  • 本論文的研究目是研發出可以在水中活動的機器人。水中機器人的推進動力來源有許多種,如螺旋槳、水中噴射引擎、仿生(如魚、水母)等許多種方式。本論文使用魚類仿生的方式作為水中機器人的推進系統,並利用防水材料,並配合機構設計與電路整合實現魚型機器人。
    機器人以單晶片(PIC16F877)為控制中心,控制機器人的游泳姿態,變換運動的模式;而遙控器為人機介面,讓使用者可以對機器人下達指令,執行所要求的動作。本論文並探討不同型態的泳姿對魚型機器人所造成的影響,因此實作出兩種不同泳態的魚型機器人,一種為利用尾鰭擺動作為推進的動力來源,另一種則利用胸鰭作為推進的動力來源,且對兩者作比較,探討並分析各自的優缺點。

    The purpose of this thesis is to develop an underwater robot. Underwater robot's propulsive power has many kinds, including propeller, turbine engine, artificial creature-like robot (such as fish, jellyfish), and so on. This study develops a fish-like robot by using the waterproof material, electronic devices, mechanism design and control to fulfill the goal.
    The robot uses a microchip (PIC16F877) as the control center which controls robot's swimming posture, and movement pattern. In addition, by using the remote control as Man-Machine-Interface, a user is able to give the orders to the robot which carries out the movement upon requests. In other words, different swimming postures affect the fish robots which are discussed. Two kinds of different swimming states are developed, one uses the caudal fin swinging as the propulsive power, and the other uses the pectoral fin swinging as propulsive power.
