9.Summary of Research Results

 Based on system theoretical analyses of the roles of information on life systems, novel methodologies of synthesizing decentralized (modularized) artifact systems that have high capabilities of adaptation and coordination of interactions with humans and environments have been developed. We focused our attentions to the emergent characteristics in interactions between : (1) artifact systems and humans, (2) robots and humans, (3) robots and environments, together with, (4) the total coordination of the above interactions. The mechanisms of order emergence have been examined through introducing an intelligent human judgmental model, an integrated simulation framework for human-machine interaction, semiotical and ecological psychological approaches to human-robot interaction, a modularlized control architecture for autonomous locomotion robot, and order emergence mechanisms in dual dynamical systems (coupled nonlinear dynamical systems). The followings are the main results of our project: A sophisticated artificial creature in a virtual space, "virtual collaborator", mediating human operators and artifacts, human-robot shared autonomy frameworks, robot teleoperation systems using task morphologies, a highly adaptive legged locomotion robot. Through synthesizing the above architectures with physiological, psychological, semiotical and mathematical frameworks, we have found out that life-like systems are necessarily of hierarchical structures composed of redundant modules that are loosely coupled with each other where "functional complementarity" such as autonomy vs. sociality, stability vs. plasticity, differentiation vs. integration, and order formation vs. order destruction plays important roles in the vital functioning of information in these systems.
