Hi Eri, (at least I post something... :)
As a new member, I would like to give some explanation from www.answers.com
Hope this work for all of us....
A positronic brain is a fictional technological device, originally conceived
by science fiction writer Isaac Asimov. Its role is to serve as a central
computer for a robot, and, in some unspecified way, to provide it with a form
of consciousness recognisable to humans. When Asimov wrote his first robot
stories in 1939/1940, the positron was a newly discovered particle and so the
buzz word positronic, coined by analogy with electronic, added a contemporary
gloss of popular science to the concept.
Asimov remained vague about the technical details except to assert that the
brain's substructure was formed from an alloy of platinum and iridium. Asimov
relied on the reader's knowledge of the capacity of positrons and electrons to
be formed in pairs and to annihilate each other, in order to convey the
impression that such pair creation and destruction could serve as a metaphor
for the evanescence of thought. The focus of Asimov's stories was directed more
towards the software of robots (such as the Three Laws of Robotics) than the
hardware in which it was implemented.
Several robot stories have been written by other authors following Asimov's
death. For example, in Roger MacBride Allen's Caliban trilogy, a Spacer
roboticist called Gubber Anshaw invented the gravitonic brain. It offered speed
and capacity improvements over traditional positronic designs, but the strong
influence of tradition made robotics labs reject Anshaw's work. Only one
roboticist, Fredda Leving, chose to adopt gravitonics, because it offered her a
blank slate on which she could explore alternatives to the Three Laws. Because
they were not dependent upon centuries of earlier research, gravitonic brains
could be programmed with the standard Laws, variations of the Laws, or even
empty pathways which specify no Laws at all.
I, Robot, 2004 Film The robots in the 2004 film I, Robot also had positronic
brains. Sonny, one of the main characters from the film, had two separate
positronic brains working in unison (The second being a positronic "heart"),
which meant he had choices open to him the other standard robots in the film
did not. He also had the possibility of being able to develop emotion.
Additionally, there was a colossal positronic brain, VIKI, that played a
prominent role in the story.
Bicentennial Man Spoiler warning: Plot and/or ending details follow.
The robots in the 1999 film Bicentennial Man (based on one of Asimov's
stories) also had positronic brains, including the main character Andrew, an
NDR series robot that started to experience human characteristics such as
creativity. Only when Andrew allows his positronic brain to "decay", thereby
willfully abandoning his immortality, is he declared a human being. This event
takes place on the two-hundredth anniversary of his creation, hence the title.

Hi all,
Lt. B'lana Tores dalam episode "Prototype" di Voyager S2 mengatakan bahwa,
hanya ada satu AI yand murni robotic (tanpa campuran organic sama sekali)
yang hidup di antara manusia dan dianggap sejajar derajatnya dengan manusia,
yaitu "Data".
Dari sana saya menyimpulkan bahwa di zaman ST nantinya hanya ada satu AI
yang berhasil secara cemerlang mendapat tempat yang paling baik di antara
manusia, dia adalah Data.
Jika arah pengembangan AI (dalam dunia nyata ini) akan ke arah sana (Data),
maka satu hal yang membuat Data unique adalah "Positronic Brain" -nya. Yang
tidak bisa ditiru oleh siapa pun di Galaxy ini.
Jadi, saya menyimpulkan bahwa Positronic Brain itulah kunci dari kemuliaan
Data.
Nah, saya penasaran sekali nih.
Pertanyaan saya, Adakah yang bisa jelaskan apakah itu Positronic Brain?
Salam,
Eri
