Wheelchair support by a humanoid through integrating environment recognition, whole-body control and human-interface behind the user

In this paper, we treat with wheelchair support by a life-sized humanoid robot. It is quite essential to integrate whole-body motion, recognition of environment and human-interface behind the user in order to achieve this task. Contributions of this paper is whole-body control including pushing motion using the offset of the ZMP and observation of the attitude outlier, recognition of the wheelchair using particle filter and human-interface behind the person using face detection and recognition of gesture.
