Characteristic Evaluation of a Novel Type of Microrobot

A microrobot that can move along blood vessels has a great potential application for microsurgery. And also, the development of a wireless microrobot that can be manipulated inside a tube by adjusting an external magnetic field has been discussed. The model of the microrobot utilizes an electromagnetic actuator as the servo actuator to realize movement in biomedical applications. The structure, motion mechanism, and characteristic evaluation of a driving fin for the microrobot have been discussed, and the movement of driving fin can be controlled via frequency of the input current. The moving experiments have been carried out in horizontal and vertical direction by changing frequency. The microrobot has a rapid response, and it can clear out dirt which is adhering to the inner wall of pipe. This microrobot will play an important role in both industrial and medical applications such as microsurgery.
