We live in the 21st century and the phenomenon of robots in our lives, we are familiar and not a wonder. If earlier, 50 years ago, robots were something supernatural, and notes about them could be read only on the pages of science fiction books and magazines, now robots are not news, and are found everywhere. For example, a washing machine-the same robot programmed to wash our clothes, or player – also works, a computer robot! Indeed, more and more new technologies are coming up with people to make their lives easier, and call them robots. But what are robots and how do they affect our lives?
We will not go into technical details, but note that the robot is an automatic device created on the principle of a living organism, programmed for a particular action. Moreover, the robot can perform the action, as receiving commands from a person, and not receiving.
On the one hand, the robot in our time is a very useful thing, it is thanks to them, people make their lives easier. Take a simple example, computational robotics. It is not necessary for 9-10 hours a day to suffer, trying to calculate a particular task, citing certain arguments, sweating over the papers, and as a result zero. Now we have robots that just need to be programmed to solve the problem, set all the variables, and they will calculate the answer.  If you imagine all this in a simplified way, it is akin to a calculator – you enter the data, and for you all do. Robots often perform difficult or even impossible tasks for humans.
