What if a drone could follow another drone simply by listening to the sound of flight? After more than 2 years of work, I'm excited to share SonicFly, our new work on embodied passive aeroacoustic perception. SonicFly enables one UAV to estimate and follow another using only the leader’s naturally generated flight sound, without GPS sharing, inter-robot communication, active acoustic signaling, or external sensing infrastructure. What sounded simple turned out to be a very challenging robotics problem. We went from designing the microphone array and understanding rotor acoustics to learning relative state and closing the loop for real outdoor aerial pursuit. Paper, video, code: Kudos to our amazing students Yanbaihui (Evelyn) Liu, Ravi Prakash, Li-Yu (Patrick) Lo, and Nils Roede! 🚁🎧 I am also very grateful to our other lab members, in particular Tate Staples, Jiaxun Liu, and partner Ben Borger, who helped make this possible.
