Abstract
Scientific studies often require innovative approaches to capture data. Past work on anticipatory muscle activity during a multijointed task required balls of varying weights to drop straight down from a fixed height of 40 cm into the hand of the subject. A device that employs the option to drop balls from various fixed heights adds value to this area of research by offering versatility for data collection. This project aims to develop an apparatus that can hold and drop balls of various weights from three fixed heights into a "target zone." Branches made of PVC pipe make up an assembly that achieves the desired heights of 30 cm, 40cm, and 50 cm. Electromagnets in each branch create a system that allows the balls to be held and dropped as desired with the help of a small controller board. Push buttons initiate the ball drop mechanism. Extensive testing shows that, upon pressing the button, the ball drops into the "target zone" each trial regardless of the height. The housing box hides the electrical components and displays the "target zone" on the side, which aids camera technology for data collection. The option to collect data from three different heights increases the device's capabilities and widens the scope of investigative opportunities.
