PDA，英文全称Personal Digital Assistant，即个人数字助理，一般是指掌上电脑。随着信息技术的的飞速发展，PDA集中了计算、通信、信息查询等常规功能外，还集成了电话、传真、娱乐和网络等功能。在这里，我主要是使用它的通信这一个功能。
移动机器人是一个涉及高端技术的行业，其发展历史不长，但发展很快，像美国NASA研制的火星探测机器人“索杰那”于1997年登上火星，而日本在这领域发展也很突出，不仅研制出了用于海洋探测等恶劣环境下工作的机器人，还开发出了用于娱乐的移动机器人。在我国，移动机器人起步较晚，大多数研究尚处于某个单项研究阶段。
本文主要是围绕PDA对移动机器人的控制来展开的。PDA采用ARM920T微处理器，支持USB的无线网卡通信方式，通过VC++在EVC编译器下完成通信协议的编程，实现信息准确无误的传递。对通信协议的编写，在这里使用套接字（socket）来完成，这种方式容易理解，也容易实现信息准确无误的传递。通信系统的发展过程也是移动机器人的发展过程，二者是相辅相成的，我们需要将移动机器人送到恶劣环境下去工作，但也需要移动机器人给我们带回现场信息，这就需要有一个好的通信系统，一套非常完整的通信协议，让信息能够很好的得到传递。

Abstract
PDA, the English full name is Personal Digital Assistant, which is personal digital assistants. generally, PDA refers to handheld computers. As information technology developing rapidly, PDA not only concentrates in calculation, communications, information Enquiries and other conventional features, but also integrates the telephone, fax, Internet and entertainment functions. Here, I use the function of communication primarily.
Mobile robot is a high-end technology industry. Its history is not long, but it develops very quickly. For example, the NASA of United States developed the exploration of Mars robot, "Sojourner",which boarded the Mars in 1997. And the Japanese developing in this area is also very Prominent, not only have developed the robot of working in a poor environment ,but also developed a mobile robot used for entertainment. In China, mobile robots are studied lately, the majority of work is still a single study in the research stage.
The article is about the PDA how to control the mobile robot . PDA uses ARM920T microprocessor, supports wireless LAN communications of USB card ,Prepares communication protocol in EVC compiler through VC, and then implements the accuracy of information transmission. For preparation of the communication protocol, where use the socket to complete. This means is easy to understand, and also is easy to achieve the accuracy of information transmission. The development of the communications system is also the development of the mobile robot, the two are complementary to each other, we need to send mobile robots to poor environmental conditions to work, but also we need to get back the information at the scene by the robot, which needs a Good communication system, a set of very integrity of the communication protocol, so that information can be transmitted very well.
Key words: PDA; Mobile robot; Wireless LAN; Socket
