Abstract
This specification relates to robots and audio processing in robots. One aspect of the subject matter includes: a body and one or more physically moveable components; a plurality of microphones; one or more processors; and one or more storage devices storing instructions that are operable, when executed by the one or more processors, to cause the robot to perform operations. The operations can include: obtaining map data of an environment of the robot; selecting a test location from the map data; navigating to the selected test location; receiving a sound wave propagating through the environment of the robot; computing one or more acoustic transfer functions for the test signal, wherein each acoustic transfer function represents how the test signal was transformed by the environment of the robot during its propogation through the environment of the robot; and storing each of the transfer functions in association with the test location.
