Meal assistance robot with ultrasonic motors

Abstract

In this paper, we develop a meal assistance robot for people with disabilities of upper limbs and pacemakers in the body. In the robot, ultrasonic motors are used because the motors do not generate an electromagnetic field. The robot is handled using acts of user's eyes so that the people can use it. Moreover, the vibration is small because the arms of our robot move independently of each other. In this paper, we introduce structure of our robot and show the advantage with experiment results.
