This is this latest version/model of the Oukei Robot:

The machine has a MEMORY function. It can record inputted programs and remember them so next time you use the robot it will still be there. "Random" ball shooting function. Spare rubber wheels. Uses "Double Spin Technology" to serve a "straight ball" (in other words, NO spin) as well as top spin, back spin, side spin and programmable spins. Normally these functions cannot be performed by a single spin machine. Recycles balls automatically. Back-net at table as well as ball scoop net for balls on floor included. There are 9 different falling positions on the table. By pressing right or left button on the control panel, you can easily select where the ball lands and its trajectory angle. The machine has 3 modes: 1) Automatic (random, left and right placements), 2) Regular Mode (fixed falling point) and 3) Self-mode programmed by the user.Includes 144 Quality Double Fish 1 Star Hard Training balls which is a necessity for a robot as the soft training balls on the market are useless for proper training.For more information talk to the expert Paul Pinkewich who has spent time at the Oukei factory who can advise you what direction to take and in the event of a problem can advise you of the preventative steps to take to have a troublesome free time with your robot.
