A　novel　fish-like　flexible　micro-robot　actuated　by　ICPF　(Ionic　Conducting　Polymer　Film)　is　presented　in　the　paper.　In　order　to　improve　the　controlling　reliability　and　feasibility　of　the　robot＇s　movement,　we　establish　the　dynamic　model　of　the　micro-robot　by　applying　kutta-joukowski　theorem　and　illuminate　the　nonlinear　characteristics　on　a　y　direction　phase　and　displacement　of　the　robot＇s　movement.　Some　simulation　and　experiment　graphs　about　the　y　direction　phase　and　displacement　of　the　robot　are　performed.
