Can Autonomous UV Disinfection Robots Sterilize a Room? A Review

ABSTRACT

The coronavirus disease 2019 pandemic has forced us to improve hygiene. Sterilizers have been widely used in public and private homes. Ultraviolet (UV) robots with different designs, biological interactions, and features have been widely used as sterilizers. The dose issued is only based on theoretical calculations under optimal conditions without considering other environmental factors. This ideal condition is unsuitable to apply in real conditions. Factors such as room temperature and room airflow could affect the effectiveness of UV sterilizers. This review aims to propose an ideal design for UV sterilizer robot by adding a feedback system to minimize external disturbances. The development of UV robots is necessary for future design improvements to be effective and efficient. © 2022 UPM Press. All rights reserved.
