Abstract
Several room disinfection robots using Ultraviolet C (UV-C)
light have emerged recently, especially with the COVID-19 outbreak. This
systematic review aims to identify the current development status of
Ultraviolet Germicidal Irradiation (UVGI) disinfection robots, their
limitations, and the technologies they use. An automated search was
performed on the Scopus, ACM Digital Library, IEEE Xplore, and
SpringerLink platforms for papers up to July 2023, followed by a
snowballing search. Were found 96 studies, of which the majority were
not concerned with the dose of UVGI applied or did not implement any
technique to deliver the appropriate dose; the positioning of the lamps
was carried out subjectively; and most of the works did not implement
any technique to prevent accidents with UVGI. From the analysis of these
studies, it was possible to propose a novel classification for the
different types of robots based on their technological and readiness
levels. The data shows that despite recent advances, the development of
disinfection robots is still early, with many advances to be made.
