1. A robotic device, comprising:
an ultraviolet emission source configured to emit UV light to kill at least one of germs, viruses, and bacteria, the ultraviolet emission source is an attachable module configured to be attached to the robotic device;
and a memory comprising computer-readable instructions stored thereon; and
at least one controller configured to execute the computer-readable instructions to,
disinfect an environment using at least one of an ultraviolet (UV) light or a disinfectant spray;
detect, by at least one sensor, a human being in a path traveled by the robotic device based on sequential images captured by the at least one sensor, the at least one sensor coupled to the robotic device,
predict a path traveled by the human being by the at least one sensor coupled to the robotic device,
avoid directing the ultraviolet light or the disinfectant spray towards the human being by adjusting the UV light or the disinfectant spray if the path traveled by the human being is in the path traveled by the robotic device, and
change behavior of the robotic device upon detection of the attachment of the ultraviolet emission source,
wherein the ultraviolet emission source comprises at least two UV lights, wherein each of the at least two UV lights are configured to emit UV light on either side of the robotic device, the at least two UV lights are configured to disinfect objects adjacent to the robotic device while avoiding the human being.
