Title    Program Design of Maze Micro Mouse                 

Abstract

The micro mouse is a typical micro robot, which includes embedded microcontroller, sensors and mechanical motion. The micro mouse can choose a best and fast way to the destination in the maze, with automatic memory. Based on the microcontroller system, the subject focuses on designing related software for maze computer mouse. The designed software include the identification of key-press, the infrared distance testing program, stepping motor controlling program, the forward-straight program with revision of posture position, turning program and maze procedure program and so on. The subject focuses on the study of the working principle of photo-electric reflective sensor and stepping motor, and the design of distance testing module and motor controlling module used in the walking procedure of the micro mouse. Students can improve their programming capability.

This paper firstly introduces the origin and development of micro mouse. Then it analyses the micro mouse's hardware composition and working principles. After that we discuss the design and implementation of the software. .It includes the identification of key-press, the infrared distance testing program, stepping motor controlling program, the forward-straight program with revision of posture position, turning program and maze procedure program and so on. At last, the problems appeared during my studying process are discussed and summarized.
