Design of Microrobot Driving System Based on Magneto Optical Cooperation

Micro robots are small in size and have the potential to work in space that is difficult to reach under conventional conditions. They have broad application prospects in biological engineering, physical chemistry and other interdisciplinary research fields. However, due to its small size, it cannot carry its own energy, so it needs to be driven by external physical field. In the face of more complex task scenarios, a variety of micro robots may be required to solve the problem together, so they may have different characteristics. When controlling such a robot cluster, if only a single physical field is used, the accuracy may be low or even impossible. Aiming at this pain point, we propose a driving method using hybrid dual physical fields, which improves the accuracy and efficiency of control on the basis of ensuring biological compatibility. By integrating the electromagnetic drive system and the optical tweezers drive system, this method can realize the separate control of a single target and the separate and unified control requirements of the cluster target.
