Dimensional analysis of spring-wing systems reveals performance metrics for resonant flapping-wing flight
Published in Royal Society Interface, 2021
Used a robotic model of a flapping insect with elastic energy storage to uncover the effects of inertial, elastic, aerodynamic, and other damping forces on the efficiency of flapping insects - and robots
Rapid frequency modulation in a resonant system: aerial perturbation recovery in hawkmoths
Published in Proceedings of the Royal Society B, 2021
Experiments show that hawkmoths blasted with a gust of air control their recovery in part by changing the frequency at which they flap their wings
Autonomous Actuation of Flapping Wing Robots Inspired by Asynchronous Insect Muscle
Published in IEEE International Conference on Robotics and Automation (ICRA), 2022
Made robots that flapped autonomously - with no control input - by designing a feedback law based on the dynamics of stretch-activated insect flight muscle
The hawkmoth wingbeat is not at resonance
Published in Biology Letters, 2022
A biomechanics model based on measurements of biological material properties and careful consideration of insect anatomy says that the hawkmoth Manduca sexta flaps its wing much faster than it would if it were trying to be as energy efficient as possible
Compliant thorax design for robustness and elastic energy exchange in flapping-wing robots
Published in IEEE International Conference Intelligent Robots and Systems (IROS), 2022
Developed a novel carbon-fiber and silicone flapping robot transmission for more robust centimeter-scale flying robots
