233 A study of Indoor Type Batting Machine Using Badminton Shuttlecock

Abstract

For professional badminton players, the highest initial speed of the shuttlecock exceeds 84m/s (300km/h), which is the fastest speed for a ball, racket or projectile sports. Many shuttlecock launcher machines have been developed, however it is difficult for the shuttlecock to be launched at speeds of more than 42m/s. In previous study, the launcher machine using the two turn rollers can launch the shuttlecock at the speeds of 52.8m/s. In this study, rubber material and new insertion equipment were proposed to rise up the highest initial speeds of the shuttlecock. From the results of the launcher experiments, it is attached guide pole makes the state of shuttlecock insertion. In addition, the launcher machine is used for the indoor type baseball batting machine, the launch conditions of the shuttlecock are examined.
