no-virtualCannot be tested on a simulated robot



When you run this behavior, the robot will track your face and tell you the expression it could detect on your face !

In this behavior the robot is only able to identify the facial expression of one person at a time.


  • Drag and drop the Movement > Motors > WakeUp box onto the Flow Diagram panel.
  • Connect its input to the diagram input.
  • Test -> The robot stands up.
  • Drag and drop the Sensing > Vision > Surroundings > Basic Awareness box onto the Flow Diagram panel.
  • Connect its input to the output of the WakeUp box.
  • Click on itsparameter-buttonparameter button.
  • Deselect all stimuli but the People Stimulus.

  • Test -> The robot tries to identify the facial expression of the person in front of him.
  • Drag and drop the Programming > Logic > Switch Case box onto the Flow Diagram panel.
  • Connect its input to the onStopped output of the Get Expression box.
  • Remove all existing cases from the Switch Case box and add the cases “happy”, “surprised”, “angry”, “sad” and “neutral”.
  • Test -> When the robot detected a facial expression, the Switch Case box triggers the corresponding output.
  • Drag and drop 5 Speech > Creation > Animated Say boxes onto the Flow Diagram panel.
  • Connect each of them with one of the grey outputs of the Switch Case box.
  • Double click on one of the Animated Say boxes and adjust the text in the Localized Text box as desired. Repeat this procedure for the other 4 Animated Say boxes.
