This project aimed at(1) Visual Observer-Based Cooperative Control,(2) Cooperative Task Switching Algorithm Design,(3) Robust Cooperative Control Algorithm Design,(4) Establishment of a Robotic Sensor Network System. On Topic(1): We succeeded in deriving theoretical results on conditions for achieving successful cooperation. The result was accepted for presentation at premier conferences, where it received a high evaluation as the first paper providing a nonlinear observer-based cooperative control scheme with theoretical guarantees. The result was also published in a domestic journal. We also extended the result from a pin-hole type camera model to a panoramic camera model so as to overcome the view angle issue which is an essential problem when we use a vision sensor. The result was also published in an international conference and a domestic journal. On Topic(2): We have succeeded in presenting a task switching law based on a so-called consensus protocol. The paper received a best presentation award at a premier conference. Moreover, we presented another distributed task switching algorithm based on evolutionary game theory, which was published in an international journal. On Topic(3): We thought of an idea that robust cooperation is met by integrating game theory with cooperative control. As a preliminary, we first addressed the problem in(i) via game theoretic approach, which was successfully accepted for an international conference and a domestic journal. Moreover, we presented a learning algorithm leading agents to the optimal actions even without any prior knowledge on environment. A series of the results will be presented at a conference and, recently, the journal version was accepted for publication. On Topic(iv): We succeeded in establishing a robotic sensor network system and most of the papers mentioned above include experimental verification using the system.
