Abstract - Cricket is the most dominant sport played,
balls ranging from 40 kmph to 130 kmph, two motor mechanisms are used upon which grooved wheels are mounted.
Moreover, the incorporation of a ball positioning system enables players to practice various delivery styles, simulating the actions of fast bowlers, spinners, and swing bowlers. This feature not only enhances a batsman's ability to read the ball but also provides bowlers with valuable opportunities to master different variations and deceive batsmen effectively.
Key Words: Cricket, Cost-effective, Ball throwing machine, bowling varitions, motor mechanisms.
1.INTRODUCTION Cricket a popular sport which is played by many countries worldwide [1], enjoys unparalleled popularity, particularly in cricket-crazy nations like India. As sport evolves, there is an increasing demand for innovative training methods that enable players to enhance their skills and grasp various aspects of the game. In modern training facilities, cricket ball-throwing machines have become indispensable tools for players seeking to improve their batting and bowling abilities through precise and consistent deliveries. However, existing machines often come with limitations such as manual operation and high costs. This study seeks to address these challenges by developing a cricket ballthrowing machine that surpasses conventional solutions available in the market. The primary objective is to create a fully automated and costeffective machine capable of delivering various types of bowling and adapting to diverse pitch conditions. Additionally, the machine will feature a height adjustment mechanism to accommodate players of different statures and skill levels, making it a © 2024, IRJET

2. DESIGN CALCULATIONS AND ANALYSIS The Design calculation of the ball throwing mechanism is done considering the mass of the ball, kinetic energy as well as the rotational energy of the ball to be thrown. 2.1 DESIGN CALCULATION VALUES Design calculation for cricket ball throwing machine involves motor specifications, wheel diameter and grooving, ball speed range, etc. A. Motor Power Calculated Values: Motor calculation for cricket ball throwing machines is essential in designing as it determines the motor's capacity to achieve the desired ball speeds and deliver consistent and accurate deliveries. The values are as following: a. Mass of the ball (M): 150 gm. b. Maximum velocity of the ball: 151.2 kmph (42m/s) c. Kinetic Energy of the ball (KE) = 132.3 Nm d. Kinetic Energy supplied by one wheel = 66.15 J |
