以遙控玩具店，市售標準的遙控伺服機來做實驗，此一裝置在無線電遙控飛機、遙控船上一定會用到，主要是介紹其內部結構及工作原理，並以8051 介面來設計驅動程式，可以精確的控制伺服機動作。了解其工作原理後還可以有其他的應用，凡是需要拉動或是做簡易的機械式傳動機構設計，都可能有機會使用到它。對於非機械本科系的同學，只要懂得 8051 介面設計，也可以很有效率的設計一些精密的傳動系統，這完全拜伺服機之賜，讓我們可以簡單的電路完成複雜的控制系統整合設計。-The remote control toy, remote control standard commercially available servo to experiment, this radio-controlled device in the aircraft, remote control boat will be used mainly their internal structure and working principle, and 8051 interface design driver , can accurately control the servo action. After understanding how it works can also have other applications, all need to pull or do simple mechanical transmission design, may have the opportunity to use it. Non-mechanical system for undergraduate students, as long as 8051 to understand interface design can also be very efficient to design sophisticated drive system, it is entirely thanks to servo to give the circuit so that we can simply integrate complex control systems design.
