Fish-catching by Robot Using Prediction Neural Network

This paper presents a method to predict a fish motion by Neural Network(N.N.) with on-line learning when a robot is pursuing fish-catching by a net at hand through hand-eye robot visual servoing. We have learned by previous experiments that fish is much smarter than a robot controlled by visual servoing whose escaping strategy is to make a steadytate distance error between thenetat robot’s hand and the fish. To over come the fish’s escaping strategy we propose prediction servoing utilizing estimated future fish position by on-line adjusting N.N.. The effectiveness have been proven through visual servoing and fish catching experiments.
