Bats are the most dynamic and agile fliers in the animal kingdom, and, as such, they are excellent candidates for the inspiration of new flapping wing micro-air vehicle technology. The impressive flight mechanics of these animals is due to the complex nature of their wing structure. However, the simplicity of their muscle-tendon system suggests that the underlying mechanics of the wing motion is not as complex as it appears. The goal of this research is to determine how the bats control their wings to enable the development of flapping-wing micro-air vehicles which mimic the flight mechanics of the bat.The researcher will perform motion capture studies of bats in flight to determine wing and body motion during different flight maneuvers. This research will be conducted at Shandong University in Jinan, China under the supervision of an expert in the field, Dr. Rolf Mueller, who has studied bats for over 20 years. Over 100 species of bats have been documented in China which makes it an attractive location for observing cross specie trends in bat flight. To study these animals, a multi-camera motion capture array will be used to record high speed video of the bats in as many flight regimes as possible. Many viewing angles are required for this research because the highly articulated nature of the wing results in self-occlusion of important aspects of wing motion. The researchers are interested in capturing as many flight regimes as possible to determine how the bat controls different modes of flight. While similar research has been previously conducted, our experiments are novel for three reasons. First, limited motion capture data is available for Great Himalayan Round Nose Leaf bat, and to analyze cross-species trends in flight, more species data is needed. Second, we use many inexpensive cameras rather than few expensive cameras and have constructed a motion capture system for a fraction of the cost of commercially available systems. Finally, the researchers aim to create a repository of bat flight motion capture data that any researcher can use for extensions of this work including computational fluid dynamics simulations, motion estimation algorithm development, and micro-air vehicle design. This NSF EAPSI award is funded in collaboration with the Chinese Ministry of Science and Technology.

蝙蝠是动物王国中最具活力，最敏捷的传单，因此，它们是启发新拍打机翼微型航空技术灵感的出色候选人。 这些动物的令人印象深刻的飞行力学是由于其机翼结构的复杂性。 然而，它们的肌肉弯曲系统的简单性表明，机翼运动的潜在力学并不像看起来那么复杂。 这项研究的目的是确定蝙蝠如何控制翅膀，以使模仿蝙蝠的飞行力学的拍打翼微型空气车的发展。研究人员将对飞行中的蝙蝠进行运动捕获研究，以确定不同飞行手术中的机翼和身体运动。这项研究将在该领域的专家Rolf Mueller博士的监督下，在中国吉南的山东大学进行，他研究了蝙蝠已有20多年了。 中国已记录了超过100种蝙蝠，这使其成为观察蝙蝠飞行中的交叉规定趋势的吸引力。 为了研究这些动物，将使用多相机运动捕获阵列来记录蝙蝠的高速视频，以尽可能多的飞行方式记录。 这项研究需要许多视角，因为机翼的高度表达性质导致机翼运动重要方面的自我概括。 研究人员有兴趣捕获尽可能多的飞行方式，以确定蝙蝠如何控制不同的飞行模式。 尽管以前已经进行了类似的研究，但我们的实验是新颖的，原因有三个。 首先，有限的运动捕获数据可用于大喜马拉雅圆头叶蝙蝠，并且为了分析飞行中的跨物种趋势，需要更多的物种数据。 其次，我们使用许多廉价的摄像机，而不是很少的昂贵相机，并为市售系统成本的一小部分构建了运动捕获系统。最后，研究人员旨在创建一个蝙蝠飞行运动捕获数据的存储库，任何研究人员都可以将其用于该工作的扩展，包括计算流体动力学模拟，运动估计算法开发和微型空气车辆设计。 该NSF EAPSI奖与中国科学技术部合作。
