Abstract:

Flying insects can perform a wide array of extreme aerial maneuvers with exquisite accuracy and robustness, outmaneuvering any man-made flying device. A flapping insect is a nonlinear dynamical system subject to fast-growing mechanical instabilities that must be controlled to allow flight. Hence, similar to balancing a stick on one's fingertip, flapping flight is a delicate balancing act made possible only by ever-present, fast corrective actions. In this talk we will present a perturbation experiment with free-flying fruit flies that elucidates how flies control their rotational degrees of freedom: yaw, pitch and roll. Along roll, for example, flies respond to mechanical perturbations within a single wing-beat, or 5 milliseconds, making this correction reflex one of the fastest in the animal kingdom. These results, along with initial evidence for nonlinear control mechanisms, pose insect flight control as a potential model system for studying the neural mechanism of such fast stabilization reflexes.
