A12 Study on Launcher Performance of Badminton Machine with Rollers

Abstract

Shuttlecock used in a badminton match is light mass, which is strongly influenced by air resistance and the wing of the skirt can be easily broken. The highest initial velocity of the shuttlecock exceeds 300km/hr for a professional badminton player. In this study, new insertion equipment and the motion control system were proposed, and an exercise machine for badminton, used to project the shuttlecock at high speeds (over 42m/s), has been developed. The mechanism of the shuttlecock launcher in this machine was achieved using the friction force between two turn rollers and the shuttlecock. The results of the launcher experiments using the badminton machine show that the machine can project the feather shuttlecock at the maximum flight distance of about 11.5m, with a standard error of about 0.32m and the highest initial speeds being 52.8m/s. In addition, the launcher performance of the badminton machine was improved by having produced the launching device which supplied many shuttlecocks continually.
