<p>A baseball pitching machine is diclosed preferably employing a counter-rotating wheel-type baseball launch subsystem (10) for selecting the type and percentage of pitches, pitcher, batter characteristics, strike zone areas, and other parameters to provide a meaningful batting training session. The pitching machine (10) includes a ball transport subsystem including a carousel (25) for receiving and transporting baseballs in sequence to a position adjacent the counter-rotating wheels (20, 21). While being transported, each baseball (B) stops at seam orienting stations where seam rotators (26A, 26B) rotate the baseball to provide a commanded seam orientation for the particular pitch selected. The baseball is oriented by the ball orient (27) for insertion in the launch subsystem (17). A computer allows the selection by the operator of a variety of pitches, random or selected order. The computer has memory capability for storing pitches corresponding to any pitcher's typical pitch pattern and the system includes video, audio and data recording to record each batting session.</p> |
