Ball Throwing Machine Design To Develop Footballers’ Technical Attributes

Abstract

For a football player to perform well in football, it is necessary to improve his technical and tactical skills. Improving these skills is enabled with repetition of the same positions that the football player has the ball. The repetitions of these same positions can be performed with the aid of a machine. In this study, a football throwing machine design which can provide direction and velocity for the ball in a repeatable and controllable manner is generated in order for fully educational evaluation. Ball loading canister on the ball throwing machine enabled to use many balls. There are a couple of ball throwing wheels both are made of polyurethane material and have concave surface. These wheels are mounted on a body for axial rotation on a common ground. Each wheel’s rotation speed can be adjusted individually. In order to determine horizontal-vertical direction of movement of the ball, two linear actuator are used. Ball’s velocity, direction, orbit and throwing laps are controlled electronically. All controls concerning ball throwing are carried out via Delta PLC (Programmable Logic Controller) and HMI (Human Machine Interface) panel. A user interface is developed for controls made via PLC. Owing to interface, different training plans are designed by handler or trainer via operator panel and footballer is provided to train in various density. In order to prevent toppling tripod system, and to carry easily a towing arm is used. Machine can work with an accumulator or feed directly from grid circuit.
