Task 3: Implementation of diagnostic functions

Activities performed:

• Application sensor data analysis: data collected from washing machines using the microphone mounted on InterAID Robotic Arm allows identifying “noisy” washing machines.
• Diagnostics strategy definition and implementation: the positioning of the microphone respect to washing machine under test has been chosen in order to maximize the Signal to Noise Ratio (SNR) and number of information contained in the spectra of the signals acquired.
• User interface implementation: a Graphical User Interface (GUI) permits to define the list of operations to be performed on the washing machine under test depending on its model and its state (off, waiting, washing, error, etc.).
