Abstract


With rising living standards, as well as scientific and technological level of the rapid development of information-based home life, the requirements of intelligent automation and increasingly high. Intelligent home service robot is the embodiment of high-tech, China’s "Eleventh Five-Year" period focused on the development of robot technology to the service robot. Yingbin robot on the study has important practical significance and practical application value. Service robot system is also set in mechanical engineering, electronics technology, computer technology, sensor technology, intelligent control technology and other technologies integrated system, the use of robots in the service sector, service requirements of the robot with high technological content and value to users with. No matter how complicated or sensor controller, the user is asked to operate as simple as possible, at the same time low cost. In this paper, robot technology Yingbin demand for low cost, low complexity, safe and reliable to carry out research and design robotics Yingbin.First of all, starting from the development of robots, service robots focuses on research and application of the status quo at home and abroad. Existing services in the analysis based on the robot, the use of new data-processing chips for guests to improve robot control system can be carried out with a certain degree of speech recognition, the realization of human-computer interaction to improve the control accuracy and response speed. In this paper, based on the ARM7TDMI core S3C44BOX-core processors as a control system, using its high performance, rich interface to facilitate the expansion of transplant and the advantages of a storage system to complete the circuit, power circuit, JTAG interface, as well as motor control, IIC interface hardware circuit design.Second, the guests also discussed the structure of the robot’s mechanical systems, robots from the control of Welcome to drive the implementation of research institutions and the design of the robot’s mechanical structure Yingbin. At the same time also on the robot-driven systems analysis and design, including the implementation of electric choice and choose a drive to match. The use of cost-effective to control a simple stepper motor driver through TT2D072A two-phase hybrid stepping motor driver, to adopt the external control mode, control of the stepper motor pulse and direction, which led to complete mechanical body walking movement.Finally, the design of the robot head movement Yingbin assembly structure, the structure of the production of the experimental device head and the head of the robot servo control movement experiment, and the results are analyzed. The experimental results show that the robot designed by the head of the mechanical system and the implementation agencies to better meet the guests control the robot’s movement.
