Robot Dogs Evolve Unique Personalities
     

A
Phsyorg story
details research at the
KAIST Robot Intelligence Lab in which scientists use evolutionary
processes to develop unique personalities for simulated robots. Their
first robot dog, known as Rity, has 14 chromosomes with a total of 1,746
genes that affect the dog's personality and interactions with its
environment. The
evolutionary processes can go through 3,000 generations every 12 hours,
narrowing in on a personality which best fits one of two desired
behaviors described as
either agreeable or antagonistic. For comparison, researchers used both
manual and random processes to generate genomes but neither could match
the results achieved through the evolutionary process. The next steps
are to improve and generalize the genome structures to allow their use
in other types of robots. All the technical details can be found in the
paper, Evolutionary
Generative Process for an Artificial Creature's Personality (PDF
format) from the May issue of IEEE Transactions on System, Man, and
Cybernetics.
