Magnetic microrobots have been identified as a functional tool for robotic systems. However, the multiple tasks through local magnetic interactions between the microrobots has rarely been achieved. Herein, we introduce magnetic swarm by programming the magnetic assemblies between microrobots. By programming magnetization of microrobots, the configurations of robot assemblies could be diversified to head-to-tail and slippery-co-facial assembly. A magnetic swarm comprised of microrobots exhibited multi-functionality dependent on the configurations of robot assemblies. The magnetic swarms also exhibited pivoting or rotating motion according to the directions of the external magnetic fields. Through the pivoting, the robot swarm with high assembly length facilitated the capability to climb obstacles. Whereas, the robot swarm, constructed of slippery-co-facial assemblies, the robot swarm can transport cargo via rotational force of the magnetic assemblies.
