Night Patrolling Robot for Women Safety

Abstract

This autonomous security platform, powered by an Arduino microcontroller and programmed in C/C++, provides a robust solution for real-time surveillance and hazard mitigation. Utilizing an L293D H-Bridge motor driver for precise navigation, the robot identifies unauthorized entities within a 5cm to 10cm range via an IR proximity sensor. For personal safety, an integrated sound sensor triggers a high-decibel alarm when noise exceeds a specific threshold, while an MQ-5 gas sensor simultaneously monitors the environment for combustible hazards like LPG and natural gas. This self-contained system demonstrates the effective use of low-cost hardware to create a responsive, proactive security tool for vulnerable areas. Ultimately, the robot bridges the gap between basic automation and active hazard mitigation, offering a tireless platform for safeguarding environments and personal safety. Through its autonomous execution and immediate audible alerts, it serves as a sophisticated yet accessible example of modern embedded system engineering for security enhancement.
