Collective actuation of microrobot swarms has emerged as a versatile tool to succeed challenging tasks for a single microrobot. However, the unpredictable interactions among the microrobots and segregated movements of the microrobots present inherent constraints for the multi-functionality system. Herein, we report an autonomous magnetic swarm of magnetic microrobots through programming magnetic anisotropy in the microrobots. Due to the magnetic anisotropy, multiple microrobots assemble in a deterministic manner. Hundreds of magnetic microrobots can agilely rotate in their frontal plane while preserving their assembled configuration. Through the pivoting, the magnetic swarm of microrobot assemblies with high chain length facilitates the capability to climb obstacle. Meanwhile, the magnetic swarm with high packing density can transport cargo via rotational force of the microrobot assemblies. We will discuss multi-functionality of the autonomous magnetic swarm capable to lift heavy obstacle, tumble high barrier, and cleave high surface tension materials.
