The new tracking control system has been developed for Free-Space Optical Communications. It consists of the agile two-axis gimbals, the high performance fine-pointing-mechanism, the optical coarse acquisition sensor, and the optical fine tracking sensor. In the conventional tracking control systems, the two-axis gimbals is combined with the narrow range actuator for the fine pointing control, and...
One of the most amazing phenomena widely observed in nature is self-assembly; living systems spontaneously form their body structure through the developmental process. While this remarkable phenomenon are not thoroughly understood in biology, the concept of self-assembly becomes undeniably indispensable also in artificial systems as they increase in size and complexity. Based on this consideration,...
One of the most graceful phenomena widely observed in nature is self-assembly: living systems spontaneously assemble their body structure through the developmental process. Because of this case, we believe that the concept of self-assembly becomes undeniably indispensable in artificial systems as they increase in size and complexity. Based on this consideration, we intend to deal with the emergent...

This paper discusses a fully decentralized algorithm able to control the morphology of a modular robot, consisting of many identical modules, according to the environment encountered. One of the significant features of our approach is that we explicitly exploit an "emergent phenomenon" stemming from the interaction between control and mechanical dynamics in order to control the morphology...
