Handoregadesiddhi43@gmail.com<p><em>Robotic arms play a crucial role in modern automation by performing repetitive tasks with high accuracy and reliability. This work presents the design and development of a real-time gesture mimicking robotic arm using an ESP32 microcontroller. The system operates on a master-slave mechanism in which the motion provided through a control unit is reproduced by the robotic arm in real time, allowing intuitive and easy operation. User input is provided through potentiometers that generate varying analog signals corresponding to different joint movements. These signals are read and processed by the ESP32, which maps them into suitable control commands for the servo motors. A servo driver module is used to generate precise PWM signals, enabling coordinated and smooth movement of the robotic arm joints, such as base, shoulder, elbow, wrist, and gripper. This setup allows the system to perform pick-and-place tasks efficiently. The mechanical structure of the robotic arm is designed using Fusion 360 and fabricated using 3D printing, ensuring accurate dimensions and lightweight construction. The system demonstrates stable and responsive performance with minimal delay. Due to its low cost, simple design, and ease of use, it is suitable for both educational purposes and basic industrial automation. Future improvements can include wireless control, sensor-based feedback, and intelligent decision-making features to enhance overall functionality. </em></p> <p> </p>2026-05-22T00:00:00+00:00Copyright (c) 2026 Advance Research in Analog and Digital Communications
