You may never need another tennis partner again with the Swing Shot.

This robot tennis machine gives you an effective practice because it creates a less than perfect ball release and pitch by hitting it with a racket (just like a real person would).

The speed of the ball can be adjusted between 20-70 kilometers/hour and you can program the robot to hit spin, lobs, smash and plain flat shots. It is remote controlled and costs a hefty $8400.
