In today’s world safety is the most important concern for all genders in our society. And that to in night, there are more possibilities of threat. So, for the safety purpose we designed a NIGHT PATROLLING ROBOT.  This robot has camera module which can capture pictures and send to control room. Also, it has GPS module in it by which we can track its location and it can give signals. It covers certain areas and detect unusual activities, if detected any captures photos, record their voices with mic and sends signal to its owner. ck of security is a significant concern in today's global scenario. Therefore, we have developed a solution in the form of a security patrolling robot. In certain scenarios, conventional CCTV cameras may not serve as an effective deterrent for security-related tasks because they are reactive, capturing events but not offering any warnings in advance. Our security patrolling robot, however, covers specific areas and, upon detecting any suspicious activities, alerts the user. This device is equipped with cameras and microphones located on the vehicle for security purposes. It scans every nook and cranny, identifying problems through its video surveillance and listening capabilities. It can detect sounds associated with issues and move in that direction, before examining the scene for any human presence. It provides continuous vigilance along with live streaming of the crime scene.
Introduction: This passage discusses using robots for patrolling tasks. Multi-robot patrolling can be used for security, search and rescue, etc. Robots can be equipped with cameras and sensors to detect abnormalities and send alerts. The control systems for these robots are crucial for their operation. There are two main types of control algorithms for multi-robot systems: centralized and decentralized. Centralized algorithms make decisions for all the robots, while decentralized algorithms distribute decisions among the robots.
Objectives: The primary objective of this research is to develop a comprehensive, autonomous night patrolling robot that enhances security by monitoring designated areas. This robot aims to detect and respond to unusual activities using a combination of sensors, including ultrasonic, sound, and infrared, along with a camera module. By integrating these components with a Node MCU microcontroller, the system can capture images, track movements, and send alerts to a control room.
Methods: The Night Patrolling Robot employs a Node MCU microcontroller to manage various sensors and components, including an ultrasonic sensor for obstacle detection, a sound sensor for monitoring unusual noises, and a camera for capturing images. When the ultrasonic sensor detects an obstacle, it triggers the motor driver to alter the robot's direction. The system also includes a buzzer and IR sensor to alert users of potential threats. The microcontroller communicates with the control room, sending visual and audio data to enhance security monitoring.
Results: This document describes a patrolling robot using Arduino and ESPCAM32 for security and surveillance. The robot uses various sensors: a camera for visuals, an ultrasonic sensor to avoid obstacles, and a sound sensor to detect noises. It concludes that the robot's functionalities can be useful for women's safety, area monitoring, and potentially other applications like child monitoring or industrial automation.
Conclusions: Night patrol robots are a security breakthrough. They use sensors, cameras and smarts to constantly monitor areas,  detecting things humans might miss - sounds, movements, even heat signatures. This means around-the-clock vigilance and a big boost to security. pen_spark
