Abstract
Recently, problems of low master of the techniques by students of Department of Dentistry and trainees due to decreasing numbers of patients and increasing numbers of dentists are raised. To address the problems a dental patient robot that operates in a similar manner to an actual patient was developed. At present, because the neck mechanism uses a gimbal mechanism, the range of motion for the vertical and horizontal directions is not sufficient. Therefore, it is necessary to carry out the development of new mechanisms and flexible multi-degree-of-freedom. Make new mechanism using a 3D printer. One hole in the center and three holes surrounding it were drilled. And it will drive in the rolling contact through the spring and wire. Also, the basic controlled to the basic one unit in this mechanism is calculated. I was possible to demonstrate the utility of the base unit.
