Intelligent disinfection robot stands at the Winter Olympics epidemic prevention post

The striving China once again ignited the flame of passion and dreams, and the Beijing Winter Olympics, which the world has been eagerly awaiting, opened on February 4.

"Water Cube" becomes "Ice Cube", "100-meter-level, minute-level" accurate weather forecast, the world's largest single-layer two-way orthogonal saddle-shaped cable net roof of the National Speed Skating Stadium, 5G signal covering all venues, 8K competitions Real-time transmission of pictures... The Winter Olympics of Science and Technology is the main feature of the Beijing 2022 Winter Olympics and Winter Paralympics.

The website of China Association for Science and Technology has opened a special topic "Backstory of the Winter Olympics of Science and Technology" to explore the behind-the-scenes stories and heroes of the high-tech Winter Olympics, and to show the hard work and dedication of the national societies affiliated to the China Association for Science and Technology and the vast number of scientific and technological workers in the "Winter Olympics of Science and Technology". , innovation, and transcendence, recording the touching story of scientific and technological workers helping the Beijing Winter Olympics ice and snow epic.

Without protective clothing and goggles, it is a brave and silent "killing guard" who replaces human beings to eradicate the new crown virus.

Lock on the target, wave the arm forward, front and back, left and right, the next target... At the entrance of the athletes' locker room at the Beijing 2022 Winter Olympics National Stadium, an intelligent disinfection robot equipped with a robotic arm is proficiently and autonomously applying deep ultraviolet rays to all desktops in sequence. kill.

"The role of the robot is to replace the human operation of deep ultraviolet equipment and implement surface disinfection or air disinfection in dangerous or potentially dangerous areas to reduce cross-infection and protect human health." Zhao Xiaoguang, a member of the Chinese Society of Automation and a researcher at the Institute of Automation, Chinese Academy of Sciences, said.

Different from ordinary disinfection robots, when facing the surface of complex objects, this intelligent disinfection robot can not only recognize the shape of the object adaptively, but also independently plan the disinfection trajectory to achieve efficient and accurate killing effect. Work in a human-operated environment.

Behind this, it is based on ultraviolet chip technology, multi-degree-of-freedom robotic arm technology, binocular visual recognition technology, and intelligent control technology.

        "The robotic arm intelligent disinfection robot belongs to the type of powerful surface disinfection. The disinfection equipment held by the robot can generate deep ultraviolet rays of 265-275 nanometers. It only takes 3-5 seconds of irradiation to kill more than 90% of the bacteria and viruses on the surface of the object. " Zhao Xiaoguang said.

But this also puts forward higher requirements for the intelligent degree of robots. It not only needs a high level of autonomous perception, it can accurately identify whether the target object is a person or a thing, but also make decisions and execute autonomously, plan where to kill, where to start, and where to end, and complete the entire task by itself.

In addition to the robotic arm intelligent disinfection robot, Zhao Xiaoguang's team also cleverly combined intelligent robots with excimer disinfection lamps to jointly assist the epidemic prevention work of the Beijing Winter Olympics and Winter Paralympics.

Excimer disinfection lamps, known as "light vaccines" in many media reports, can emit ultraviolet rays with a wavelength of 222 nanometers to disinfect the irradiated air without causing harm to the human body.

     When everyone was impressed by the "magic" effect of excimer disinfection lamps, Zhao Xiaoguang was already thinking about how to combine excimer disinfection lamps with intelligent robots to achieve more efficient, convenient and mobile disinfection.

"Deep ultraviolet disinfection equipment is actually a disinfection tool, and robots are used to replace human beings to use tools to protect personnel safety and reduce labor." Zhao Xiaoguang said.

In order to get the intelligent disinfection robot "on duty" for the Beijing Winter Olympics as soon as possible, she led the team to invest in scientific research against time.

In fact, the State Key Laboratory of Complex System Management and Control, Institute of Automation, Chinese Academy of Sciences, where Zhao Xiaoguang's team is located, has accumulated more than 30 years of experience in intelligent robots, and she herself has been deeply involved in this field for more than 20 years. For them, the robotic design process is a bigger challenge than a technical challenge.

"During that time, we all put down other work in our hands and concentrated on the detailed design of the robot, because once it reaches the processing stage, it means to increase the cost, so we have to scrutinize many details repeatedly, and only contact the factory after the final draft is finalized. Processing." Zhao Xiaoguang recalled.

Although the two intelligent disinfection robots that have been "on duty" have shown excellent work ability, there is one thing that Zhao Xiaoguang is not very "satisfied" with, and that is their "appearance".

"They are not very good-looking, not so cute." Zhao Xiaoguang said, "If you consider the appearance after the functional design is completed, you will feel that no matter what is installed, it will be wrong. Product designers should be integrated into the team from the beginning, so that the robot is practical and beautiful. ."

Zhao Xiaoguang said that the next step will continue to improve the design process of intelligent disinfection robots, reduce costs, and let disinfection robots enter people's daily life as soon as possible. "We hope that the intelligent robot system will achieve continuous breakthroughs from theory to practice in various application scenarios, and ultimately make robots more and more intelligent and help humans do more things."
