UVD Robots
HISTORY:
UVD Robots ApS was founded in 2016 by Blue Ocean Robotics
with the objective of global commercialising robotic based UV
Disinfection solutions for hospitals. The incorporation of the
company followed a Private Public Innovation project starting
in 2014, where Blue Ocean Robotics and Odense University
Hospital OUH in partnership with other hospitals in Denmark,
developed the first prototype of the UV-Disinfection Robot,
with the objective of preventing Hospital Acquired Infections
(HAI’s) for the benefit of patients, hospital staff and associated
healthcare costs.

The UVD Robot is used as part of the regular cleaning cycle, and
aims at preventing and reducing the spread of infectious
diseases, vira, bacteria, and other types of harmful organic
microorganisms in the environment by breaking down their
DNA-structure. The robot is safe, reliable and eliminates human
error.
UVD Robots philosophy is centred around integrating proven
UV germicidal industrial solutions with new advanced robot
technologies, creating innovative products helping the
healthcare industry in the eradication of harmful pathogens
and superbugs, thereby making healthcare environments safer
and improving quality of care for hospitals and healthcare
facilities around the world.

UVD Robot is designed to be used as part of the hospital’s
regular cleaning process and aims at preventing and reducing
the spread of infectious diseases, vira, bacteria, and other types
of harmful organic microorganisms in the environment by
breaking down their DNA-structure. The robot is safe, reliable
and eliminates human error, and always gives an accurate
repeated process. Furthermore, it is user friendly and is
designed to be operated by nursing staff and cleaning
operatives.
The UVD Robot has been clinically tested and verified at
Odense University Hospital and Danish Technological institute.
It has also been tested by the UK independent microbiological
laboratories, Melbec Microbiology.
The advantages of the UVD Robot over existing manual systems
is the incorporated, fully autonomous technology, allowing the
robot to move position without human interaction, drastically
reducing shadow areas. Increased mobility ensures closer

proximity to all high touch surfaces, increasing the intensity of
the UV-C light.
Advanced Technology Of UVD Robots:
UVD Robots advanced technology gives the ability to disinfect
thousands of critical surfaces on a massive scale, absolutely
anywhere, at any time, without creating extra work for cleaning
operatives. The UVD Robot is able to operate over thousands of
sq. metres, totally autonomously, manoeuvring around
obstacles that cause shadows and getting within 1 metre
distance from all high touch surfaces where the UV-C light is
most effective. Even when moving between positions at 10
centimetres per second, the UVD Robot is still disinfecting
medium and low touch surfaces as is passes by.
The laws of physics govern UV-C light. Shadowing and distance
to surface have limitations. This is not the case for the UVD
Robot, as it can reposition itself to minimise shadow and
reduce the radiation distance. When the disinfection process is
complete the robot will compile a comprehensive disinfection
report for your records.
In March 2019, a leading NHS Hospital performed something
never seen in infection control – the full disinfection of a 2,000
m2 Outpatient Oncology department in a staggering 90
minutes. Even more impressive was the fact that this
disinfection was carried out with zero human interaction. In
comparison, two weeks previous, the very same disinfection
process was carried out by staff using a manual UV-C system.
This had taken up to 20 hours of personnel time. The
disinfection plan with the UVD Robot was an identical copy of

the manual version, except that unlike the manual version, the
UVD Robot continued to disinfect whilst moving position.
UVD Robots spent four years developing a robotic UV
disinfection system, which it started selling in 2018. The robot
consists of a mobile base equipped with multiple lidar sensors
and an array of UV lamps mounted on top. To deploy a robot,
you drive it around once using a computer. The robot scans the
environment using its lidars and creates a digital map.
After that, the robot relies on simultaneous localization and
mapping (SLAM) to navigate, and it operates completely on its
own. It’ll travel from its charging station, through hallways, up
and down elevators if necessary, and perform the disinfection
without human intervention before returning to recharge. For
safety, the robot operates when people are not around, using
its sensors to detect motion and shutting the UV lights off if a
person enters the area.

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.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.
