Development of operation interface of HOT patient’s outing support cart

- Improvement of controllability by force control I / F-

Abstract

Home oxygen therapy (HOT) is a medical treatment for patients who suffer from lung problems, and the patients must receive highly concentrated oxygen to maintain a constant level of oxygen in their blood. Thus, the patients must carry a portable oxygen. However, the total mass of the portable oxygen equipment is heavy enough to discourage patients from going out. In this paper we propose two types of operating I/F devices which detect the pushing force from the user to the robotic cart, then we show the effectiveness of them.
