Abstract: An automated mobile robot includes a housing, an articulated arm that has at least one UVC light thereon, an actuator that is operable to move the arm between a retracted position and an extended position, a drive unit that is operable to move the housing, a position sensor that is operable to generate position signals indicative of an instant position, a computer, and a battery connected to the actuator, the drive unit, the UVC light, and the computer. The computer is operably coupled to the actuator, the position sensor, the UVC light, and the drive unit. The computer has a predetermined disinfection route and is configured to operate the actuator to move the arm, activate and deactivate the UVC light, and operate the drive unit to move the housing along the predetermined disinfection route based on the instant position and a desired position in the predetermined disinfection route.
