Abstract：The paper describes a mobile microrobot incorporating a novel type of electromagnetic micromotor. The overall dimensions of the microrobot are 12mm×8mm×6mm. Two micromotors are used to actuate the two driving wheels. As the key part of microrobot, the micromotor adopts the novel structure which could get larger output torque. Another merit of the microrobot is that it could be controlled in different ways to adapt the different applications. The controller controls the microrobot by flexible ultraminiature wires to move forward and backward, and turn left and right. The design, fabrication, structure, and performance of the microrobot are described in detail in the paper.
