Flying insects and hummingbirds demonstrate remarkable aerial maneuverability, robustness, and resilience to their environment and their morphological changes. Upon a looming threat, hummingbird can perform a rapid 180-degree escape turn in just six wingbeats; Hawk moth can adjust to real-time wing area loss during hovering; Migrating butterflies can tolerate wind gusts disturbances while flying thousands of miles. The interest in micro air vehicles capable of hovering and fast maneuvers has led to several efforts to develop bio-inspired insect and hummingbird robots. However, it is only through the understanding of their underlying flight mechanisms can we create novel robots with key bio-inspired principles that allow them to approach the performance of their natural counterparts. To this end, we use a combined approach of dynamics and control theories, fluid experiments, and robotic platforms. In this talk I will highlight our recent findings including: 1) Learning extreme maneuvers such as rapid escape and tight body flips on an at-scale hummingbird robotequipped with just two actuators; 2) Sensing through flapping wings and their resilience to cluttered environment and dynamic morphological damage; 3) Flapping wing in turbulence and its gust mitigating potentials.
