As microscopic swimmers survive in nature, they have evolved unique structures and swimming patterns under the water, which has special advantages. The movement of bacteria at low Reynolds number (Re) environment has aroused extensive research interest. The two typical swimming methods of bacteria are introduced in this paper. Based on this, we are inspired to design the bionic robot on a micro-scale, which is an artificial structure that imitates the external shape, movement principle and behavior mode of organisms in nature. Compared with traditional robots, nano bionic robots are easier to miniaturize[1]. They also have higher maneuverability so that they can move continuously and flexibly. We expect to simulate its motion at low Reynolds number (Re) fluids and explore complex future applications in different fields.
