Abstract: Security and surveillance systems play a vital role in residential, industrial, and public environments. However, manual monitoring requires continuous human effort and may not always be efficient. To address this issue, a smart patrol robot is proposed for real-time surveillance and remote monitoring. The system utilizes dual microcontrollers, namely ESP32 Dev Module and ESP8266, integrated with a camera module, sensors, and a motor driver. The ESP32 Dev Module is responsible for motor control and robot movement, while the ESP8266 handles sensor data acquisition and wireless communication. The robot can be controlled wirelessly via Wi-Fi, enabling users to monitor the surroundings remotely through a mobile application. The camera module provides live video streaming for effective surveillance. The proposed system is compact, cost-effective, and easy to implement. It enhances security monitoring, reduces human effort, and provides flexible mobility for surveillance applications in homes, offices, industries, and restricted areas.
