自然界中的生物通过上亿年的演化，展现出了完美的身体结构和非凡的运动特性。生物趋于完美的特性，吸引了那些希望设计出更好的机器人的学者们的关注。受自然界中水生生物的启发，我们设计各种各样的仿生水下机器人。

　　Organisms have probably existed in the world for hundreds of millions of years. Their perfect physical structures and excellent locomotion properties emerging from the continuous long-period evolution fascinated all researchers who hope to design better mobile robots. Inspired by aquatic organisms, we design kinds of biomimetic underwater robots.
