Nowadays, it is still tough to get a robot to appear in a humanistic natural way as robots tend to be static, whether they move or not. As a more natural human-robot interaction is wanted, the behavior of social robots needs to be improved on different levels. In this project, the main focus will be on the movements that make a robot appear more natural and lifelike, which are the idle movements. The objective of the research will be to find out which idle movements make a robot appear in a more natural way. For this research, the NAO robot by SoftBank Robotics is used.
