Abstract—The deep sea of the 4,000m grade is a treasure house of resources. However, there are no precise maps about the sea bottom shape. So, the authors have developed deep-sea drone with functions to make sensing marine bottom and make maps of the 4,000m depth grades. The drone shape durable in the deep sea is only a sphere. The authors have made a prototype of deep-sea drone by use of spherical ultrasonic motors. The authors have succeeded in driving it in underwater.
Index Terms—Ultrasonic motor, deep sea, drone, and spherical motor.
