TRABot coordinates speech, a digital face, and body gestures in a G1 humanoid. It selects reviewed robot motions using the reply’s ordered communicative meanings and duration, while streaming speech audio drives both speech playback and facial animation. In a user study, participants preferred the full system to matched random motion in 84.58% of decisions; gestures remain limited by its catalog.
