Magnetic manipulation of soft robotic systems has advantages of producing fast locomotive responses at ambient conditions that can also operate in diverse media with high penetrability. However, parallel regulation of each individual magnetic soft robot remains a major challenge in multiple robotic systems. In this presentation, parallel magnetic regulation of multiple twisted microbots, composed of polyurethane-iron oxide nanocomposites, will be demonstrated by simply varying the speed of planar magnetic rotation underneath the substrates. The magnetic robots involve on-demand switchable trimodal rotation (rotating, pivoting, and tumbling) and resultant orbital revolution. The hierarchical magnetomotility enables self-correcting locomotion in barrier environments as well as multi-terrain navigation including stairs and uphill climbing. Finally, ant-inspired collective behaviors will also be discussed for magnetic soft robots in multiple systems. |
