Scientists at from UCL Mechanical Engineering and UCLH studying how the virus spreads have developed a robot which tracks how droplets move through the air.
In a world first, it’s being used in a London hospital to track how Covid spreads.

It is hoped the robot can be used in theatres and tubes to discover how Covid-19 spreads.
Using a super slo-mo camera scientists will be able to monitor what difference things like ventilation, air conditioning and masks have.
Dr Andrea Ducci tells ITV News: “We create some droplets. The droplets getting out of the mouth of our android and then we look at this plume with a laser we can illuminate the droplets and we have a high-speed camera which eventually will capture the position and then we can capture the images.”
With a mask on “you don’t see much” but remove the mask and it is a different story.
