Shuttlecock used for badminton is light in mass so that its flight locus is strongly influenced by air resistance and the wing of the shuttlecock skirt can be easily broken.It is well known that the highest launching velocity of the shuttlecock by professional badminton players exceeds speeds of over 83.3m/s (300km/hr).In general, an actual badminton exercise can not be played alone, because of the need of a partner.In the case of baseball, a pitching machine is utilized effectively for the improvement of the batting technique of baseball team members.However, there is no training server machine for badminton players, which may be highly efficient, and only a prototype of the server machine has been developed, the longest flight distance of which is shorter than 8m.There is no badminton server machine which has already achieved a flight distance of more than 10m, an initial launching velocity of more than 41.7m/s (150km/hr), and a higher accuracy of the flight locus and falling position needed for practical badminton exercise.
