Magnetic regulation of soft robots is attractive for contactless operation at ambient environment unlike other stimuli-responsive systems. To date, most reports on magnetic soft robots demonstrate single modal locomotion or multi-modal locomotion of single soft robot. Inspired by rotation and revolution of multi-planet in the Solar System, we investigate individual orbital maneuver of multi soft robots capable of multi-modal magnetomotility around a single rotational magnetic source at the center. In this presentation, the origin of hierarchical magnetomotility will be discussed along with the high performance of the soft robots including high velocity (60 BL/s) at low magnetic flux density (＜0.03 T) and light body weight (177 µg). We will further discuss facile on-demand switching of the rotational modes and regulation of orbital radius, velocity and pathway of multi soft robots. |
