Abstract
Implementations of the disclosed subject matter provide a device of a mobile robot may include a motor to drive a drive system to move the mobile robot in an area, and a light source to output ultraviolet light. The device may include at least one first sensor to determine at least one of an orientation of the mobile robot, a location of the mobile robot, and/or when the light source is within a predetermined distance of an object in the area. The device may include a controller, communicatively coupled to the drive system, the light source, and the at least one first sensor to control the drive system so as to stop or move the mobile robot before the light source is within the predetermined distance of the object based on at least a signal received from the at least one first sensor.
