Abstract :

This Work Presents The Development Of A Wi-Fi Enabled Intelligent Surveillance Robot Built On The Espressif Systems Processor ESP32-CAM Microcontroller Unit (MCU), Designed To Provide Real-time Monitoring And Remote Mobility Through A Web-based Control System. The Robot Integrates A Compact 32-bit Embedded Controller With An Onboard Camera Module Capable Of Capturing And Transmitting Images In Joint Photographic Experts Group (JPEG) Format At Video Graphics Array (VGA) Resolution. Efficient Handling Of Image Data Is Achieved Using Internal Memory Along With Pseudo-Static Random Access Memory (PSRAM), Enabling Smooth Frame Buffering And Continuous Transmission Via WebSocket Protocol For Low-latency Feedback. The Locomotion System Is Driven By Dual Direct Current (DC) Motors Interfaced Through General Purpose Input Output (GPIO) Pins, Where Pulse Width Modulation (PWM) Is Employed To Regulate Motor Speed And Ensure Controlled Navigation. Directional Commands Including Forward, Reverse, Left, Right, And Halt Are Executed Through Digital Signal Control Of Motor Drivers. The Software Framework Follows An Asynchronous Event-driven Architecture Implemented Using ESPAsyncWebServer And AsyncWebSocket Libraries, Allowing Concurrent Processing Of Video Streaming And User Commands Without Execution Delays. The System Operates Using A Wireless Fidelity (Wi-Fi) Access Point (AP), Enabling Direct Device-to-robot Communication Without Reliance On External Internet Connectivity. Continuous Video Acquisition And Command Execution Are Maintained In Real Time, Ensuring Responsive Operation. A Built-in Safety Mechanism Automatically Stops The Robot Upon Connection Loss, Preventing Unintended Movement. This System Demonstrates A Compact, Reliable, And Cost-effective Solution For Embedded Surveillance And Remote Robotic Control Applications. Key Words: A Wi-Fi Enabled Surveillance Robot, ESP32-CAM MCU, Real-Time Monitoring, Remote Navigation, Terrain Navigation, JPEG Image Transmission.
