The most common commercial pitching machines are the “two rollers” type and also the “arm” type. These machines tend to have certain limitations. In particular it is very difficult to simultaneously change both ball speed and direction. Also some types of pitches, such as the curve or sinking ball, are not easily achieved. In this study, the hardware and software design of a new “intelligent” pitching machine which is able to pitch repeatably with selectable speed, direction and ball rotation, is presented. The machine had three rollers and the motion of each was independantly controlled by a heirarchical neural network. This network accepted ball speed, direction and rotation as inputs and produced detailed motion control of the three rollers as output.
