This article introduces ATR's "CAM-Brain Machine" (CBM), an FPGA based piec
e of hardware which implements a genetic algorithm (GA) to evolve a cellula
r automata (CA) based neural network circuit module, of approximately 1,000
neurons, in about a second, i.e. a complete run of a GA, with 10,000 s of
circuit growths and performance evaluations. Up to 65,000 of these modules,
each of which is evolved with a humanly specified function, can be downloa
ded into a large RAM space, and interconnected according to humanly specifi
ed artificial brain architectures. This RAM, containing an artificial brain
with up to 75 million neurons, is then updated by the CBM at a rate of 130
billion CA cells per second. Such speeds should enable real time control o
f robots and hopefully the birth of a new research field that we call "brai
n building". The first such artificial brain, to be built by ATR starting i
n 2000, will be used to control the behaviors of a life sized robot kitten
called "Robokoneko".
