Abstract

Humans normally feel physical and mental pain. In this paper, we refer to physical pain as "pain in the body" and mental pain as "pain in the mind". We took an interest in the mechanism that makes a robot feel such pain in its mind and act appropriately to the sensation of pain. We developed a neural network program called MoNAD that can explain almost all of the phenomena of human consciousness. We noted that the program outputed stable information on what had been learned but became unstable when unknown information was inputed or a system error occurred. We thought that we could create "pain in the mind" of robot by making use of this phenomenon. This paper proposes a demonstration of "pain in the mind" in robot. We expect that this research will also lead to a deeper understanding of humans.
