How to Build a Remote-Controlled Robotic Arm Using Arduino

In this tutorial, I will guide you through the process of building a robotic arm that can be remotely controlled via programming using the Arduino Integrated Development Environment (IDE). This project is ideal for enthusiasts in robotics and mechatronics, and it provides hands-on experience with servo motors and Arduino programming.


Hardware Required

  • Arduino Nano or Arduino Uno
  • SG-90 micro servo motors (4 units)
  • Robotic arm chassis (can be laser-cut or 3D printed)
  • Jumper wires
  • External power supply (for servos)


Software Required


Understanding the Robotic Arm

The robotic arm is a fundamental concept widely used in the robotics and mechatronics industries. Its applications range from manufacturing assembly lines to intricate tasks in research laboratories. Despite initial perceptions that building a robotic arm may be complex, a comprehensive understanding of its mechanics and the programming involved can simplify the process significantly.

Our robotic arm consists of four servo motors, providing a total of four degrees of freedom (DOF). The degrees of freedom indicate the number of independent movements the arm can perform, allowing it to reach various positions and orientations.
