Abstract(in English) Magnetically compatible robots are required as haptic interfaces for neuroscience studies. The purpose of this paper is to develop an MR compatible robot using ultrasonic motors, which is able to work within an MRI/fMRI scanner and to acquire MRI images continuously during arm motions. In addition, the impedance control method of ultrasonic motors is discussed. The characteristic of voltage phase and motor torque is investigated experimentally, and these results are used for the impedance control of ultrasonic motors. The position dependent force fields and velocity dependent force fields are produced for the purpose of fMRI tests. And the effectiveness of these fields is tested with a force sensor. Also, MR compatibility is verified experimentally. Finally, some brain activities are investigated with fMRI during finger movements.
