摘要:人類已經(jīng)走過了數(shù)個世紀，我們從原始社會邁入了現(xiàn)在的智能高科技社會。人們以前從事任何生產(chǎn)可能都需要自己親自動手或者是借助于某些工具間接的生產(chǎn)工作，但隨著社會的快速高科技發(fā)展，隨著教學智能機器人的橫空出世，我們再也不需要用自己親自去做某項工作，從而不用在花費大量的時間在其上面，我們有時只需要一句話或者一個手勢，也可能是一個眼神等等，我們就能讓智能機器人去代替我們?nèi)氖履臣虑椤５珡氖陆虒W型機器人的開發(fā)是一件具有挑戰(zhàn)性的任務(wù)，因為它包含了機器人的軟硬件設(shè)計和電路設(shè)計等等內(nèi)容，是當今國內(nèi)外專家共同研究的重要項目之一。

教育型機器人的概念非常抽象難懂的，在這次的設(shè)計研究中我準備在避障功能中在加以聲控系統(tǒng)，從而使其具有避障和聲控的雙功能，實際上就是一個聲控啟停避障機器人的設(shè)計。在硬件設(shè)計方面我使用STC89C52單片機作為該設(shè)計機器人的核心控制器，它是機器人的心臟，是機器人的靈魂，任何信號都要通過它才能使機器人做出相應(yīng)的動作反饋，任何傳感器只有借助于它才能正常工作。3個紅外線傳感器用于接收路面情況信號，不斷的把接收到的信號傳給STC89C52單片機，以便其做出相應(yīng)的動作反饋，同時傳感器的測距最遠可達到80cm，完全符合我的設(shè)計需要。在驅(qū)動電機模塊方面采用了L298N驅(qū)動電路，它是一個非常簡單的驅(qū)動電路，它通過接收單片機反饋給它的信號，從而做出相應(yīng)的動作。聲控啟停模塊采用了YL-56 聲控傳感器，YL-56可以檢測周圍環(huán)境的聲音強度，也可以識別和檢測聲音的有無（根據(jù)震動原理檢測），但它不能識別聲音的強弱或者特定頻率的聲音，也就是不能識別一句語言，所以把YL-56作為聲控啟停開關(guān)是非常合適的。總體來說該設(shè)計就是具有聲控加避障功能的聲控啟停避障智能機器人。

ABSTRACT:Mankind has gone through several centuries, from the primitive society has entered a smart tech society. Previously engaged in any production may need their own hands or by means of indirect production work for some of the tools, but With the rapid development of high technology, as teaching intelligent robots turned out, we no longer need to use their own person to do a particular job, and thus do not need to spend a lot of time in the above, we sometimes need only a word or a gesture, a look, and so on, we can make intelligent robot to replace us to engage in something. Engaged in the development of teaching robot is a challenging task, because it contains the robot's hardware and software design and circuit design, is one of the important projects of today's domestic and foreign experts to study .

　　　Educational robot concept is very abstract and difficult, in the design of this study, I am ready to be voice-activated system in obstacle avoidance capabilities in obstacle avoidance and voice function, so that it has, in fact, a voice start and stop to avoiddesign impaired robots. STC89C52 microcontroller hardware design as the core of the design of robot controller, which is the heart of the robot, the robot soul, any signal to go through it in order to make the robot to make the appropriate action feedback, any sensor only by means of which to work properly. Three infrared sensor for receiving road conditions signal, the received signal to STC89C52 microcontroller in order to make the appropriate action feedback, the sensor ranging as far as up to 80cm, fully in line with my designs. L298N drive motor module with a driving circuit, it is a very simple drive circuit, the feedback signal to it by the receiving microcontroller, to make the appropriate action. The voice start-stop module using the YL-56 voice sensor . YL-56 can detect the sound intensity of the surrounding environment, can also identify and detect the presence or absence (detected) according to the vibration principle of sound, but it does not recognize the strength of the sound or specific frequency voice, which does not recognize a language, so the YL-56 as a voice off switch is very appropriate. Overall, the design is a voice plus obstacle avoidance voice start and stop intelligent robot obstacle avoidance .
