        abstract = {The rapid evolution of the Internet of Things (IoT) has revolutionized the field of mobile robotics, enabling seamless remote operation and real-time data management. This research presents the design and implementation of a sophisticated Wi-Fi-based controlled robot architecture, leveraging the high-performance ESP32 microcontroller as the central processing unit. Unlike traditional Bluetooth-controlled systems which suffer from limited range, this Wi-Fi-enabled platform utilizes an external antenna to significantly enhance signal stability and operational distance, making it suitable for complex indoor and outdoor environments. The system integrates a robust motor driver to manage high-torque 100 RPM DC motors for locomotion, ensuring precise movement and stability. Furthermore, an SG-90 servo motor is incorporated to provide precise angular control for auxiliary components, such as a camera mount or a robotic arm, expanding the robot's functional versatility.
A distinguishing feature of this design is the integration of a Micro SD card module, which serves as an onboard data logger for storing sensor telemetry, navigational logs, or captured media, ensuring data persistence even in the event of connectivity loss. The ESP32’s dual-core architecture allows for the simultaneous handling of intensive Wi-Fi communication protocols and real-time hardware interrupts, preventing latency in control commands. The software framework is developed using the Arduino IDE environment, utilizing asynchronous web server protocols to provide a low-latency user interface accessible via any web-enabled device. This research details the hardware interfacing, power management strategies, and the communication logic required to bridge the gap between web-based commands and physical robotic motion. Experimental results demonstrate that the inclusion of the ESP32 and specialized antenna provides a superior throughput and reliability compared to standard 8-bit microcontroller alternatives. This project provides a scalable foundation for applications in surveillance, automated delivery, and remote environmental monitoring, offering an affordable yet technologically advanced solution for modern robotic challenges.},
