While we can't provide more info on the test machine used by the tightlipped Japanese, there's a badminton machine developed by Mats Elm worth mentioning. After bagging a spring loaded design, Elms created a machine more than 15 years ago using compressed air. Several iterations later, the machine can feed shuttles all over the court, drop short, smash and even hit lobs. It can fire randomly or based on pre-programmed regimens. The speed of the shot and the interval between shots can also be varied for up to 72 shuttles. While Elm's doesn't have a video to share, take a look a look at the rapid fire below and you'll get the point, and maybe gain a bit of respect for the best in badminton.
