The robot movement can be controlled by the user by using android smart phone. This robot consists of esp32 camera which can be uses to send the live video to the user mobile over IOT. While seeing the video use can control the robot from web browser.

This project comprises of three phases: controlling the Robot in manual mode using IoT technology, ultrasonic sensor-based obstacle detection and Metal detection using metal sensor.

The robot can perform multiple application such as if any bombs are placed at public places this robot acts as a bomb detector robot using the metal detector sensor and alerts though buzzer. The robot can be detecting the obstacles and stop the robot automatically.

The main controlling device of the project is Arduino UNO microcontroller. To achieve this task microcontroller loaded program written in embedded C language.

Objectives of the project:

• Design a multiple application surveillance robot.
• It can be detecting the obstacle using ultrasonic sensor.
• It can be detecting the bombs using metal detection sensor.
• It can be sending the live video into the web browser using ESP32 Camera.
• Bomb detection Alert in the form of buzzer.
• Using IOT technology.

RF Communication ranges in between 30 KHz to 300 GHz. RF communication works by creating electromagnetic waves at a source and being able to pick up those electromagnetic waves at a particular destination. These electromagnetic waves travel through the air at near the speed of light. The wavelength of an electromagnetic signal is inversely proportional to the frequency; the higher the frequency, the shorter the wavelength.

The controlling device of the whole system is a Microcontroller. The Microcontroller gets the input from RF receiver which receives the data transmitted by pressing control buttons in RF remote. This data is processed and acts accordingly on Robot DC motor. When the robot detects the Bomb, it gives the buzzer alarm and sending the alert SMS along with location using GSM, GPS.

This project finds its major applications while we are monitoring larger areas like political canvassing, cricket stadiums, international conferences, worship places, banking etc. This project assures us with more reliable and confident security system.

The objectives of the project include:

• Automatic Bumb detection Robot.
