Tennis throwing Machine Voice Control via Bluetooth of an Arduino-based and Using PI Controller

Abstract

In this article, the throwing machine will be programmed to aid in repetitive training. All tennis training methods agree that repetitive training on specific points and distances of the ball improves the player's skills and allows him to learn new blocking techniques. There have been previous studies on this machine, but ours is a little different. In contrast to random throwing, we have added voice control and training on specific points and locations, where the player can control the machine by sending a voice message via the smartphone. with the presence of Bluetooth and Arduino. The basic devices in our project are High-efficiency electric drives required for emerging technologies. PI controllers are used to control the motors' speed. Proteus 8 professional was used for simulation, Arduino code was written using the programming language Arduino IDE, MATLAB simulation for the PI controller, and the Android applications were created using the MIT app inventor The electrical circuit of the machine will be tested to demonstrate the entire project and to check the control result.
