This project aims to the design, control and expressive capabilities of RoboQuin—a novel humanoid social robot. Although social robots have become more human-friendly, their capacity for naturalistic human behavior remains relatively limited. We implement an interdisciplinary design method to create a realistic and natural humanoid robot, with accurate body proportions and smooth motion coordination, and the ability to perform nonverbal communication. With this design, we aim to explore the impact of robot body design and dynamic robot postures on human perception towards robots.
