Magnetic soft robots have enabled untethered locomotion at ambient environment to travel in diverse intermedia with high penetrability compared with light or solvent-driven systems. However, the simultaneous magnetic manipulation of multi-soft robot is challenging since the individual regulation requires programming complex directional magnetic fields or generation of localized magnetic fields. We demonstrate that the orbital regulation of multi-soft robot actuated by a single rotational magnetic source at the center, inspired by revolving planets in the solar system. The hierarchical maneuverability-rotation and orbital revolution- resulted in 60 BL/s velocity which is 250 times faster and 198 times lighter weight (177 µg) than the reported soft robots at below 0.028 T magnetic flux density. We will discuss the multimodal behavior of rotating, pivoting, tumbling in the rotation modes, leading to facile on-demand regulation of orbital radius, velocity and pathway of collective system. |
