The COVID-19 pandemic has brought upon a new normal that is not only impacting our health and social lives, but is also disrupting businesses and economies globally. Other than respiratory droplets, COVID-19 can also be acquired through contact with surfaces contaminated with SARS-CoV-2, the virus that causes COVID-19.
Studies* indicate that the virus can remain on surfaces from a timeframe of a few hours to multiple days, thus highlighting the risk of fomite-mediated transmission and the necessity of disinfecting the premises thoroughly.

While using traditional manual cleaning and disinfection practices, organizations face many challenges such as variation in the performance of individual housekeepers, inappropriate use & availability of disinfectants, access to desired number of manpower around the clock and the complicated disinfection requirements of high-touch areas. All these necessitate the need of augmenting the manual cleaning regime with UVC disinfection.
The LD UVC is one of our unique solutions, designed specifically to fight the COVID-19 outbreak. It is used for disinfecting rooms and high-touch surfaces automatically and effectively.
Individually validated UVC lamps deliver balanced and uniform high-output UVC flux to disinfect surfaces from pathogens.
With the seamless integration of our software, the robot is easy to get up and running; requires minimal programming time.
Safety lasers, emergency stop function, PIR motion sensors detect human presence and shut the UV lamps automatically.
UVC light breakdowns the DNA and RNA chains of the cells of the micro-organisms beyond recovery. This disables the function of the cell and eventually kills it.
Although manual cleaning is still the mandatory cleaning process in many institutions, human error and fatigue could hinder the overall effectiveness, risking unnecessary transmission. Hence, it should be augmented with UVC disinfection to ensure complete elimination of pathogens across the premises including all high-touch areas such as tabletops, bedside tabletops, inner drawers, phones, armchairs, doors , cabinet handles, light switches, closet handles, etc.
Capable of 360° disinfection of premises by killing 99.90% of virus and bacteria on surfaces – both airborne and droplet – with the UVC technology.
Quality of disinfection validated by UVC Dose Indicator- a safe and efficient tool calibrated to indicate color changes when exposed to UVC rays. The yellow indicator changes to orange and pink indicating the right levels of accumulated dose sufficient for killing the various categories of pathogens.
Verifying UVC Exposure
The UVC Dose Indicator can be used during each UVC disinfection cycle to help technicians visually validate that surfaces and equipment have received an optimal dose of UVC energy. A color reference chart that demonstrates the changes associated with various energy levels is shown below :
The robot is fully safety compliant. It comes equipped with lasers and PIR Motion Sensors to detect and navigate through obstacles in its path.
A. Detection of overhanging & protruding obstacles.
Overhanging obstacles may damage the UVC lamps and cause mercury leak which is dangerous. The presence of two side lasers help to detect obstacles and the lamp guard provides safety against protruding objects.
B. Detection of human presence and safety against UVC exposure.
UVC light exposure is harmful for human beings. The four pairs of PIR Motion sensors provide 360° detection of human presenceand shut the UVC lights immediately if a human being is around.
LD UVC robot navigates autonomously through a mapped route. It moves seamlessly between irradiation spots thus completely eliminatingthe need for manual labour.
The robot can be easily integrated with third party infrastructures such as elevators, auto doors and PABX systems rendering a complete robotic solution for disinfection needs.
Owing to the extreme flexibility in re-configuring the payloads, the OMRON LD mobile robot base can be utilized for numerous other applications which may arise in the future along with the UVC disinfection needs such as material handling, catering, and varied logistics needs across industries.
