Badminton shuttlecock is constructed of 16 goose feathers from a waterfowl with a hemispherical cork.The shuttlecock is light in mass (approximately 5.2g), with a knowall.blog highly specific air resistance.For professional badminton players, the highest initial speed of the shuttlecock by a smash shot exceeds over 80m/s, which is the fastest speed in all ball sports.Generally, it is extremely difficult to get the shuttlecock to speeds of over 30m/s with a launching machine without breaking the waterfowl feathers.

In this study, a shuttlecock launching machine using two turn rollers for badminton exercises has been developed with a new launcher mechanism that includes an advanced holder device and a high rotational speed motor installed.In addition, a continuous launcher system which is able to discharge the 12 (maximum 96) shuttlecocks continuously at intervals of 1.5 seconds was designed.The results of the launching experiments using the two roller-type badminton machine kicker pro comp 10 show that the machine can launch the shuttlecock at mean initial speeds of up to 81.8m/s, with a maximum flight distance of over 11m.

The standard deviation of the shot and lateral directions are approximately 0.34m and 0.12m, respectively.The launching performance of the badminton machine developed here has a performance far exceeding almost any commercial one, so the badminton machine can be used for harder practice by professional badminton players.
