Fab Lab Bahrain’s new COVID-fighting robot uses UV light to disinfect

The smart device, a prototype by Fab Lab Bahrain, uses UV-C light that kills or inactivates a range of microorganisms by disrupting their DNA or RNA.

A “coronavirus-fighting” robot that has the ability to work autonomously around public spaces has been unveiled in Bahrain.

Designed by Fab Lab Bahrain – in collaboration with the country’s Ministry of Youth and Sports Innovation Centre – the machine uses ultraviolet germicidal irradiation (UVGI) to disinfect commonly used areas, such as an office space, for example.

The machine was tested within an industrial facility where it ran a UV sanitation cycle around the premise of the facility.

UVGI is a known disinfection method that utilizes short-wavelength ultraviolet C (UV-C) light to kill or inactivate a range of microorganisms by disrupting their DNA or RNA. This leaves them unable to perform vital cellular functions. Coronaviruses are enveloped, single-stranded RNA viruses.

UVGI is commonly used in water treatment and air purification. However, due to the fact that UV-C can irritate eyes and skin, the technology is only for use in unoccupied areas.
