A DC drive motor has a shaft connected to a horizontal arm for rotation in the forward direction, the shaft and arm will rotate in the opposite direction only when the ball is driven in the opposite direction by the user. Sensors are provided for detecting when the shaft is rotated in the opposite direction and by the user and for measuring the speed in the shaft when rotated in the opposite direction and a speech processor cooperates with the sensors for providing immediate audio feedback to the user.
