摘要:人类已经走过了数个世纪，我们从原始社会迈入了现在的智能高科技社会。人们以前从事任何生产可能都需要自己亲自动手或者是借助于某些工具间接的生产工作，但随着社会的快速高科技发展，随着教学智能机器人的横空出世，我们再也不需要用自己亲自去做某项工作，从而不用在花费大量的时间在其上面，我们有时只需要一句话或者一个手势，也可能是一个眼神等等，我们就能让智能机器人去代替我们去从事某件事情。但从事教学型机器人的开发是一件具有挑战性的任务，因为它包含了机器人的软硬件设计和电路设计等等内容，是当今国内外专家共同研究的重要项目之一。

教育型机器人的概念非常抽象难懂的，在这次的设计研究中我准备在避障功能中在加以声控系统，从而使其具有避障和声控的双功能，实际上就是一个声控启停避障机器人的设计。在硬件设计方面我使用STC89C52单片机作为该设计机器人的核心控制器，它是机器人的心脏，是机器人的灵魂，任何信号都要通过它才能使机器人做出相应的动作反馈，任何传感器只有借助于它才能正常工作。3个红外线传感器用于接收路面情况信号，不断的把接收到的信号传给STC89C52单片机，以便其做出相应的动作反馈，同时传感器的测距最远可达到80cm，完全符合我的设计需要。在驱动电机模块方面采用了L298N驱动电路，它是一个非常简单的驱动电路，它通过接收单片机反馈给它的信号，从而做出相应的动作。声控启停模块采用了YL-56 声控传感器，YL-56可以检测周围环境的声音强度，也可以识别和检测声音的有无（根据震动原理检测），但它不能识别声音的强弱或者特定频率的声音，也就是不能识别一句语言，所以把YL-56作为声控启停开关是非常合适的。总体来说该设计就是具有声控加避障功能的声控启停避障智能机器人。

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 .
