NIGHT PATROL ROBOT

Abstract

This system suggest a robot patrolling security that uses night vision camera to protect any premises. The robotic vehicle is traveling at different intervals and is fitted with camera and sound sensors for the night vision. It uses a predefined line to patrol along its route. It stops at different points and if sound is heard it travels to next points. To patrol the allocated field, system uses the following IR-based path system. It monitors every area using 360degree rotating HD camera to detect any intrusion. It has the capability of tracking sound at the premises. Any sound after the firm is closed and on its predefined course it begins moving towards the sound. It then scans the area using its camera to recognize human face found. It records and begins to relay photographs of the situation immediately after identification of the sound or human face. This is where we use IOT Local Area Network (LAN) to receive transmitted images and display them with warning sounds to the user. We are therefore proposing a fully autonomous security robot that works constantly and patrols wide areas alone to protect the facility.

Existing System

Proposed System

In this proposed device, Node MCU is equipped with the night vision camera that helps the user to go for automation and helps to find the person or any problem detected using the sound sensor and automatically goes to that area and captures the image and sends it to the user using IOT technology according to the sound generated. The robot has a range of knowledge to protect the greater region. This robot uses two infrared sensors that are capable of detecting obstacles robot on both hands. When the barrier does is at the front of the robot it changes its direction to the opposite side of it. In the robotic world, Microphone is used to detect sounds in the real time and send them to the monitoring system. The live photos and videos are recorded by the vision system. Two generators are enough to power the module for robot movement. Because the number of gears in the motor is small, less power consumption will be received. This robot will be moving front and backwards using infrared sensors with the help of wheels with the use of Dc engine. Dc engine transforms electrical power into mechanical power. This motor consists of 60 torque; this torque helps to move the wheels. Here a 12volt battery is used to supply the power to the MCU-node. Where the MCU node is used to connect to the Wi-Fi. After connecting to the Wi-Fi the captured pictured and will be visible in the operators mobile. Where the operator can turn the camera 360 degrees to check out the whole street. There is a sound sensor using in the robot. This sound sensor will sense the sound with the particular frequency and after sensing the sound the robot will move towards the sound recognized side and the camera will be switched on and the camera will record the video with the audio file. This video and the audio file will be monitored by the operator who is having with robot.
