Abstract

An audio sensor system is presented that uses multiple cere-
bellar models to determine the acoustic environment in which a robot is operating, allowing the robot to select appropriate models to calibrate its audio-motor map for the detected environment. There are two key areas of novelty here. One is the application of cerebellar models in a new context, that is auditory sensory input. The second is the idea of applying a multiple models approach to motor control to a sensory prob-
lem rather than a motor problem. The use of the adaptive filter model of the cerebellum in a variety of robotics applications has demonstrated the utility of the so-called cerebellar chip. This paper combines the notion of cerebellar calibration of a distorted audio-motor map with the use of multiple parallel models to predict the context (acoustic environment) within which the robot is operating. The system was able to correctly
predict seven different acoustic contexts in almost 70% of cases tested.
