This dissertation discusses fundamental issues in the development of a micromouse, utilizing the knowledge in electronic circuits, sensors and the microcontroller. The objective of this project is to develop a maneuverable micromouse that hasthe capability to navigate in the maze and find its way out of maze. A detail design of the micromouse systems is presented. A maze solver for demonstrating the maneuverability of the micromouse has also been developed. A micromouse is a miniature electro-mechanical robot, typically consisting of three main subsystems: the drive system, an array of sensors and the control system. To illustrate the integration of the three systems in the micromouse, a general block diagram has been constructed. The first block is the sensory systems which generate the input to the microcontroller systems. The selected sensor is the IR detector that uses the reflective motion in order to detect the mouse position. This kind of sensor is sensitive enough for the project and commonly used for IEEE Micro Mouse Competition .The second block is the microcontroller systems that obtain the input signal from input pins and determine the appropriate algorithm for the output systems. The chosen microcontroller is Intel 8031 and had to be programmed by using the ASM51.The third block is the stepper motor. The reason for choosing the stepper motor is that we can easily adjust the direction and the speed by programming. The final product is the combination all the three block systems. This report describes on the fundamental concepts required for micromouse design which are the infrared sensor systems, Intel 8051 microcontroller system and stepper motor drive systems. Focus of the project is primarily on the infrared sensor system and maze solving algorithm which are the critical part ofthis project.
