The ultimate goal of our study is to elucidate dominant factors and feedback information which facilitate embodiment of an extra robotic limb including a robotic thumb. In this research, our trials are to shift body representation and to evaluate how body schema is modified after use of the robotic thumb. As a result, proprioceptive drifts and task performance improved when subjects controlled the robotic thumb without visual confirmation of its posture. And after performing a grasping task execution with the the robotic thumb the modification of body schema is conformed.
