Build a 6-DOF Arduino Robotic Arm with Web Control

Robotic arms are one of those projects that almost every electronics enthusiast eventually builds. They combine mechanics, electronics, programming, and control systems into one powerful learning experience. In this project, we build a 6-DOF Arduino robotic arm using servo motors, 3D-printed parts, and a web-based dashboard for real-time control. It’s capable of smooth pick-and-place operations and can even record and replay motion sequences. What You’ll Learn Servo motor control using PWM Smooth motion interpolation Serial communication Web Serial API integration 3D printing & mechanical assembly Power management for multi-servo systems What is a 6-DOF Arduino Robotic Arm? A 6-DOF robotic arm has six independent joints: Base rotation Shoulder movement Elbow movement Wrist pitch Wrist rotation Gripper control More degrees of freedom mean more flexibility and human-like motion. This setup allows precise positioning in 3D space. Core Concepts Before Building Servo Motors Servos rotate to
