When you see robots in fantasy films, read about them in the news, admire the advanced developments of scientists in this field, these "pieces of iron" still seem to you something unreal, divorced from reality.

However, the Japanese city of Kaso seems to be the robotics capital. The robots of this district of Japan are no more no less like real humanoids, aliens from other worlds. Humanoid robots working side by side with employees in the assembly line at a factory of Glory Ltd., a manufacturer of automatic change dispensers.

Historically, traditional robots have taken humans out of the loop in the workplace replacing employees as a cheaper alternative. But collaborative robots — which are the next wave of machines — are all about enabling humans to do a better job. Rethink Robotics builds these next-gen robots which are created to work alongside humans. They are safe, social, easy to program and eager to learn from humans. Often, workers express concern over whether or not they will be replaced by the machine. But after working with the robot for some time, workers often find that it's actually helped improve their wor.

The only thing that robots lack is the flexibility of thinking and imagination, in other words, fantasy. And, of course, emotions and feelings. But this does not prevent them from working side by side with a man.
