Science fiction writes wrote about rockets to the moon, nuclear power, the Internet and robots. All of these things are now a reality, except for the robots.

Some robots can perform a single task such as vacuuming the carpets or moving the lawn, but they don’t have the power of reasoning and scientists simply don't know how to give robots this ability. Researchers say that the best way to overcome this problem is to study the human brain and create an artificial brain that copies its functions.

Nevertheless, scientists have already overcome other problems such as mobility. For example, Honda's ASIMO robot can walk, run and climb stairs without any problems. Also, robots can now look more human.

All in all, experts are divided as to when robot assistants may become a reality. Who knows - soon household robots may be as common as home computers.
