Wireless drive and control of a swimming microrobot

摘要

A swimming microrobot actuated by two FMP (ferromagnetic polymer) fins was developed. The robot could be driven by external magnetic field wirelessly. Fabrication process and performance of the FMP actuators were presented. Working principle and scaling effect of the robot were analyzed. Experimental results demonstrated that the microrobot could swim under the water, and the speed and direction could be controlled.
