Claim 0:
1. A device for verifying a connection of components connected by a gripper, the device comprising:
a plurality of audio sensors configured to generate audio signals in response to detecting sounds, the sounds including background noise and a connection sound produced by two or more components being connected together;
a fastener configured to secure the plurality of audio sensors at different positions on the gripper; and
a controller comprising:
a controller input configured to receive the audio signals from the plurality of audio sensors;
a neural network configured to isolate the connection sound from the background noise in the audio signals received from the plurality of audio sensors 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 the independent component analysis by the neural network comprises an analysis of 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
an output interface configured to indicate that a desired connection status has been achieved based on the isolated connection sound.
