Haru paper compares social robot embodiment against QTrobot

Evidence notes

• Researchers introduced Haru as an experimental expressive tabletop social robot and compared its embodiment with QTrobot and a baseline.
• The between-subject study involved 169 adults and evaluated participant perceptions of the different robot embodiments.
• QTrobot served as an established social-robot comparator in research on expressive design and human-robot interaction.
