hello dear @omo-ope

the possibilities of robotics make it very easy to stop the virus, a robot does not get tired, it has no owner and it can be watching that everything is clean 24 hours a day. It also seems super important to me as assistants to people who cannot move or are very old, they can make diagnoses or exams, process them, send the result to the nearest hospital and even request specialists to come in case of detecting any abnormality or emergency.
The nano robot thing is even more fascinating, having an automaton in the body that regulates your temperature and prevents or stops the evolution of these viruses or eliminates them, it is great. Long live science!
