RE: A robot is a machine made with metals to assist and not to replace humans.

Really robots cannot replace humans because they function according to our institutions.
They are made of metal that has no feelings.
I see no difference from a robot and a car packed.
The difference is that it has not been engaged, so all it's life it depends on us, even the charging requires human effort.
For me, it's not wise to say an iron put together is better than a being.
If humans were made in God's image and likeness, then how will a robot be more better than a human.
