| Outline of Final Research Achievements |
We developed the micro ultrasonic motor with a one cubic millimeter stator that can generate over 10μNm and studied its application technologies for a medical microrobot. We attempted to improve the motor characteristics such as the motor output and stability, and coupled a new micro gear unit to the micro ultrasonic motor. The resulting torque shows 100mNm, which is 100 times larger than that without a gear. The micro ultrasonic motor-driven pan-tilt mechanism and linkage mechanisms are studied: the dynamics of the mechanisms are modeled and verified by experiments. There are two other achievements in this study: (1) We built a micro linear ultrasonic motor with 2mm stator, which is one of the smallest linear motor. (2) We derived the scaling law that shows how the micro ultrasonic motor behaves at smaller scale.
