A Wi-Fi controlled Rover Robotic Arm built using ESP32, DC Motors, Servo Motors, and 3D Printed Components.
This project integrates a 4-wheeled mobile rover with a multi-degree-of-freedom robotic arm capable of object handling, pick-place, industrial automation and real-time wireless control through a web-based interface.
⚠️ Note: The circuit diagram is for reference. Always verify GPIO pins from the latest code before implementation.
The ESP32 hosts a web server that allows real-time control from any browser.

The Rover Robotic Arm combines a mobile rover with a robotic arm. The rover can move in different directions, and the arm is used to pick and place objects.
The ESP32 acts as the main controller, managing both movement and arm operations. The system works over Wi-Fi and is controlled through a web interface.
Overall, the project is designed for simple and efficient movement and object handling.
