COVID-19 pandemic is a serious situation around the world. People have concerned about some viruses spreading in public areas. To restrain the spreading of the virus, a solution to the virus disinfection has been performed by chemical solutions and some thermal processes. The ultraviolet-C light is a non-consumable disinfection method that can disinfect the virus by the sufficiently UV-C does. Therefore, the sterilizing process should be able closely to access through the target area for avoiding insufficient UV-C does. This research has the objective of introducing an automatic UV-C disinfection with the AGVCobot system service for the COVID-19 pendemic. AGV was employed for running on the scheduled routing by programming or real-time IoTs remoting. Cobot has a controllable human-motion function to provide the UV-C lamp closely scan on the target surface with an object recognized machine vision. The invention unit was tested for verifying the scanning parameter that has the capability for killing some mock-up virus in the patient’s room in hospital. From the experiment, the virus was perfectly killed at 3-log reduction with a UVC to-surface distance of 1 cm and a velocity of 1 cm/s. With this needed speed and base on the experiment results, sterilize the standard patient's room that has an area approximately 32 m2 in the hospital by AGV-Cobot with UV-C disinfection can be able in under 40 minutes. Meanwhile, the scanning time that emitting UV-C light to all furniture in the patient's room is under 25 minutes which has utility approximately 71.43% without any residues without any residues.
