Nano-robot is a very small thing, so small that we can't see it without looking carefully. It can enter human blood vessels for minimally invasive surgery. It can have its own exploration function and its own cleaning function. Perhaps its function is very simple, but because it is very small, it will not cause great harm to human body, so it is widely used in medical surgery or corresponding operations such as vascular brain. These robots will be more accurate and much better than human hands.
Of course, there are other applications, such as in the field of military exploration. In some very narrow terrain, people can't get in, and traditional detection methods can't get in. What should we do at this time? Then use nano-robots to enter this place. Of course, the so-called nano-robots are not really smaller than nano-robots, just that they are very small, and we can use them to carry out a series of activities in tiny terrain and tiny space. Being able to really make good use of this thing will be of great help to our scientific and technological development and our exploration of the unknown world.
It is not so exaggerated to change people's lives, because changing people's lives is to change some people's lives, not all people's lives, and we rarely touch them in our daily lives, because this kind of thing is still a high-tech product after all, and its design, maintenance and operation are very technical activities, which require a lot of economic support. We don't usually use much, and most people don't have the financial ability, so it won't have much impact on the lives of ordinary people.
