232 Conclusions
In the experiment, a robot equipped with the consciousness
system is placed in front of a mirror. The experiment starts
as the robot moves forward or backward. The robot repeats
moving forward and backward in front of the mirror during the
experiment. LED colored lamps mounted on the robot indicate
the representation occurring within the robot to allow observation
externally. The LED lamps go on each time the robot moves. When
the lamp goes on, the robot is also measuring the coincidence of
behavior between the self and other robots. The coincidence rate
was 70% in this experiment.
In another experiment, the mirror was removed and instead a
physically nearly identical robot (the same model of robot) was
placed in the same position. The second robot is connected to the
first one by control cables. The first robot is equipped with the
consciousness system, and the second one incorporates a simple
reflex program to perform the behavior commanded by the first
robot. The first robot transmits its behavior to the second robot to
have it perform the same behavior. Both robots repeat forward and
backward motions, generally much like the first experiment in front
of the mirror. The coincidence rate was 60% in this experiment.
The experiments were repeated many times but the differences
were nearly the same. The order did not change either. Robots of
other makes were used in the experiment. The coincidence rates
were different but the order did not change.
From the results of these experiments, and considering the fact
that the second robot is wired to, and moves as commanded by, the
first robot, we can conclude that the second robot is a part of the first
robot.
The robot in the mirror in the first experiment has a higher
coincidence rate (70%) than the robot that is part of the self in
the second experiment (60%). We therefore conclude that the robot
in the mirror (i.e., the self image) is an existence closer to the self
than a part of the self. This conclusion will surely provide a clue to
solving the several-thousand-year-old mystery of “why is the image
of the self in a mirror felt to be the image of the self?”It will also be
the first step toward solving the mechanism of humans becoming
aware of the existence and thought of the self and the external
world.

Conclusions 233
The neural networks I named MoNAD do not perfectly represent
human consciousness but can describe the phenomena of human
consciousness rather well. The robot equipped with the MoNAD
program succeeded in the mirror image cognition test, and this was
the world’s first success of its kind. As such, it can be said that the
world’s first conscious robot was created.
My dream is for readers to further develop the MoNAD theory
to facilitate the establishment of an age in which conscious robots
equipped with functions similar to human consciousness will help
create a better world together with humans. I also hope that the
MoNAD will be actively used to understand the human brain and
contribute to the diagnosis and treatment of brain diseases. If this
is successful, I believe that there is a promise of a bright future for
humankind. I will put down my pen while sending hearty greetings
to the readers.
