The problem with many droids is the amount of processor power
required for actions that most humans can accomplish without any
difficultly. A smooth walking gait, free and easy motion of the
upper body, and the catching of light projectiles are all actions
that take huge amounts of processor power. Gyrien Zorag, dictator
of the Legal Empire on Mithros-B
suggested a novel solution to that problem. By using a human
cerebellum (the part of the brain that controls actions of that
type) in the brain circuitry of the droid, you would have a droid
with a top of the line reflex center that takes up a fraction of
the space that a mechanical reflex center requires.
The C-4 Multi-purpose droid was the Legal Empire's first
attempt at a droid of that type. However, some problems developed.
First of all, the droids experienced some of the effects of an
implanted human subconscious, suffering from hallucinations when
not allowed some rest with the brain unit activated. Second of
all, even the very sophisticated med droids of Legal were not able
to transfer the cerebellum successfully every time. In fact, they
only succeeded every third operation, losing two out of three
slaves completely. These problems might have been solved were it
not for the fact that the C-Factor project was prematurely shut
down, when three transports, each containing almost a hundred
thousand slaves were destroyed by the Accdept hegeonomy, and
Legal's slave trading partner put Mithros-B off limits.
Of the first few runs of C-Factor droids, a few survive. More
independently minded than other droids, they also don't move like
droids, and can pass as humans if not investigated too closely.
Those that have escaped the killing fields of Mithros can be found
throughout the galaxy, trying to escape the fragmentary human
memories that they got together with their cerebellums.
