The Korea Institute of Machinery and Materials has created a smart robot for infectious disease prevention that estimates virus spread in indoor spaces using artificial intelligence.
The AI robot is able to map out its own disinfection path in real-time. Through a probability mapping algorithm, it estimates where viruses are mostly concentrated based on CCTV data of the number of people in an enclosed area and their length of stay.
Then, it goes along its calculated path and sprays clean air sterilised by ultraviolet radiation, instead of the usual UV-C sterilisation lamps which can be harmful to humans. It can fumigate seats and air even if people are around.
