Echord Monitoring Public Summary on October, November 2011

InterAID experiment has achieved all the objectives of the planned activities. Nevertheless the experiment has been extended accordingly with the EU Commission (Amendment III) in order to better test the solution and to implement/improve some features requested from the users during the field tests.

In this two-month period, the following activities have been performed:

• Data base integration: after each inspection the robot sends the data acquired to a server pc where they are stored in a data base. A graphical user interface permits to search, extract and visualize the data.
• Improvement of the platform control algorithms: the washing machine detection algorithm, that permits to the robot to properly move in front of the washing machine, has been modified adding additional processing steps for filtering the laser data and supplementary controls to avoid “false detections” or wrong identifications.

Task 3: Implementation of diagnostic functions

Activities performed:

• Diagnostics strategy definition and implementation: the status of washing machine under test is autonomously detected from the image acquired using a high resolution 2D camera; depending on the WM status (off, idle, washing, error) a different sequence of interaction operations (button pushing, knob turning, door opening) and measuring tasks (vibration, noise, image acquisition/analysis) are performed.
• User interface implementation: a Graphical User Interface (GUI) running on a touch screen mounted on the robot permits to visualize what are the operations already performed by the robot and what the robot is going to do, as well as to directly interact with the robot itself.
• Laboratory tests: the developed prototype has been successfully tested in an environment reproducing a real life-test laboratory where several washing machines of different models are present.

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.).
