Initial sample of emotional bodily expressions for the nao robot

Abstract: To investigate human-robot interaction with the NAO robot using emotional body language, we used this sample of photographed expressions to validate bodily expressions reflecting the 24 subemotions from Plutchik’s wheel of emotions. For each of the subemotions, we created two to three different expressions based on related works using Choregraphe version 2.8.10. Each expression was photographed twice: with neutral (white) eye LEDs and with colored eye LEDs matching the colors in the Wheel of emotions. In total, 112 pictures were shot using constant lighting, angle, and background. Participants assigned emotion labels to the freeze frames of the social robot NAO V6 included in this repository.
