I think the idea of a robot healing a COVID-19 patient is pretty useless. I say that because it is completely unreasonable for every patient to have a robot at their side because it would cost billions of dollars. There are many things that can go wrong with this invention. For example if it was not effective, but was in mass production, it would be a waste of money. Another example is even if it did work, I doubt the country can have one robot for the ever increasing amount of COVID-19 patients. Another risk these robots have is their use of UV Radiation. Just find a vaccine for the love of God.
