🤖 ESP32 4-DOF Robotic Arm

This project implements a 4-DOF robotic arm controlled by ESP32 and SG90 servos, with potentiometer-based control and teach-and-repeat functionality.

🎯 Features

• 4-DOF control via potentiometers
• Record & Play motion sequences with push buttons
• Smooth 180° servo motion
• Compact reach (~26 cm)

🛠️ Hardware

• ESP32
• 4x SG90 Servo Motors
• 4x 10k Potentiometers
• 2x Push Buttons
• Breadboard & Jumper Wires
• Power Supply (5V)

🧠 Working Principle

Potentiometer readings (0-4095) are mapped to servo angles (0-180°). The ESP32 controls servos in real-time and can store movements for later playback.

🚀 Future Development

• 6-DOF upgrade with belt-driven actuation
• Stepper motors for higher torque
• AI-powered drawing capability
• Autonomous task planning

🌟 Inspiration

Inspired by Epson Robots, Trossen Robotics, Kinova Robotics, RobotAnno, and NVIDIA Robotics.
