| CNC Control + Centrifugal Wrist |
| Centrifugal force created by the circular motion/velocity of the arm and the actual arm acceleration has significant affects on the position of the wrist at ball impact. Therefore, the operator has complete control of the wrist position at ball impact by simply varying the torque curves and release positions via the operator interface. One can input values to simulate a hands player whose wrist are ahead at impact, or a body player whose wrist are behind at impact, or the wrist and arm aligned at 6 o'clock at impact. The wrist position, in turn, controls actual ball trajectory. A hands player, for example, creates a high trajectory, whereas a body player creates a lower trajectory. In addition, like a human player, the centrifugal wrist responds differently with different club weights and lengths. |
| Rotating Swing Planes |
The machine is also capable of outside-in and inside-out swing styles for creating "side spin". The swing plane range is plus or minus 45' from square and detents at 1-degree intervals. This is facilitated by rotation of the upper frame assembly. |

| The machine is equipped with a mechanical lockout completely independent of the servo control system. When active, the mechanical lockout prevents the servomotor from all motion by engaging a large pin into the main drive, positively locking the arm at the home position. The pin is retracted by an industrial grade solenoid. When the pin is retracted, a warning light is activated signaling the operator that the machine is ready to cycle. Limit switches are also incorporated to signal the servo controller that the pin is completely engaged or completely retracted for additional safety. For emergency shut downs, the stop button on the control stand disables the motor and engages the lockout. |
