Robot greeter fights coronavirus in South Korea

There's an new, high-tech greeter at the lobby of SK Telecom in Seoul, South Korea. It checks body temperatures, dispenses hand sanitiser, disinfects the floor and can see who is and isn't wearing a mask -- an AI-driven helper in the fight against COVID-19. SK employee Lim Yeon-June said she's realised how useful it can be. 'At first, I felt awkward when I heard it was a robot doing this. But when my colleagues and I were talking to each other, the robot said 'please move away from each other for social distance', I found myself walking away and it was really impressive.'
