摘要： An automatic ball launcher includes a ball feed control system that includes a meter wheel with radially-spaced ribs or grooves to selectively block and pass balls to the flywheels of the launcher. The meter wheel rotates to selectively block and release a single ball to pass at a time. The controller of the launcher can be programmed to stop the meter wheel when a ball has been metered by monitoring the current at peak of the motor driving the meter wheel. A meter-event can be determined to have occurred when the current of the drive motor drops to a trough by a pre-set magnitude following a rise to a peak value. A remote control can be provided for the user to operate the launching machine and adjust a plurality of parameters.
