英文摘要： A novel modular self-reconfigurable mobile relay microrobot is proposed, which adopts the reconfigurable way of power and wireless communication relays, so as to enlarge its individual detection range by collaboration among multiple units. The movement mechanism of the microrobot actuated by electromagnetic micromotors and its electromagnetic microconnector (unilateral size<4mm) with mechanical and electrical interfaces are respectively designed based on MEMS technology. The dynamic model of the microconnector is established, and then the optimal design method of its parameter is researched by FEM (Finite Element Method). The modular design method of the microrobot and the miniaturization technology of its control system integration are respectively studied. The fabrication method based on UV-LIGA and ultra-precision machining technologies of the microrobot is set up. The IR positioning system of the microrobot is designed with the goal of least hardware consumption, and then the positioning methods based IR RSSI (Received Signal Strength Indication) in long range and IR CA (Centering Alignment) in short range are researched. On the basis, the proximity control method and strategy between the microrobots are researched, so that it has the capacity of autonomous docking in long range (0-3m) under the condition of
