Abstract
We focused on the physical customization of robots, and we developed a customizable communication robot "WEAR(Waseda Extendable ARchitecture)" which is installed the self-body-assertion (SBA) system which can accept / reject its user's customization. In this paper, we carried out an experiment which we let users navigate the robot to verify the effect of the easy understandable SBA. As the result, we confirmed the easy understandable SBA increased user's "friendship" and "activity".
