Top Swing is a robot used to learn or perfect golf swings. Using computer controls, it allows the individual nuances of every swing to be taken into account, as well as the body height and range of motion of the player.

Top Swing consists of six shafts controlled by a PC, and the shafts conjoin together at a point to which a golf club is fastened.

No, it's not a Japanese wacky invention. It's 100% made in Germany.
