Abstract: Micro-mouse is a microprocessor controlled micro robot that integrates the multiple functions of environment perception,dynamic decision-making and planning,behavior control and implementation.The traditional design of micro-mouse uses a stepping motor which is easy to control but has low rotate speed.The paper introduces the design of DC-drive micro-mouse with low cost and high reliability which fully considers the requirements of competition.Simulation tests shows that this system can complete the task of maze contest successfully.

Key words: micromouse, drive, DC motor
