The subject of this thesis is to find a way to manipulate the bodily dominant / submissive expressions of robotic behaviors. The expression of emotion is an important part of the development of Socially Interactive Robots. Previously, studies about the robotic emotions usually focus on single behaviors. Because the generation and testing of new behaviors are time consuming, this kind of emotional manipulation procedure requires a lot of work when applied in practical use. The innovation of this thesis is to explore a solution that can modify the dominance level of a wide range of robotic behaviors without the re-creation of new behaviors. The results of this work can be used for the design of the robotic movements and the development of robotic applications.
