Abstract
Methods, systems, and apparatus for drone collision avoidance and acoustic sensing are disclosed. An example apparatus to detect acoustic data from a drone includes a controller to set a target revolutions per minute (RPM) for a motor of the drone. The controller is to modify the target RPM based on a modulation pattern to cause the motor to rotate a propeller of the drone at a modulated RPM. The modulated RPM creates self-generated noise. The example apparatus also includes a sensor to gather acoustic data and an analyzer to remove the self-generated noise from the acoustic data to create external acoustic data for processing.
