Meal-Assistance Robot Using Ultrasonic Motor with Eye Interface

Abstract

This paper proposes a meal-assistance robot that uses ultrasonic motors (USMs) and an eye-interface. The proposed robot is designed with simple manipulators moving in orthogonal coordinate axes to avoid unsafe motion and vibration. With the application of USMs, the proposed robot has excellent features. In particular, because it does not interfere with other electronic devices, the proposed robot is satisfactory choice for medical and welfare facilities. Moreover, the proposed robot is designed to be controlled with an eyeinterface, which makes this robot much easier to use than previous models. The structure of the robot is introduced and its effectiveness is confirmed by experiments.
