A novel insect-inspired flying robot, developed by TU Delft researchers from the Micro Air Vehicle Laboratory (MAVLab), is presented in Science. Experiments with this first autonomous, free-flying and agile flapping-wing robot -- carried out in collaboration with Wageningen University & Research - improved our understanding of how fruit flies control aggressive escape maneuvers. Apart from its further potential in insect flight research, the robot's exceptional flight qualities open up new drone applications.
