Small‐scale actuators capable of performing multiple tasks are crucial for the advancement microfluidic technologies. These enable high‐throughput operations and support integrated solutions across a wide range applications. In this study, multipurpose magnetic microactuator (MMA) is developed with two pairs arms controlled externally through custom‐built electromagnetic system. To enhance navigational precision, circular sections named “mobility components” into MMA's design.

Microrobots with different structures can exhibit multiple propulsion mechanisms under external magnetic fields. Swarms dynamically assembled by microrobots inherit the advantages of single microrobots, such as degradability and small dimensions, while also offering benefits like scalability high flexibility. With control fields, these swarms demonstrate diverse perform precise actions in complex environments. Therefore, relationship between their is a significant area study. This paper reviews examining structural design, methods, mechanisms, practical applications. At first, we introduce design including materials manufacturing methods. Then, describe field generation systems, gradient, rotating, oscillating characteristics. Next, analyze individual way assemble into swarm an field, which illustrates swarms. Finally, discuss application water purification targeted delivery, summarize current challenges future work, explore directions.
