In a different article today at IEEE Spectrum Magazine, Evan Ackerman
reports on how a Danish company called UVD Robots is making robots
that are able to disinfect patient rooms and operating theaters in hospitals.
The Danish company is on a winner and can't ship them fast enough.
Additional markets in the future include cruise ships, GP surgeries
dental surgeries, nursing homes, day care centres, schools.

The company’s robots have been operating in China for the past two or three weeks, and UVD Robots CEO Per Juul Nielsen says they are sending more to China as fast as they can. “The initial volume is in the hundreds of robots; the first ones went to Wuhan where the situation is the most severe,” Nielsen told IEEE Spectrum. “We’re shipping every week—they’re going air freight into China because they’re so desperately needed.” The goal is to supply the robots to over 2,000 hospitals and medical facilities in China.

It takes between 10 and 15 minutes to disinfect a typical room, with the robot spending 1 or 2 minutes in five or six different positions around the room to maximize the number of surfaces that it disinfects. The robot’s UV array emits 20 joules per square meter per second (at 1 meter distance) of 254-nanometer light, which will utterly wreck 99.99 percent of germs in just a few minutes without the robot having to do anything more complicated than just sit there. The process is more consistent than a human cleaning since the robot follows the same path each time, and its autonomy means that human staff can be freed up to do more interesting tasks, like interacting with patients.
Originally, the robots were developed to address hospital acquired infections, which are a significant problem globally. According to Nielsen, between 5 and 10 percent of hospital patients worldwide will acquire a new infection while in the hospital, and tens of thousands of people die from these infections every year. The goal of the UVD robots was to help hospitals prevent these infections in the first place.

Over the next few weeks, they’ll be tested at other medical facilities around the United States, and Nielsen points out that they could be useful in schools, cruise ships, or any other relatively structured spaces.
