Abstract

The proposed study aimed to design and develop an "Electro-Pneumatic Sepak-Takraw Ball Pitching Device". It is primarily concerned with designing a device that can pitch a ball simultaneously from a specified height. It has a manual feature that makes the pitching being controlled by another player thru a set of pushbuttons, and an automatic feature that enables the Sepak-Takraw ball being launched simultaneously controlled via smart phone. After the series of trials, several alterations were made in the microcontroller program and mechanical design for the automatic and manual feature. Results revealed that the developed prototype passed all the requirements and recommended to be used as a training device. Also, researchers recommend some design considerations for the improvement of the device, and these were to add more electronic features to the device and to develop an automatic swing feature up, down, left, and right to have a real-time variety of pitching angles. Researchers also recommend an oil-less silent type compressor with the big reservoir to minimize noise, increased compressed air efficiency to effectively pitch the ball without delay, and decreased power consumption due to simultaneous pumping and use of compressed air.
