Claim 12:
13. A method for verifying a connection of components connected by a gripper, the method comprising:
securing a plurality of audio sensors at different positions on the gripper using a fastener, the audio sensors configured to generate audio signals based on background noise and a connection sound produced by two or more components being connected together;
receiving the audio signals from the plurality of audio sensors to a controller input as the two or more components are connected using the gripper;
isolating the connection sound from the background noise in the audio signals received from the plurality of audio sensors by a neural network using independent component analysis that is independent of relative positions of the plurality of audio sensors to each other and to the two or more components and is based on training audio data obtained from audio signals received during a plurality of training connections made in a controlled environment, wherein using the independent component analysis by the neural network comprises analysing differences in phase delay and composition between the audio signals received from at least two of the plurality of audio sensors based on differences identified by the training audio data; and

outputting a signal indicating that a desired connection status has been achieved based on the isolated connection sound.
