Development of a prototype tennis ball launcher using two rotating wheels powered by dc motor / Czyruzzikry Czyrell

This project called a tennis ball launcher is made to propel tennis balls at high speeds in an imitation of a player hitting the ball. It is frequently used for workouts, tennis practice sessions, and even for leisure activities. This summary aims to give a general understanding of the essential elements and operation of a conventional tennis ball launcher. The launch mechanism, the ball feeding system, and the control system are the three primary parts of the launcher. The force necessary to drive the tennis ball is produced by the launching mechanism. It often uses a motor-driven mechanism to compress and release energy, transferring it to the ball upon release, such as a flywheel or a pneumatic piston. In order to evaluate the prospects for its technical realization, the study offers the mathematical analysis for the creation of a new tennis ball launcher. The description of traditional launchers comes first. Then, a number of new specifications that might improve these machines' training potential are offered. The tennis ball's motion equation is formulated and numerically solved. This makes it feasible to examine the ball's trajectory under various initial conditions, including elevation and heading angles as well as the angle of the rollers. The launcher with two counter-rotating rollers is next mathematically analyzed and displayed. Experimental measurements have been made to determine the normal tennis ball's stiffness (Young's) modulus and friction coefficients. Tennis balls can be automatically launched by a mechanical device called a tennis ball launcher for a variety of training and recreational uses. It makes use of a variety of technical concepts and processes to launch balls efficiently and with precise control over their speed, trajectory, and distance. An overview of the main elements and functioning of a standard tennis ball launcher is given in this abstract.
