Singapore uses UV robot to exterminate corona virus in mall

A shopping mall in Singapore is now using a robot to sterilize the mall and to make it saver in the fight against the corona virus. The robot uses no chemicals but UV light. This way even hard to reach crevices are being cleaned. The UVC robot also cleans the air by killing germs and viruses floating around. Although the light is harmful for people, the robot is programmed in such a way that if it detects a human in proximity it turns of its lights.
