Autonomous robot uses UVC light to kill coronavirus in warehouses

A new robot developed by MIT in the US is being used to kill coronavirus in a 4,000-square-foot warehouse using ultraviolet light (UV) light. The autonomous machine uses a specific type of short-wavelength UV, known as UVC, to kill microorganisms and disrupt their DNA in a process known as'ultraviolet germicidal irradiation'. UVC is emitted from the bot's four vertical beams as it nips around warehouse aisles, killing 90 per cent of coronavirus particles in 30 minutes. Because UVC light is harmful to humans, the robot has to do its work alone and is sent to do its sanitising shift when human workers have clocked off. The robot can map an entire industrial facility – in this case the Great Boston Food Bank (GBFB), a US non-profit that provides hunger relief.
