This paper describes the automatic calibration of a set of air ow sensitive sensors on a robot exposed to unknown random air ow stimuli. This might support the idea that the cricket cercus neural system in the terminal abdominal ganglion is evolved by learning. The algorithm makes use of the singular value decomposition (SVD) and the known reduced model dimension of the system for learning the sensor array setup. The absolute orientation of the array can only be found in function of a reference ow or reference sensor which must be calibrated manually. When only a change in airow measure is needed, the reference sensor can be left uncalibrated.
