We all need robots. As you know already, robots can help humans a lot.
They can move heavy stuff so easily instead of humans. And They can save people in danger. They can go into fire, broken building, flood area. We just order them to go. then they go ~
I am going to give you another example.
Nowadays, the number of family member is getting decreased. and the number of getting married is also decreased. It means people feel more lonely than ever. In this situation, robot can be good solution for them.
