Abstract
Home Oxygen Therapy (HOT) patients need portable oxygen equipment at the time of going out. However, the currently-used oxygen equipment is enough heavy to discourage HOT patients from their going out. Therefore we try to develop the power assist robotic cart which supports HOT patients' going out. Especially we try to develop the side-moving type cart which moves next to the users. We propose new operation interface device which has high reliability and capability of easy-understandable operation, and then we verify its validity by dynamical simulation applying Open Dynamics Engine. In this paper, we report the result and show the effectiveness of our proposed interface device.
