The first phase of the IEEE Signal Processing Cup 2019 included a bonus task: participants could send their own recordings of drone egonoise to obtain extra points. In robotics, egonoise refers to the noise self-produced by a robot at its acoustic sensors, e.g., by its actuators.
This task was a success, as 10 teams sent very valuable egonoise data. This allowed us to gather a unique database of drone-embedded recordings, which is made publically available here for research and education purpose, as agreed by participating teams.
