摘 要
本文簡(jiǎn)要介紹了機(jī)器人的概念，機(jī)械手的組成和分類(lèi)，機(jī)械手的自由度和坐標(biāo)形式，氣動(dòng)技術(shù)的特點(diǎn)，PLC控制的特點(diǎn)及國(guó)內(nèi)外的發(fā)展?fàn)顩r。
本文對(duì)機(jī)械手進(jìn)行總體方案設(shè)計(jì)，確定了機(jī)械手的坐標(biāo)形式和自由度，確定了機(jī)械手的技術(shù)參數(shù)。同時(shí)，計(jì)算并設(shè)計(jì)出了回轉(zhuǎn)氣缸、伸縮手臂的機(jī)械機(jī)構(gòu)。
設(shè)計(jì)出了機(jī)械手的氣動(dòng)系統(tǒng)，繪制了機(jī)械手氣壓系統(tǒng)工作原理圖，對(duì)氣壓系統(tǒng)工作原理圖的參數(shù)化繪制進(jìn)行了研究，大大提高了繪圖效率和圖紙質(zhì)量。
利用可編程序控制器對(duì)機(jī)械手進(jìn)行控制，根據(jù)機(jī)械手的工作流程制定了可編程序控制器的控制方案，設(shè)計(jì)出了人工移動(dòng)式（無(wú)動(dòng)力）點(diǎn)位示教控制軟件，并畫(huà)出了機(jī)械手的工作時(shí)序圖，并繪制了可編程序控制器的控制程序。

Abstract
At first, the paper introduces the conception of the industrial robot and the eler. dary information of the development briefly . What’s more, the paper accounts for the background and the primary mission of the topic.
The paper introduces the function, composing and classification of the manipulator , tells out the free-degree and the form of coordinate . At the same time, the paper gives out the primary specification parameter of this manipulator,
The paper designs the structure of the hand and the equipment of the drive of the manipulator ,
This paper designs the structure of the wrist , computes the needed moment of the drive when the wrist wheels and the moment of the drive of the pump.
The paper designs the structure of the arm.
The paper designs the system of air pressure drive and draws the work principle chart , the manipulator uses PLC to control . The paper institutes two control schemes of PLC according to the work flow of the manipulator . The paper draws out the work time sequence chart and the trapezia chart . What’s more , the paper workout the control program of the PLC ,
