Human-Guided Four-Axis Robotic Actuation System Using Dual Analog Joysticks and Embedded Servo Control Technology

The Human-Guided Four-Axis Robotic Actuation System Using Dual Analog Joysticks and Embedded Servo Control Technology is an embedded robotics platform designed to provide intuitive and real-time control of four servo motors through two analog joystick modules. The system utilizes an Arduino Uno microcontroller as the central processing unit, continuously reading joystick positions and translating them into precise angular movements of the servo actuators.

Each joystick offers two-axis control, enabling simultaneous operation of four independent servo motors. This arrangement allows users to manipulate multiple robotic joints or mechanisms naturally, similar to industrial robotic control systems. A 12V SMPS supplies power to the system, while a buck converter regulates the voltage to provide a stable 5V supply for the Arduino and servo motors, ensuring reliable operation and protecting the electronics from voltage fluctuations.

The project demonstrates the principles of embedded control, human-machine interaction, and robotic motion coordination. By converting human hand movements into mechanical actions, the system serves as an effective platform for learning robotics, developing robotic arms, testing automation concepts, and creating prototype manipulation systems. The low-cost architecture and straightforward implementation make it suitable for educational institutions, research laboratories, and automation enthusiasts.

The proposed framework enhances user interaction with robotic systems by offering responsive, accurate, and smooth multi-axis motion control, making it a practical solution for applications such as robotic arm operation, object handling, training simulators, and intelligent automation systems.
