Abstract

In many sports such as tennis and table tennis, there are training machines available for exercises or training purpose. The benefits in using these machines with high functionality and comparatively low cost have contributed to their extreme skills improvement. The machines setting duplicated accurately for every shots. Thus training on particular areas of the player’s game is relatively simple and more focused. Badminton players can acquire same advantages as mentioned with a shuttlecock feeder machine. There are machines rarely available in the market. One of the options for consumers is the Knight Trainer, which consists of two rotating wheels to transmit the shuttlecock. However, the cost is extremely expensive to invest in with a minimum of RM15, 000. The overall look of Knight Trainer has all the desired qualities but it does possess numerous deficiencies. From the reviews by several badminton players, the machine is unpractical, less accurate and retains high initial and operating costs. This research aims to improve the accuracy of Shuttlecock Launching System (SLS) by studying the shuttlecock trajectory. Besides, the aim to design and develop a low cost solution in manufacturing so that the SLS is allowed for a retail price comparable to machines in other sports. Research had been conducted on the trajectory of shuttlecock to predict the angles and velocities needed to launch different types of shot. From the study, a desired motor specification can be obtained by computing the torque and speed required. The results obtained with two approaches are compared by analyzing the trajectory models occurred from the simulations. The accuracy of feeder mechanism are founded (12 ± 15.8) mm and (15.4 ± 13) mm with standard deviation of 5.716 mm and 5.824 mm respectively. For the launching mechanism, results showed an error percentage as low as 4.70% at an angle setting of 22.5° for the shuttlecock trajectory. For overall system of SLS, the accuracy for angle settings of 22.5°, 45° and 67.5° achieved 20%, 0% and 60% respectively.
