Development of mobile robotic cart to support HOT patients

-Specification design of the cart to be lightweight and get over the obstacles-

Abstract

Home Oxygen Therapy (HOT) patients must take the conveyance cart to carry oxygen equipment when they go out. However the equipment is heavy enough to discourage the patients from going out. Therefore we attempt to develop a mobile robotic conveyance, which is similar to the wheeled walker, to support HOT patient's going out.In this paper, we describe the mechanism of our developed prototype robotic cart which is lightweight and has a capability of getting over the steps or obstacles on the road.
