摘要--水上推进实验室？Jarek Rossignac，佐治亚理工学院/伊娃·坎索，南加州大学海洋中充满了各种形状和游泳方式的生物，但只有一小部分人被研究过。水生推进实验室的目标是创建计算机工具，用于逆向工程和评估跨物种的水上运动策略，以提高我们对游泳的生物学和力学的知识。此外，其中一些未被探索的游泳方式可能会启发人们设计出更好的人工游泳器，用于水上探索、工程和医学。创建的工具、数据集、动画和游泳风格的数字模型将提供给其他研究人员、学生和教育工作者。我们的研究结合了：1)发明了用于水上运动的变形体的几何表示法，以及将它们结合起来的交互工具；2)使用解析和数值技术来模拟这些数字游泳者的运动；以及3)开发控制和优化方法，使我们能够为给定的身体找到最有效的运动策略。为了验证，我们正在将我们的合成运动与已发表的锥形和脉管形鱼的尾巴驱动运动的结果进行比较。这一验证为我们对其他游泳方式的研究提供了信息，包括鱼翅状胸鳍的拍打，鲸鱼和海豚的垂直尾巴运动，电鳗和乌贼外套膜上的行波，海龟的划桨运动，龙虾的尾巴踢和水母的涟漪铃声。对于每种游泳方式，我们正在设计一个几何模型和一套可以控制的参数化行为，以实现协调运动和任务级的目标。我们也在研究这些游泳方式在不同的流体条件和目标下的效果。

Abstract - Aquatic Propulsion LaboratoryPIs ? Jarek Rossignac, Georgia Institute of Technology / Eva Kanso, University of Southern CaliforniaThe oceans are filled with creatures with a wondrous array of shapes and swimming styles, yet only a small number of these have been studied. The goal of the Aquatic Propulsion Laboratory is to create computer tools for reverse engineering and evaluating the aquatic locomotion strategies across species in order to advance our knowledge of the biology and mechanics of swimming. Moreover, some of these unexplored swimming styles may inspire the design of better artificial swimmers for use in aquatic exploration, engineering, and medicine. The created tools, data sets, animations, and digital models of swimming styles will be made available to other researchers, students, and educators.Our research combines: 1) inventing geometric representations of deforming bodies for aquatic locomotion, and interactive tools for combining them, 2) employing analytic and numerical techniques for simulating the motion of these digital swimmers, and 3) developing control and optimization methods that allow us to find the most efficient motion strategies for a given body. For validation, we are comparing our synthetic motion to published results of tail-driven motion of thunniform and carangiform fish. This validation informs our study of other swimming styles, including the flapping of the wing-like pectoral fins of rays, the vertical tail motions of whales and dolphins, the traveling waves along the dorsal fins of electric eels and the mantles of cuttlefish, the paddle-driven motion of sea turtles, the tail kicks of lobsters and the rippling bells of jellyfish. For each swimming style, we are designing a geometric model and a set of parameterized behaviors that can be controlled to achieve coordinated motion and task-level goals. We are also conducting studies of the effectiveness of these swimming styles under different fluid conditions and goals.
