UV-C robots: the disinfection of the future?

Shery George | 15 September 2021

Especially now, preventive hygiene measures, or hygiene management, are in the spotlight.
Especially in public facilities such as hotels, schools or hospitals, they play an indispensable
role. Disinfection robots can provide a remedy here. But how safe is this new technology and
is the use of robots worthwhile for public institutions? Time to take a closer look at the topic.

Classical disinfection measures regularly reach their limits in the case of germs

Well-functioning hygiene management is indispensable in hospitals, as poor hygiene leads to the transmission of diseases. Hospital germs are a great danger to our health, especially for patients with weakened immune systems. For this reason, patient rooms, operating theatres and waiting rooms should not only be disinfected regularly but thoroughly. The major disadvantage of classical scrub-and-wipe disinfection, in which disinfectants are applied to surfaces by staff, is the development of resistance by germs to the disinfectants used.

UV-C robots revolutionise disinfection

UV-C radiation is a high-energy, short-wave radiation and is produced by filtering it out via the
ozone layer. It is able to deactivate any bacteria and viruses by penetrating deep into the DNA
or RNA of the appropriate germ and damaging it. With this process, germs can be neutralised
on surfaces and even in the air.
Autonomous disinfection robots could become a standard hygiene measure in the future,
especially in public facilities. The robots equipped with UV-C light can move autonomously
through rooms and clean them thoroughly within a few minutes. A major advantage of the
robots is that they are environmentally friendly and do not harm health. In the passageway,
they are supposed to disinfect the air and surfaces without the use of alcoholic or chemical
agents. Before use, due to current safety regulations, one person must ensure that the room
is free of people and ready for use.

Cost-effective disinfection robots in Low Cost Automation – Test before invest

In our igus Customer Testing Area we built and tested a prototype of a UV-C robot at the
request of a customer. The robolink DP with UV-C light travels on a drylin ZLW linear unit, the
so-called seventh axis, for more freedom of movement for the robot.

Mobile robot platforms from various manufacturers are suitable for mobile robot solutions. You
can find them on RBTX, our online marketplace for low-cost robotics.

The robot is controlled quite simply by the aid of the igus Robot Control system. In a short
learning phase, the robot is moved into the room with a joystick or via a tablet, so that it can
find all the target objects there, e.g. scan and memorise furniture using laser sensors.
The igus Robot Control is particularly suitable for beginners and requires no special
programming knowledge.

Conclusion: the past year in particular has shown the important role that preventive hygiene
measures play, of course also in post-pandemic times. Let us not forget the lessons of the
past year; let us be prepared for new viruses that may come. Fortunately, more and more
manufacturers are offering solutions to optimise hygiene measures and nip bacteria and
viruses in the bud. The technologies are already there, it is up to us to recognise and use
them as standard.
Low Cost Automation offers a wide product range of cost-effective and flexible automation
solutions. Especially for newcomers to robotics and automation, the purchase of a robot
system is associated with many questions and potential risks. For individual advice or a free
