MRI-Compatibility of a Manipulator using a Spherical Ultrasonic Motor
We report the development of a manipulator using a spherical ultrasonic motor (SUSM) and the magnetic resonance imaging (MRI)-compatibility of the SUSM. The SUSM is constructed of three ring-shaped stators and a spherical rotor and has two or three degrees of freedom (DOF). In the present study, a novel SUSM composed of non-magnetic materials has been constructed. In an MRI-compatibility test o...
متن کاملDevelopment of spherical ultrasonic motor for pipe inspection robot
We present a pipe inspection robot using a newly developed spherical ultrasonic motor (SUSM) as a camera actuator. The novel SUSM has improved the range of movement compared to previous SUSMs, and the robot can point a camera in any direction. In this study, we determined a method for controlling the rotational direction and strategic control from the kinematics and characteristics of ultrasoni...

متن کاملPositioning Control System of a 3-Dimensional Ultrasonic Motor with Spherical Rotor
This project is concerned with the design of the control system for the accurate positioning of the spherical rotor of an ultrasonic motor equipped with piezoelectric actuators. The motor is intended to be used for trajectory following of flying objects as well as to support human articulations (shoulder, knee) of handicapped. The ultrasonic motor has 3 stators with piezoelectric actuators in a...
متن کاملa study on rate making and required reserves determination in reinsurance market: a simulation
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
