摘要机器人技术发展迅速，它涉及到的领域较多，如机械技术、电子技术、自动控制理论、计算机技术、人工智能、传感器技术等，这是集成许多种高科技技术发展的成果。本次设计面向避障机器人，是基于Arduino平台。在硬件设计方面，本文采用L298N直流电机作为电机驱动，在测距和避障方面，本文采用超声波传感器，通过超声波传感器来采集信号，将收集到的信号送入主控单元，让其处理数据，完成相应的工作。38502
本次避障机器人优点是基于Arduino平台，这是一种新的开发平台，有着很好的发展前景。当然设计的机器人也存在着不如意的地方，比如说探测的角度只能是正前方比较狭隘的角度，这是需要进一步改进和提高。

 Abstract Technological developments make life more convenient and better than before. Electronic technique gradually enters our life and our life is connected to it more tightly with great conveniences it has brought. It can be seen in many electronic products, such as phone, computer and camera, especially the smartphone, which has developed at a high speed in recent years. Electronic products upgrade just as fast as the high speed trend in this field. An evaluation board named” Arduino” has rushed out recently with its low cost simple and convenient development procedures and powerful functions. It can be connected to various kinds of transducers easily, which makes it a mobile and flexible .It consists of hardware(different types of evaluation boards) and software ( Arduino IDE ).
Many enterprises have promoted the embedded board which is simple and easy to operate, however, it is too hard for learners at the first stage. It is “Arduino” that has changed this difficult situation. People can complete the production of one electronic product quickly and develop or share information of this product through the application of “Arduino”. Nowadays, robot technology has also been improved a lot. In the past, many robots were made on the basis of singlechips. I applied the “Arduino” and designed a robot which can avoid obstacles. Although it is a application of simpleness. This topic is designed to make a don't need artificial control, can through the internal programming and combined with the various modules, make the obstacle avoidance of robot obstacle avoidance reaction.We choose to adopt two dc motor as the design of main drive, and then add in various sensors, through the sensors to collect all kinds of information, then we will deliver the collected information into the main control unit the Arduino microcontroller, let its processing data, complete the corresponding work.We choose to use H bridge driving circuit as dc motor drives, used to drive two dc motors;As for ranging and obstacle avoidance unit, we USES the ultrasonic technology, finally, the control unit the Arduino microcontroller, we will be the main modules together through accurate programming, these modules will be according to our ideas to complete the corresponding work, finally realizes the intelligent control.
