Robotics research is a hot direction at home and abroad in recent years. In high-risk industries, in order to enhance the control of robots, in many cases，the controller needs to know the real-time information on the spot to take the proper strategy quickly.
And as personal digital assistants，also known as the Pocket PC, PDA has integrated some routine function, such as calculation, communication, and information query and so on .But the most important one is the function of the long distance communication which provides the possibility of considering PDA as a mobile robot remote controller.
As the core to the embedded system, the embedded technology with its wide application, widely are used in industrial control, transportation management, information appliances, intelligent home management systems, network and e-commerce, environmental monitoring and control of robots, and other fields. The development of robot technology and embedded systems are closely linked with the development of robot technology of the embedded technology applications, and embedded technology will promote the development of intelligent robots.
This design chooses Samsung S3C2410 as the microprocessor which has an ARM ARM920T core, and based the MPU, some hardware will be extended and the software system will be chosen to design and realize a simple PDA system. At the course of the system design and implementation, first, the function modules including LCD display touch screen were designed; the hardware drivers were developed based on the system. And the interruption program will be introduced .At last ,there will be the link of the relative hardware.
