Abstract:
Micro-robots wirelessly actuated by low-intensity electromagnetic fields can move in narrow environment and complete complex tasks, such as targeted drug delivery, micromanipulation, and environment detection. This paper introduces the advances of intelligent control of magnetically actuated micro-robots, mainly including the applications of intelligent control methods to the following areas: from rigid structure to flexible structure of magnetically actuated micro-robots, from single motion mode to multiple motion modes of magnetically actuated micro-robots, from open-loop control to closed-loop control of magnetically actuated micro-robots, from single individual and single swarm to multiple individuals of magnetically actuated micro-robots. Finally, the future development directions of magnetically actuated micro-robots are expected, including magnetic drives for larger workspace, micro-robots with more motion modes, medical micro-robots with flexible structures, autonomous navigation of micro-robots, and control of multiple magnetically actuated micro-robots.
