Prediction Servoing to catch escaping fish using neural network

摘要

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 steady state distance error between the net at robot’s hand and the fish. To overcome the fish’s escaping strategy we propose prediction servoing utilizing estimeted future fish position by on-line adjusting N.N.. The effectiveness have been proven through visual servoing and fish catching experiments.
