Abstract
The final goal of this study is to construct the safe structures for tele-ultrasound imaging diagnosis. As this diagnosis is used under the various medical situations, the personal safety measures of this diagnosis have to be strictly taken. To be concrete, this study has concentrated on the arms of that. A feasibility study has been performed in order to avoid the damage by a safety arm in motion of the robot. As the first step of the experiment, aluminum skin square tube with trigger has been adopted in order to arm have no bigger load than the human pain tolerance of 75N. This paper also conducts optimization of the trigger and support, fatigue test, downsizing of the arm and describes behavior of the safety arms by FEA.
