Abstract
Home Oxygen Therapy (HOT) patients who are suffering from Chronic Obstructive Pulmonary Disease always need to be supplied high concentration oxygen, and they also need to carry portable oxygen cylinders. However the oxygen cylinders seem to be heavy for carrying. So we propose and develop new type of robotic cart for carrying oxygen cylinder to support HOT patients. Our proposed robotic cart applies compliance control to operate the cart itself easily by using handle shape interface which is usually attached to the popular carry cart, and then the robotic cart becomes to be able to follow the patients by carrying their portable oxygen cylinders. In this paper we describe the principle of robotic cart operation, hardware development, controller design, and their effectiveness.
