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.

摘要-水上推进系统PIs？格鲁吉亚理工学院的Jarek Rossignac/南加州大学的伊娃坎索海洋中充满了各种各样形状和游泳方式的生物，但只有少数被研究过。水上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，以提高我们对游泳生物学和力学的认识。此外，其中一些未被探索的游泳方式可能会激发更好的人工游泳者的设计，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）发明用于水上运动的变形体的几何表示，以及用于组合它们的交互式工具，2）采用分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，我们将我们的合成运动与已发表的tunniform和carangiform鱼的尾驱动运动结果进行比较。 这种验证为我们对其他游泳方式的研究提供了信息，包括鳐翅膀状胸鳍的拍打，鲸鱼和海豚的垂直尾巴运动，沿着电鳗背鳍和乌贼外套沿着行进的波浪，海龟的划桨运动，龙虾的尾巴踢和水母的波纹铃铛。对于每种游泳方式，我们都设计了一个几何模型和一组参数化的行为，可以控制这些行为来实现协调运动和任务级目标。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有效性。
