"Please leave the room, close the door and start a disinfection," says a voice from the robot.
"It says it in Chinese as well now," Simon Ellison, vice president of UVD Robots, tells me as he demonstrates the machine.
Through a glass window we watch as the self-driving machine navigates a mock-hospital room, where it kills microbes with a zap of ultraviolet light.
"We had been growing the business at quite a high pace - but the coronavirus has kind of rocketed the demand," says chief executive, Per Juul Nielsen.
He says "truckloads" of robots have been shipped to China, in particular Wuhan. Sales elsewhere in Asia, and Europe are also up.
"Italy has been showing a very strong demand," adds Mr Nielsen. "They really are in a desperate situation. Of course, we want to help them."

Production has been accelerated and it now takes less than a day to make one robot at their facility in Odense, Denmark's third largest city and home to a growing robotics hub.
Glowing like light sabres, eight bulbs emit concentrated UV-C ultraviolet light. This destroys bacteria, viruses and other harmful microbes by damaging their DNA and RNA, so they can't multiply.
It's also hazardous to humans, so we wait outside. The job is done in 10-20 minutes. Afterwards there's a smell, much like burned hair.
"There are a lot of problematic organisms that give rise to infections," explains Prof Hans Jørn Kolmos, a professor of clinical microbiology, at the University of Southern Denmark, which helped develop the robot.
"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 adds: "This type of disinfection can also be applied to epidemic situations, like the one we experience right now, with coronavirus disease."

The robot was launched in early 2019, following six years of collaboration between parent firm, Blue Ocean Robotics and Odense University Hospital where Prof Kolmos has overseen infection control.
Costing $67,000 (£53,370) each, the robot was designed to reduce the likelihood of hospital-acquired infections (HAIs) which can be costly to treat and cause loss of life.
While there's been no specific testing to prove the robot's effectiveness against coronavirus, Mr Nielsen is confident it works.
"Coronavirus is very similar to other viruses like Mers and Sars. And we know that they are being killed by UV-C light," he says.

Dr Lena Ciric, an associate professor at University College London and expert on molecular biology, agrees that UV disinfection robots can help fight coronavirus.
Disinfection robots are no "silver bullet", says Dr Ciric. But she adds: "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 fully effective, UV needs to fall directly on a surface. If lightwaves are blocked by dirt or obstacles, such shadow areas won't be disinfected. Therefore manual cleaning is needed first.
UV light has been used for decades in water and air purification, and used in laboratories.
But combining them with autonomous robots is a recent development.
XENEX
American firm Xenex has LightStrike, which has to be manually put in place, and delivers high-intensity UV light from a U-shaped bulb.
The company has seen a surge in orders from Italy, Japan, Thailand and South Korea.
Xenex says numerous studies show that it's effective at reducing hospital-acquired infections and combating so-called superbugs. In 2014, one Texan hospital used it in the clean-up after an Ebola case.
More than 500 healthcare facilities, mostly in the US, have the machine. In California and Nebraska, it has already been put to use sanitising hospital rooms where coronavirus patients received treatment, the manufacturer says.
In China, where the outbreak began, there has been an adoption of new technology to help fight the disease.
The nation is already the highest spender on drones and robotics systems, according to a report from global research firm IDC.
Leon Xiao, Senior Research Manager at IDC China says robots have been used for a range of tasks, primarily disinfection, deliveries of drugs, medical devices and waste removal, and temperature-checking.
'I think this is a breakthrough for greater use of robotics both for hospitals and other public places," says Mr Xiao. However space in hospitals to deploy robots and acceptance by staff are challenges, he says.
YOUIBOT
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 trying to do something [to help], like every one 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 difficult as you imagine… actually it's just like Lego," says Mr Guan.

It has supplied factories, offices and an airport, and a hospital in Wuhan. "It's running right now in the luggage hall… checking body temperature in the day, and it goes virus killing during the night," 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 one single component, [and] we cannot build a thing," adds Mr Guan, though he notes things have improved in the last couple of weeks.
"There are not many good things to say about epidemics," says Professor Kolmus, but it has forced industry "to find new solutions".

Los Angeles-based Dimer UVC Innovations, which develops the GermFalcon germ-killing robot aimed at sanitizing airplanes, today offered to provide its services to three U.S. airports to help address an outbreak of a pneumonia-like illness that originated in China.
The coronavirus, which is in the same family as severe acute respiratory syndrome (SARS), has spread to 473 patients in China, and that 17 people have died from the virus. In the U.S., officials at the U.S. Centers for Disease Control and Prevention confirmed one case of a Washington State resident testing positive for the virus after a trip to China.

Dimer said its GermFalcon robot was specifically created to improve airplane hygiene, using ultraviolet-C (UVC) light to kill viruses, bacteria, and “superbugs on surfaces and in the surrounding air.” The GermFalcon is also designed to navigate an airplane cabin, with strategically placed UVC lamps that can expose all high-touch surfaces to the UVC light.
The company said it will offer the germ-killing system to “contribute to emergency response efforts at the Los Angeles International Airport (LAX), San Francisco International Airport (SFO), and John F. Kennedy International Airport (JFK) in New York.
“The threat of coronavirus infecting innocent passengers on an airplane is one we must work to eliminate immediately,” said Elliot Kreitenberg, co-founder of Dimer. “This is a dangerous virus that has already taken lives. GermFlacon is a fast and effective response to this threat, and we are pleased to offer it at no expense to contribute to emergency response efforts at LAX, SFO, and JFK airports during this crisis.”

UVC disinfection robots are typically seen in healthcare facilities and hospitals, being used to disinfect air, water, and surfaces in rooms and operating rooms. Companies in this space include Tru-D (recently acquired by PDI Healthcare), XENEX Disinfection Services and its LightStrike Robots, and UVD Robots, a spinoff from Denmark’s Blue Ocean Robotics robot incubator. A spokeswoman for UVD Robots said several partners of the company in Asia are collaborating with health authorities in the region to disinfect larger areas in airports, as the robot is too large to be used inside an airplane.
The outbreak in China originated in Wuhan, and centered on a seafood market. The CDC said while originally thought to be spreading from animal-to-person, “there are growing indications that limited person-to-person spread is happening.” But it also noted that it was unclear on how easily the virus is spreading between people.
The CDC said it began implementing public health entry screening at SFO, JFK and LAX airports on Jan. 17, and will add entry health screening at two more airports – Atlanta (ATL) and Chicago (ORD). The agency is providing updates on the outbreak at this site.
