• H1: Participants will have a stronger Group Identification with a robotic partner that expresses GbE.
• H2: Participants will have a more positive perception of a robotic partner that expresses GbE.
• H3: Participants will have a higher degree of Group Trust with a robotic partner that expresses GbE.

Measures
Towards the robotic partner:
• Group Identification [1] (Satisfaction, Solidarity)
• Godspeed [2] (Anthropomorphism, Animacy, Likeability, Perceived Intelligence)
• Group trust [3]

Results
• Game scores were balanced
• Team GbE won 10 times, lost 11 and tied 3
• Team IbE won 11 times, lost 10 and tied 3
• The number of expressed emotions between robots was balanced
• However, there were more positive emotions than negative emotions

Results - Perception of the Robot
• Results showed no significant diferences in: • Perceived Intelligence (U = 200, p = 0.07), • Animacy (U = 275, p = 0.79), • Anthropomorphism (U = 276, p = 0.80).
• Participants attributed significantly higher levels of Likeability to robotic partner with GbE than the robotic partner with IbE.

Results - Perception of the Robot
• There was a strong, positive, and statistically significant correlation between Group Identification and:
• Anthropomorphism (rs = 0.529, p < 0.01)
• Animacy (rs = 0.318, p = 0.03)
• Likeability (rs = 0.606, p < 0.01)
• Perceived Intelligence (rs = 0.595, p < 0.01)

Conclusions
• We defined a model of GbE for social robotic partners
• User study with 2 fully autonomous robots using the model to generate GbE or IbE
• Our findings can improve interactions and create effective collaborations in HRI
• GbE revealed a promising role on the design of social robotic partners
