Developing a new carrier system with throwing and catching robot

Control of an object-throwing and catching robot is examined in this paper. We develop a new carrier system which uses two robots, thrower robot and catcher robot. In order to realize this system, we need to know problems which could happen in throwing and catching motion of these robots. Therefore, we have to produce a preliminary experiment system by a linear slider which has two sliders, thrower slider and catcher slider. In this experiment, the thrower slider throws a ball by inertial force, and the catcher slider moves automatically to point of fall of the ball with information about velocity of the thrower side. The experiment has following results. First, points of the thrown ball differ a little from each result in spite of the same condition. Second, we can find it is important to improve the accuracy of throwing a ball to a target position. In this paper, we show the structure of the preliminary system, and the verified problems about this system.
