“Please leave the room, close the door and start a disinfection,” says a voice from the robotic.
“It says it in Chinese as well now,” Simon Ellison, vp of UVD Robots, tells me as he demonstrates the machine.
Through a glass window we watch because the self-driving machine navigates a mock-hospital room, the place it kills microbes with a zap of ultraviolet gentle.
“We had been growing the business at quite a high pace – but the coronavirus has kind of rocketed the demand,” says chief government, Per Juul Nielsen.
He says “truckloads” of robots have been shipped to China, specifically Wuhan. Sales elsewhere in Asia, and Europe are additionally up.
“Italy has been showing a very strong demand,” provides Mr Nielsen. “They really are in a desperate situation. Of course, we want to help them.”
Production capability has tripled, and the staff now assembles one disinfection robotic a day at their facility in Odense, Denmark’s third largest metropolis – and residential to a rising robotics hub.
Glowing like gentle sabres, eight bulbs emit concentrated UV-C ultraviolet gentle. This destroys micro organism, viruses and different dangerous microbes by damaging their DNA and RNA, to allow them to’t multiply.
It’s additionally hazardous to people, so we wait exterior. The job is completed in 10-20 minutes. Afterwards there is a odor, very like burned hair.
“There are a lot of problematic organisms that give rise to infections,” explains Prof Hans Jørn Kolmos, a professor of medical microbiology, on the University of Southern Denmark, which helped develop the robotic.
“If you apply a proper dose of ultraviolet light in a proper period of time, then you can be pretty sure that you get rid of your organism.”
He provides: “This type of disinfection can also be applied to epidemic situations, like the one we experience right now, with coronavirus disease.”
The robotic was launched in early 2019, following six years of collaboration between mother or father agency, Blue Ocean Robotics and Odense University Hospital the place Prof Kolmos has overseen an infection management.
Costing $67,000 (£53,370) every, the robotic was designed to cut back the chance of hospital-acquired infections (HAIs) which might be expensive to deal with and trigger lack of life.
While there’s been no particular testing to show the robotic’s effectiveness towards coronavirus, Mr Nielsen is assured it really works.
“Coronavirus is very similar to other viruses like Mers and Sars. And we know that they they are being killed by by UV-C light,” he says.
Dr Lena Ciric, an affiliate professor at University College London and knowledgeable on molecular biology, agrees that UV disinfection robots can assist struggle coronavirus.
Disinfection robots aren’t any “silver bullet”, says Dr Ciric. But she provides: “These [machines] provide an extra line of defence.”
“We’re in the run up to having a lot of coronavirus patients in the various hospitals. I think it’s wise to be on top of the cleaning regimes… from an infection control point of view. “
To be absolutely efficient, UV must fall immediately on a floor. If lightwaves are blocked by dust or obstacles, such shadow areas will not be disinfected. Therefore guide cleansing is required first.
UV gentle has been used for many years in water and air purification, and utilized in laboratories.
But combining them with autonomous robots is a current improvement.
American agency Xenex has LightStrike, which must be manually put in place, and delivers high-intensity UV gentle from a U-shaped bulb.
The firm has seen a surge in orders from Italy, Japan, Thailand and South Korea.
Xenex says quite a few research present that it is efficient at decreasing hospital-acquired infections and combating so-called superbugs. In 2014, one Texan hospital used it within the clean-up after an Ebola case.
More than 500 healthcare services, principally within the US, have the machine. In California and Nebraska, it has already been put to make use of sanitising hospital rooms the place coronavirus sufferers obtained remedy, the producer says.
In China, the place the outbreak started, there was an adoption of latest expertise to assist struggle the illness.
The nation is already the best spender on drones and robotics programs, in line with a report from world analysis agency IDC.
Leon Xiao, Senior Research Manager at IDC China says robots have been used for a spread of duties, primarily disinfection, deliveries of medicine, medical gadgets and waste elimination, and temperature-checking.
‘I believe this can be a breakthrough for larger use of robotics each for hospitals and different public locations,” says Mr Xiao. However space in hospitals to deploy robots and acceptance by staff are challenges, he says.
The coronavirus has spurred home-grown Chinese robotics companies to innovate.
Shenzhen-based YouiBot was already making autonomous robots, and quickly adapted its technology to make a disinfection device.
“We’re making an attempt to do one thing [to help], like each one right here in China,” says YouiBot’s Keyman Guan.
The startup adapted its existing robotic base and software, adding thermal cameras and UV-C emitting bulbs.
“For us technically, [it’s] not as tough as you think about… really it is identical to Lego,” says Mr Guan.
It has supplied factories, offices and an airport, and a hospital in Wuhan. “It’s working proper now within the baggage corridor… checking physique temperature within the day, and it goes virus killing in the course of the night time,” he says. However the robot’s efficacy hasn’t yet been evaluated.
Meanwhile plant closures and other restrictions to curb coronavirus, have hampered getting parts. “The lack of 1 single part, [and] we can not construct a factor,” adds Mr Guan, though he notes things have improved in the last couple of weeks, the situation has improved.
“There aren’t many good issues to say about epidemics,” says Professor Kolmus, but it has forced industry “to seek out new options”.
