Claim 15:
16. A method for training a device to verify 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;
establishing a first controlled environment with low ambient noise;
performing a first sequence of training connections under the first controlled environment in which two or more components are connected to a desired connection status using the gripper, wherein connecting the two or more components produces a connection sound;
receiving first audio signals from the plurality of audio sensors to a controller input during the first sequence of training connections;
establishing a second controlled environment in which ambient noise corresponds to a usage environment;
performing a second sequence of training connections under the second controlled environment in which two or more components are connected to a desired connection status using the gripper;
receiving second audio signals from the plurality of audio sensors to a controller input during the second sequence of training connections; and
processing, by a neural network, the first and second audio signals received from the plurality of audio sensors during the first and second sequences of training connections, respectively, using independent component analysis, wherein the processing, by the neural network, of the first and second audio signals includes isolating the connection sound from the ambient noise based on differences in phase delay and signal composition between audio signals in the first and second audio signals to produce training audio data.
