other items one by one, and then put them gently at the destination. From a close observation, it can be seen that the soft grippers are designed in imitation of ergonomics, light and sensitive, and some are driven like human thumb joints. They can give priority to reverse stretching and grasp various items flexibly and smoothly, which greatly liberates our hands. Continuously breaking through the technological bottleneck to benefit thousands of households has been a good development trend of China's intelligent robot industry, but most of the core parts are imported and the number of enterprises mastering the core technology of robots is still insufficient. At this Expo, it is gratifying to see that some
