Relative Evaluation of Robot and Fish Intelligence in Antagonistic Relationship: -Fish Catching Operation by Robot Using Plural Chaos-@@@―カオスを用いたロボットによる魚捕獲実験―

In this paper, we report relative comparison on leaning speed of fish in an antagonistic relationship of prey and predator—the prey is fish and the predator is a robot seeking to catch fishes by a net attached robot’s hand by means of visual servoing. It was confirmed that the fishes have found escaping strategy by itself. The effectiveness of the conceived escaping strategies by fish has been measured as learning speed that describe decreasing tendency of how many fish could be caught in constant time when the fish caught be released immediately to the same pool. To overcome such fish’s ability to conceive new strategies for escape, chaos have been added to the net motion and the effectiveness of chaos are experimentally examined. In this report, using other three chaoses in the operation and comparing catching results, the effectiveness of chaos is examined.
