目前水下的推进器几乎都是螺旋桨，本设计将模拟鱼的泳动方式仿生出比螺旋桨更快，更安静的水下推进器。本设计的尾部模块应用了机构简单的以四连杆为基础的摆动机构，同时尾部用韧性材料就能够实现机器鱼的推进运动；尾部的单侧快速摆动能够实现机器鱼的回转运动；活塞缸的吸水和排水功能来实现机器鱼的升潜功能，而且本设计的升潜模块将升潜运动常用的两种方法（变重心位置和改变质量）巧妙的结合在了一起，使升潜模式多样化。本设计通过pro/e仿真软件对研究成果进行仿真验证了设计的可行性。

Abstract This paper introduces a simple design of a new underwater propulsion machinery fish in the new era. Robot technology advances make it possible to develop the underwater propulsion in the 21st century and it has successfully attracted the attention of the elite in various fields. It can be supposed that robotic fish will make it a favorite underwater propulsion sector for high efficiency, low noise, low pollution features.
Currently, almost all of underwater propulsion is made by propeller, this underwater propulsion simulated from the really fish must be swim faster and quieter than it of the propeller. The swing mechanism design of the empennage module to the underwater propulsion based on a simple four-bar linkage mechanism. Advancing movement of robotic fish can be realized with the ductile material fish tail. Fish tail fast swing side of its body to achieve the rotary movement of machine fish. Piston cylinder absorb and exhaust water to achieve the rise and descend movement and the design of the rise and descend module ingenious combine two commonly methods (change the center of gravity or changing quality)together to make the mode persification. Here research results of the feasibility of the design by pro / e simulation software.
Keywords: Intelligent robotic fish; efficiency; four bar linkage; up and down module; simulation
