Contactless manipulation of soft robots by external magnetic field provides the regulation capability even in physically blocked environments. However, parallel multi-body control remains a major challenge of magnetic soft robots because differently programming locomotion of each untethered soft robot is difficult. Herein, we demonstrate on-demand parallel regulation of multiple polymeric robots via hierarchical magnetomotility of orbital rotation and revolution. Orbital radius, velocity, and pathway of the magnetic soft robots are regulated by varying rotational frequency of magnets underneath the substrates. In this presentation, we will discuss the mechanism of the trimodal rotation of rotating, pivoting, and tumbling which enable multi-body controls of different aspect ratio of soft robots. We will also discuss navigation of the polymeric robots in diverse terrains including stairs, uphills, and barriers via orbital maneuver. |
