A robot walks on four legs.It stops in front of a chair，and a mist（霧氣）comes out of its head.The robot turns itself to the left，then to the right，then up and down.There is always germ（病菌）in our house.The robot is using it to clean germ on the chair.After that，the robot will move on to the next one.
"Named LASER-D，it's a robot dog，" said Yiyu Chen，one of its designers（設(shè)計者）.His team already tested LASER-D in different places.Chen hopes that in the future the robot will know other things on its own and find out how to clean each side of a thing.The team also wants to give LASER-D an arm so that it can open doors or move things.
At the University of Virginia，some people are testing another robot.This one，DINGO，looks more like a giraffe.It cleans things with ultraviolet light（紫外線）.The light comes out from the sides and bottom（底部）of the robot.At the same time，its neck turns around，sending out more light onto the chairs，desks and other things in a room.
Of course，people can disinfect（消毒）rooms as well，but this job is dangerous.Because of COVID-19，so many places need to be cleaned，but there may not be enough people to get the job done.Maybe people need more robots to do the work over and over again without getting tired.
