So its a robot made to stomp on roaches?

. People I think it is possible
. An artificial brain to be made and rest is simple

. It is assumed that the brain is very complex, but according to me it is not such a difficult device to be made, the heart is just a pump.
What does the brain do, what comes to my mind is:

1) By its senses perceives the environment and reacts according to its knowledge
2) Regulates functions of the human body organs3)Process the information it has
3) Processes the information it has
4) Collects information by its senses
5) Remembers
The available technologies, I think, already are capable of achieving this.
I am not a programmer, an electric engineer or a medic, or any other profession, just like other people
Collect and associate things
It will not be a robot, just healthy and immortal 
I hope I have not wrote many fantastic things
