*Result*: ESP32-Based Surveillance Car with Android Camera and App Control.

*This paper presents the design and implementation of a mobile surveillance robot system based on ESP32-CAM and Arduino technology. The proposed system is capable of real-time video streaming and wireless navigation, providing an efficient and cost - effective solution for monitoring environments that are inaccessible or hazardous to humans. The robot integrates the ESP32-CAM module for capturing and transmitting live video via Wi-Fi, while an Arduino Uno microcontroller manages motor control through Bluetooth commands sent from an Android application. The system is powered by a rechargeable Li-ion battery, ensuring portability and long operational duration. The mobile application, developed using MIT App Inventor, enables intuitive control of the robot’s movement, while live footage can be accessed via a standard web browser using the ESP32’s IP address. This dual-communication architecture—Bluetooth for navigation and Wi-Fi for streaming—allows for seamless remote operation. The prototype is suitable for applications such as disaster site inspection, military reconnaissance, and agricultural surveillance, where deploying human personnel may be challenging or unsafe.
