Why have robots been built long ago, but they have not developed greatly so far?

Intelligent robots still have technical obstacles and have little practical value. And the cost is high. Humanoid robots, that is, robots such as robot soccer, robot dancing or Daoxiao Noodles robots. The former is mainly a scientific research project, focusing on research, mainly discussing artificial intelligence and machine learning. The latter is just a stunt, just called a noodle maker, similar to a noodle maker, not a Daoxiao Noodles robot.

In fact, robots have penetrated into all aspects of life, especially manufacturing. It can be said that robots have changed our world. In a broad sense, robots refer to artificial machines and equipment that can automatically perform tasks, replacing or helping people to work. In the past, when Ford made cars, all the workers were on the assembly line. Today's cars are much more complicated than then.

On the contrary, the number of workers in the whole assembly line has been greatly reduced. It can be said that today's cars are made by machines. Foxconn now basically assembles mobile phones by hand, but it is gradually replacing workers with robots. Robots have been fully utilized by electronics factories of many other companies.

It can be said that these electronic devices are made by robots. Needless to say, steel, nuclear energy and chemical industry are all very dangerous workplaces for human beings. Even Ferrari, which boasts that it is hand-made, has to introduce robots into the 599 production line. In order to ensure the machining accuracy of key parts of V 12 engine piston, it is necessary to use liquid nitrogen for special treatment, and then immediately process it. It is difficult to finish the work by hand, so a group of robots are used to finish it.
