Robot arm is desired not to vibrate on operation. Then, we examine the relationship between vibration suppression and shape of robot arm. We prepare some beams which have different shapes but equal weight, which are regarded as robot arm. And we measure the strain of the rotating arm for the examination. The robot arm rotates horizontally and the gravitation can be ignored. From experiment results, we show the tapered arm is more effective to suppress the vibration of robot arm.
