# ESP32 Wireless Controlled Mobile Robot

This project demonstrates the development of a Wi-Fi-controlled mobile robot using an **ESP32 microcontroller** and **Acrome SMD Red** motor driver. The system enables wireless teleoperation via a web interface and features real-time video streaming using the ESP32-CAM module. It includes a wheeled base, a linear actuator for vertical motion, and a servo motor for angular control.
