Self-Evolutionary Robotic System -Sociobiology and Social Robotics-

This review presents the self-evolutionary robotic system comparing with society of human being, or sociobiology, and robotic system. Since the interaction among individuals evolves the society, the evolutionary robotic system must have the character as a ""society,"" which robotic individuals construct. In this review, we describe the concept of ""social robotics,"" which consists of autonomous distributed robots such as human being or insects, according to its intelligent level. This review shows several topics for realization of self-evolutionary robotic system, such as the comparison between information flow and organization or society of the system, the ability of self-evolution for robotic system from its architecture of control, communication and structure, and comparison between natural gene and technical gene from the theory of natural evolution. In the next generation of robotic system, the ability of self-organization and self-evolution will be desired in any application fields, e.g., manufacturing system, inspection robots, space, agriculture application, and so on.
