Robotics combines the precision machinery , microelectronics and computer , automatic control and drive technology , sensing and information processing, artificial intelligence and bionics and other disciplines the latest research results , is a multidisciplinary integrated technology . The emergence and development of robot technology , not only the traditional industrial production and scientific research fundamental change , but human social life will have a profound impact . Currently, studies in robotics , mobile robots due to its practicality and intelligence , are more and more people 's attention. This paper describes an approach based on TMS320F2812 is designed wheeled mobile robots. The design of the robot , first detailed analysis and design of the system architecture of the mobile robot , the system structure comprises mechanical structure and electrical structure of two parts. The mechanical structure of the mobile robot using a common wheeled mobile trolley structure, using two-wheel differential drive movement. While its electrical structure comprises a processor module, the information collection module , actuator and drive control modules and other functional modules. Then according to its electrical system architecture framework to design and implement their control system hardware circuits, including DSP minimum system, power module circuit , keyboard, display circuit , information gathering circuits, communication circuits , driver board circuit. Finally, on the basis of complete hardware circuit design and preparation of control system software program that enables the display of the sensor data , without reference tracing the non- navigation exercise, when the ground has white lines tracing navigation exercise, as well as the task of grabbing and moving goods . Further, in the robot system designs, in order to have a sustainable development capacity reserved for a sufficient number of I / O interface and the communication interface , so that it requires only a simple increase in sensors and other devices of the robot can be realized function expansion .
