On February 2, 2022, in the theme activity of the torch relay of the 2022 Winter Olympics held in Beijing Winter Olympics Park, the robot developed by China completed the first underwater torch relay of robots in the history of the Olympic Games! When the two robots successfully docked their torches in the water, the applause thundered. Authoritative experts say that the difficulty coefficient is comparable to that of electric bed docking!
During the torch relay, the torchbearer handed the Olympic flame to an amphibious robot, which lit the torch and slid into the ice cave along the curling track. An underwater variable structure robot looks at it, and two robots hold torches to hit the fire accurately in the water; The underwater deformable robot holds the amount of water to ignite the torch from the edge of the ice cave and passes the Olympic flame to the next torchbearer.
Under the key application of the national key R&D plan "High-tech Winter Olympics" of the Ministry of Science and Technology, Shenyang Institute of Automation, China Academy of Sciences, jointly developed the underwater torch relay robot with Beijing Institute of Power Machinery and Guangdong Institute of Intelligent Unmanned Systems. The elite team of scientific research gathered wisdom and technology to tackle key problems, and perfected the core technologies such as high adaptive motion control of cold water across materials, dynamic direction of complex potential flow oscillation in water, centimeter-level precision work of underwater manipulator and reliable ignition mechanism across materials, and completed the underwater torch relay of this Winter Olympics.
"The precise docking of robots under the ice and the fire in the water are not only a highlight of the robot's cross-domain request for torch relay, but also a big problem, and its difficulty coefficient is comparable to that of electric bed docking." Dr. Tian Qiyan, the project manager of the key project of "High-tech Winter Olympics", a national key scientific research development plan, said: "Multi-robot cross-domain request and system software demonstration application of torch relay technology research".
Different from other torches, amphibious robots hold the world's first green torch, which can clean water and air without smoke. It is precisely because of this that it can complete underwater docking and lighting.
The special torch carried by the robot can supply oxygen independently in front of the kitchen sewer, so it can be used in water without relying on o2 in the air. 3 1 Institute of the Third Institute of China Aerospace Science and Industry Group has carried out a professional design scheme for the burner, maintaining the flame according to the physical structure and aerodynamic characteristics of the burner and avoiding the damage of the water environment to the flame.
In order to integrate into the natural environment of the site and ensure foolproof docking, the on-site elite team settled in Beijing Winter Olympics Park early to race against time to improve the daily tasks of the robot torch relay. Nearly hundreds of tests were carried out in 25 days, which further improved the control characteristics and reliability of the robot.
Tian Qiyan, project manager and associate researcher of Shenyang Institute of Automation, a key national scientific research and development plan "High-tech Winter Olympics", told reporters: "Although I am in the cold winter, I have been sweating because of anxiety and excitement."
"This theme event completed the underwater torch relay race for the first time in the world and ignited everyone's enthusiasm for the Beijing Winter Olympics. At the same time, it conveyed friendship and friendship to the whole world, and at the same time presented the scientific and technological innovation of the robot industry in China. " Li Shuo, deputy director of Shenyang Institute of Automation, said.
It is understood that the elite team of scientific research has also developed aerial flying robots, road robots and snow hexapod robots. , and participated in laboratory tests and off-site experiments successively, and conducted off-site experiments in Shenyang and Beijing, providing high-quality technical and weapons and equipment support points for the torch relay of Beijing Winter Olympics.
