Effects of Magnetic and Viscous Torques on Underwater Swimming of Magnetic Soft Robots |
| 초록 |
Miniaturized swimming soft microrobots have been highly affected by viscous drag in liquid. Herein, we scrutinize effects of magnetic toque and viscous torque on orbital maneuver of magnetic soft microrobots in viscous solutions. Underwater rotation and revolution of the soft robot are induced by rotating linearly connected two permanent magnets. According to experiments and theoretical calculations for underwater swimming of the soft robots, uniform orbital maneuver of the soft robots is determined simultaneously by frequency of rotating magnets and liquid viscosity. Provided that magnetic torque is equivalent to viscous torque, hierarchical locomotion, evolving from rotation into revolution, is caused by pivoting and tumbling motion. Furthermore, we will discuss swimmability of the soft robots in liquid whose viscosity is comparable to that of human blood as well as the adaptive swimming which can cope with arteriosclerosis. |
