In this image taken with a remote camera provided by the Florida Keys News Bureau, an ultraviolet light-emitting robot rolls in an active mode in a men's bathroom at Key West International Airport Wednesday, Dec. 9, 2020, in Key West, Fla. Key West is among first airports in the country to take delivery of the apparatus that is programmed to flood areas with UV light to kill COVID-19 and other viruses after initial area mapping. The UV light is so bright that the robot can only be used when people are not present. For the Key West airport, it will supplement other manual disinfecting techniques.
