Can "brains" be manufactured?

I was searching for technology and applications with "artificial intelligence" and discovered the ASIMO (Advanced Step in Innovative Mobility). It first attracted my attention because I remember watching the South Park show where Cartman dressed up as the "Awesome-o- 2000", which was a hilarious episode. However, in reality the ASIMO is a humanoid robot developed in 2002 by the Honda Motor Co. and was debued in February for its artificial intelligence capabilities and advanced human interaction. ASIMO can run on smooth and rough surfaces up to 4 mph, maneuver a cart using pressure sensors on its wrists, including changing direction and speed control, and it can climb stairs. However, the artificial intelligence factor in this robot lies in its capability to interact with its environment through visual sensors. It has sensors all over its body, including camera sensor in its head that allows it to receive and hand objects to humans as well as walk alongside a human with syncronized motion, much like two best friends taking a walk together.
The one thing that the ASIMO is missing is reasoning and a level of understanding. This is where AI is trying to develop machines on the basis of a "frame" understanding. A frame can be defined as a common situation, such as sitting in a living room with your family. Within a certain frame there will be associated reactions, knowledge and behavior that the machine can utilize to communicate properly. This is similar to humanity's frame of social etiquette. We yell and scream at basketball games, but in the classroom we are quiet. Everything is connected by a visual realization through a sensor (eyes) and a link to the knowledge about that situation (brain). From this perspective, i believe we are well on our way to discovering the manufactured brain. Of course, this gets way more complicated, but this is a sensible beginning toward the development of artificial logic.
